1000 Calorie Challenge | The Fastest Way To Burn 1000 Calories Running?

– Right guys how much do
we think 1000 calories is? – Well Fraser I reckon it
looks a little bit like this. – Yeah. – I mean I think yes I’ve got a salad but hidden in here, I balance it out, so I reckon I’m pretty
close with my cake as well. – Are you sure, I think I’ve got plenty. – Yeah I think you’ve
gone pretty hard there on the calories, you’ve even
got a raw haggis there Fraser. – That’s probably more
then 1000 calories there. – Yeah, it does seem– – Well it goes to show
how easy it is to consume 1000 calories, particularly
when it’s food that you enjoy but then how easy is
it to actually burn off those 1000 calories? – Or more specifically
what is the quickest way to burn off 1000 calories. (tinkling electronic music) – Right well I’m first to arrive and having enjoyed our picnic yesterday and having time to digest
it, it’s now become a little bit of a
challenge who can burn off those 1000 calories the fastest. Now I’m pretty confident
here, no offense to the guys but in classic Mark fashion
I am gonna go all out from the off and just hang on,
and actually to add to that I thought I’d throw a
bit of altitude into this so I brought an altitude mask along, so I’m gonna be running at 3000 meters. 1000 calories here you come. – Oh what you doing Mark? (muffled speaking through mask) – No I won’t talk with that on. (laughing) – What’s going on here,
what are you doing? – Well, getting ready for
this 1000 calorie challenge. – Yeah, what’s the mask all about? – So, I’m gonna try and
make it harder for myself so I’m gonna be running at 3000 meters. – What you think that’s
gonna get it do you? Well I mean you’ve got
to raise your heart rate to burn your calories haven’t you. So I mean a slightly
easier way of doing it. – Oh I see what you’re doing, right, so you’re gonna get the adrenaline. – Morning coffee and a few more shots, you know, gonna just be burning calories whilst I’m standing here. – And what’s your plan of
attack for the actual run? – Well you know I’ve
got this so I’m gonna be doing a, flying down the cycle path. So I’m gonna be adding a bit of resistance and I’m gonna be doing intervals as well. – Ah so you think that’s gonna work. – I’m gonna be really working hard, having a bit of a rest, but my heart rate will stay high between,
and whilst I’m chilling out between my intervals I’m
still gonna be working as hard as you are. – Okay alright. – I missed all that, what’s your idea of burning these calories here? I mean what is this? – I’ve got an altitude mask, I’m gonna run as hard as I can for as long as I can. – I’m just sitting drinking coffee Fraser. – Go on then what are you doing. – Easy option. – Look how much clothes I’ve got on, I’m gonna be so hot I’m
gonna burn these calories, they’re gonna melt off me. I’ve got double layer trousers,
I’ve got three tops on. – How are you going to move Fraser? – Yeah well– – He’s gonna barely make
it a K down the road. – But I’ll burn a lot of calories quickly. – Scottish man in all these clothes, good luck mate. – Yeah you too, and you. – Thanks. (upbeat music) – So before we go any
further we better discuss what a calorie is. So a calorie is a unit of energy, and the calorie with a small c represents the amount of energy required
to heat one gram of water by a temperature of one degree celsius at a pressure of one atmosphere. However what you’ll usually
hear people talking about are kilocalories and they’re
1000 of these small calories, and it is kilocalories that
we will be referring too throughout this video when
we’re talking about the fuel we need to burn which comes from the fats, carbs and proteins that we eat. (gentle tinkling music) – Well guys I mean I think
I need to head up the road because I need a little bit
of a head start with this because I’m a little bit slower. Women tend to burn calories
a little bit slower then the guys so I’m gonna go and start, see you in a bit. – Best of luck.
– Good luck. – You’re gonna need it.
– See you guys. – Right now Heather’s
head off up the road, probably explain things a little bit here because as Heather’s eluded
to we all burn calories at different rates and
women tend to burn calories at a slightly slower rate then men, and also Fraser and
myself will burn calories at different rates too. – Yeah I mean we’re all different heights, weights, maximum heart
rates, threshold paces that we can run and
burn those calories at. So we need to figure out roughly how long we’re all gonna take to do that right. – Yeah so we’ve used our threshold paces as kind of a base, and that’s essentially looking at how many calories we burn at those threshold paces, and conveniently Fraser and myself have a
very similar threshold pace so we’ve taken a recent session we’ve done at that threshold pace and projected that so it works out about
50 minutes for myself to burn 1000 calories and
Fraser around 55 minutes. Whereas for Heather it will
take her roughly around, an hour and a half to
burn those 1000 calories. So if we were to head off all together by the time that we’d burnt
off those 1000 calories Heather would only be
at around 700 calories. – So that’s why we’ve sent
her off to start with right isn’t it, to make sure she
can burn that 300 deficit that she has on us right. – Yep so she’s gonna
head out for 150 calories and then head back and
then we’ll all start. You’re gonna have obviously a little bit of a head start on me as well,
so you’ll head off and back but in theory we’re all
gonna start together and all be on a level playing field. – [Fraser] Yep so as Mark eluded
to, to make the start fair I need to head off for
an extra five minutes so we’re all approximately at the same calorie starting point. – Alright Fraser time has gone. – Five minutes on you right? – Yeah, out for two and a
half, back for two and a half. – I’m off right. – Good luck. He’s gonna struggle. Well today we are running
out and back on a section of the Bristol to Bath cycle path, why? Because it’s nice and
straight, and almost pan flat with an elevation gain of just 62 meters, perfect for ensuring we all
stick with our own plans, although we are obviously
aware that different methods work better for different people, but this is good fun nonetheless. – Right 300 calories I’m
done, well I’m not done but I’m ready to go. – 70 calories done. – That worked out well didn’t it. – Yeah, you’ve done 300. – Well in theory we’re now
at a level playing field so I think it’s time to
put our different tactics to the test. (suspenseful music) Alright okay here we go, good luck guys. – You getting a push. I’m not sure these guys really understand how to burn calories quickly and sensibly. I mean Heather’s using coffee, well yeah that’s a good enough
idea but it’s just gonna wake her up I don’t really think that’s gonna help burn calories
over an hour and a half. Mark he’s trying to run at altitude, Mark’s never trained at altitude, I don’t think he realized
how hard that is, he’s gonna fall off the edge of a cliff and then he’s just gonna struggle. Not gonna burn the calories quickly. I’m just running with lots of clothes on, that’s not fun, that’s
gonna burn loads of calories so I’m pretty sure I’ve got this. I am melting, really struggling to cope with all these layers
and run at a good pace. (gentle music) – So for this video we’re all using the Polar Advantage watches
to display our calories as we’re burning them during the run. Now before this we’ve all
gone into the Polar Flow App and made sure that our
details are correct. So things like our weight,
our height, our age, our resting heart rate,
our maximal heart rate, and even our maximal oxygen
uptake which is our VO2, and also our gender just to make sure. And once all that’s in
there we can then use the Polar Smart Calorie
algorithm which uses risk based acceleration and our heart rate to calculate and continually display that all important calorie usage. – Back to the race and it
appears Fraser is catching me up on the calorie count and
I’m starting to struggle a little myself, so I think it’s time to change the tactics here. Started on 300 calories, obviously, I’m now at 340, this is
gonna be a long session. I’ve lost a bit of the drag,
still got baggy t-shirt and I don’t think there’s enough wind, so for the mental effort
that it was taking having that on my shoulder I don’t reckon it was worth it for the calorie burn. I’m relying on hard work,
coffee and maybe the fact that I had a couple of drinks last night, hoping that raised my metabolism. – I have got this one in
the bag, Fraser started is going to be overheating,
he is going to be sweating out I think he will be lucky
if he makes it through a few K before he’s stripping
all those clothes off. – So I’ve had to jettison
my jumper and my hat, because I was really,
really trying to struggle to hold any sort of pace
or actually any type of run form as well. – Heather that caffeine’s gonna
burn out at some point soon and her heart rate’s gonna
drop and she’s gonna struggle to burn those calories. Her interval session,
I don’t think it’s got anything on me just
running hard for literally the whole entire time,
and I can hurt myself, I will go hard until those
1000 calories are burned. Yeah I might have bitten
off more then I can chew with this mask idea, 3000
meters, it’s quite hard it would appear. (upbeat music) Settling into the race
and my method has meant I’ve pulled ahead of
the others on the road but still have a little
way to go with the calories after their head starts. But was we’re showing quite
clearly we all burn calories at different rates. – Well we’ve already
covered the difference in metabolisms and also
physical factors such as height, age, gender et cetera. But then there’s other factors
such as the air temperature, if it’s really hot or if it’s really cold. And then the physical
stresses, if you’re stressed or if you’ve got fear
that will also increase the rate at which you burn calories, as will altitude, also
if you’ve got an illness or a certain injury as well as some drugs, and another factor which gives
Mark a bit of an advantage if you’ve got an increase
in lean body mass that will also help the rate
at which you burn calories. (upbeat guitar music) Well I think Fraser’s already caught me up on the calorie count
and he’s running steady, it’s not really fair. – I’m currently at 820 inside the last 5th and I am regretting saying
yes I would do this. (bleep) hot. – I’ve just received an update, Fraser is really struggling, had to ditch all his kit on the side of the road, hopefully not all of it, and Heather, well she’s had a bit of a cold, she’s struggling to do those intervals. So looks like I’ve got
this one sealed up nicely. Alright end of the line, well kind of, half way anyway. Right back we go. – Well I’m past Mark, I
think he was 150 calories behind me so we could end
up being fairly similar but Fraser when he passed
me, he was only like 20 calories behind me. (speaking off camera) Oh bugger, excuse my language,
oh fuck I’ve got 182. – With Fraser extending a
lead and Heather and myself being very close I realized I needed to up my pace somehow. If I wanted to beat
Fraser to 1000 calories this was my only way now. I think my calculations
earlier were a little off. But yeah I think there’s
some interesting science behind this because I
obviously have been running for near to an hour, over an hour, can only hold threshold for so long, so my heart rates gonna reflect that. It’s not gonna be through the roof because I need to maintain that, so yeah I think obviously
conserving the calories almost going at threshold, but it’s
been a really interesting study very close to finishing now. – [Fraser] So at this
point in the closing stages I realized that the extra
layers had actually caused my heart rate to spike to such an extent that there was no coming back from it, no matter how much I backed the pace off. However ironically this
seemed to play in my favor as it actually accelerated
my calorie burn rate, which resulted in my hitting
that 1000 calorie marker sooner then anticipated. – [Mark] Finally 1000 calories,
after running at around threshold pace for around
an hour I was watching every one of those calories
tick by towards the end, that hurt a lot. – [Heather] Oh wow, I was
relieved for that to end, it ended up being a total of 13 lots of one kilometer efforts, and I was really starting to feel it, that’s
the biggest run session I’ve actually ever done. – Wow guys that is not
something I wanna repeat anytime soon, again but
what was the fastest way of burning 1000 calories then? – Well I think we all know
who won the challenge, which tactic won the
challenge, come on Fraser. – I don’t feel like I won anything because that was really
hard work but yeah, layering up definitely
meant that I burned calories quicker then I expected too I think. – Well out of interest
what was your heart rate, what did you find it sitting at? – Average heart rate was sitting about 195 which is really–
– Average. – Yeah, yeah towards the
end, so really quite high. – That doesn’t sound healthy. – No it’s not, and I
think what happened was, effectively I was able
to run at a good pace for maybe 15 or 20 minutes, which is fine, but then the fact that I
was wearing all those layers caught up with me, the heart rate spiked and then I was never
able to drop it back down even though I did– – But you didn’t need too,
that’s great for the challenge. – Yeah, but for–
– That meant that you had to run for the least amount of time. – Yeah it did but in a much
more uncomfortable state. – Well it seems like the boxers
are on to something then. For myself yeah, my heart
rate spiked at the start because of the mask but that was just, as much as I wanted to
carry on with the mask I was spinning out, I felt light headed, I was at 3000 meters and I’m
really unfit at the moment. So took that off and my heart
rate was just steady eddie and I guess actually on
reflection I was running at threshold, or trying
to run as fast as I could for as long as I could, and that ended up threshold pace which is
something that’s sustainable for about an hour. So my heart rate reflected that
which wasn’t anything crazy, it was around 150. – Lucky you.
– Well yeah. – Did you notice your
calories burning faster whilst you had the mask on, or was it just too early to tell? – No I think it did because
then it steadied out a little bit after
that, but yeah it wasn’t what I expected because I
really felt like I worked hard but yeah interesting though. It’s not exact science let’s be honest, but interesting, how about yourself? – I was disappointed with how long I had to keep doing these K reps, and I thought that was
gonna burn it quicker, my calories were moving
quicker towards the end so I think as a result that I’m probably still burning calories afterwards. So the training effect and the
actual burn effect afterwards is longer lasting and it’s
a good session I suppose. But I think it would be really interesting if we could go and do
all of these actually with a VO2 test with a mask on, and actually have a VO2
test and your exact calories because obviously, as we said,
it’s not an exact science. But definitely been
interesting, and if you did purely just want to burn the calories, then I think Fraser’s method works. – Not recommended to everyone. – I wouldn’t try it at
home, definitely not. – Fraser I’d love to know
how much weight you lost, or how much fluid you lost. – We drank a lot when we
got to the finish for sure. – Yeah, well guys if you like this video please do hit that thumbs up button, if you’d like to see more from
GTN just click on the globe and subscribe. – And if you wanna see
another presenter challenge where we actually work together as a team to conquer the Lanzarote course record well that is just down here.

  1. Just thought of a song which should have been played for mark.

    teenage mutant ninja runner
    teenage mutant ninja runner
    teenage mutant ninja runner
    athlete with a face mask

    because he kind of looks like shredder with that mask on 😉

  2. Excellent example showing what fighting heat is more calory demanding than fighting cold.
    Unless that cold indeces shivering. Whilst shivering, you might probably burn calories the fastest way it could be possible: good luck to hold it for more than 5 minutes, thouch it might be worth 1hr running.
    Here are lifehacks for fast burning:
    – shiver
    – sweat a lot (including in Sauna or even in a basic hot bath)
    – skip a meal once in a while. It's also good for fat metabilism boosting. And if you donate those money saved on food for a local (global are cheating) charity, may God bless you in all your endeavors.
    – HIIT sessions that cause your skin oxigenation drop not just by the end of the session, but for hours… and hours. That will ensure that you are burining calories after the training, as HIIT advocacy claims.

  3. you know those masks dont actually make you get any altitude adaption lol. they are the equivalent of breathing through a straw

  4. Hiya, I love you guys. I always look forward to your next video. I love too run and I have a few half/marathons in the summer. However, I have always found hill runs the hardest. Is there any advice to help. X

  5. Looking at Fraser’s tactic… could you guys explain and give advices about running overheated on triathlons? Usually half and full distance triathlons run segment takes on those hours where the sun bites. I struggle on overheating knees for example

  6. Well the caffeine wasn't going to do anything- Heather's probably developed a tolerance to it as some runners do when regularly incorporating it into AM running routine

  7. You might consider:
    When you lose weight, where does the fat go? (Great TEDx Talk)

    In all seriousness, the 'Presenter Challenges' do help remind us(me) that you are actually still doing it – I know that sounds wrong, but there are so many shows that are difficult to relate to because you're being lectured at. Episodes like this, for me at least, show that (although nowhere near your league) I'm striving for the same thing… Thank you.

  9. 195 for an hour? Bonkers!!! I would have bet Fraser would just dehydrate himself without burning more calories, the more you know!

  10. Yes someone finally had the same issue as me. I live in Brisbane. I try slow down but heart rate doesn't go down a significant amount (maybe 190 to 185) which for the amount I slow down isn't worth it. At least someone who has a high heart rate shows once it is up it is hard to bring down

  11. Altitude mask has got to be the worst idea ever for burning calories. Restrict oxygen, which is needed for aerobic respiration to burn more? Wrong, just exactly wrong. You need oxygen to burn calories, and you need to exhale co2 to get the waste out of your bloodstream so you can keep the process going. It's actively preventing you from achieving your goal. The heart rate monitor may be fooled by the high heart rate (due to poor blood chemistry), but you won't actually burn as many calories as you would have otherwise.

  12. Can someone teleport me to that lovely park? With birds singing and spring evolving – what a great place to smash the calorie challenge 🙂

  13. To be honest. 1000 Cal is just 1Kcal. You pretty much burn that in a heart beat or maybe two. You burned 1.000.000 calories!! cheers 🙂

  14. Would love to know the total distance each of you covered during the challenge! A rule of thumb that a lot of people seem to use is that running burns approx. 100 kcal/mile, regardless of pace/HR/etc (though varying with body weight) and it would be interesting to see if this lines up at all with your challenge!

  15. This video shows 3 ways of cheating the calorie estimation algorithm by elevating their heart rate compared to their individual reference.

  16. I'm not convinced by the theory that running overheated would burn more calories. To me it is quite counter-intuitive in fact. The equivalent on the bike would be riding on a turbo trainer without a fan, you overheat and the heartrate spikes, but you can push much lower power than you could do with sufficient cooling. Wouldn't the higher power result in more calories burnt? Maybe you can do some testing in a lab, measuring the exhaled air to determine how much calories have actually been burned.
    It's not your heart that is burning the majority of calories (that is, using the glucose), it's your muscles!
    While heartrate is an indicator of how much your muscles are burning that logic does not work in the other direction. Drinking coffee to burn calories is like wiggeling a pedometer and then estimating that you ran about 10 kilometers.
    That's why you use threshold power and relate it to a certain heart rate in advance to calibrate the device so that it can estimate the actual power output via the heart rate.

  17. This should have been called who can cheat the watch the most. It's hard to believe athletes that benefited from proper training could come up with such misguided ideas. Yes, running in hot/ high/ humid environment is difficult, but not because it actually allows you to work the most. When you don't have the oxygen, your muscles can't do the work. And when you're overheating, your body has to pull back, you know, to prevent you dying. Heat is the product of energy "burning" and it has to be removed because our bodies have temperature limits. If you can't remove the heat, you can't burn the energy. Good cooling is prerequisite for maximum efforts. It's like thinking your car will have high fuel consumption if you remove the ventilator or block air intakes. No, it will just overheat. Yes, your body working hard to supply oxygen or shed heat will surely increase energy consumption of those systems (like heart using more energy because it has to pump more), but it's actually limiting you and it's not a very bright idea to stress your body like this unnecessarily. And if Heather likes her coffee with sugar, I wouldn't be surprised if she drank more energy than burned by increasing heart rate. Your heart pumping faster won't cause your legs to suddenly become less efficient. And I imagine your legs burn way more energy than your heart. However, it would never occur to me that spiking my heart rate could have positive effect so no reason to look such things up. Heart rate works as an indicator as long as it was increased by exercise. If you increase it by other means, you're just messing with the calculation. Which is, after all, the argument for power meters.

    I was expecting to see one of you trying proper high intensity intervals. They're well known for efficiency. It would be interesting to see how it compares. Generally, if you want to burn energy faster, you need to use more muscles (which is why e.g. rowing is pretty efficient), or you need to up the intensity.

    When I saw the title, I was like: What kind of nonsense is this? A thousand calories is nothing. I just had a piece of a chocolate bar that had 38 grams and 860 kJ. That's about 205 thousand calories. In 38 grams. But then I realized you're British and you Brits like to be different. 🙂 Actually, a milion calories is a pretty big meal. Half the recommended daily intake I believe. If you eat actual food. Yes, in chocolate, cookies and such, it's not that much. Under 200 grams.

  18. This video only demonstrated nescience. All of the presenters found ways of tricking a computer program, not of doing the work necessary to burn the calories. There is no short-cut to that.

  19. despite its name, it is not an altitude mask. studies have proven that it does not simulate altitude at all.
    All the mask does is provide airflow restriction and thus only strengthening the respiratory muscles.
    Altitude decreases the partial pressure of the air and so thus "less oxygen", restricting the airflow still allows for the same amount as oxygen to be inspired due to no decrease in the partial pressure of the surrounding air.

  20. That's actually not an altitude mask. If you wanted to simulate altitude, you would have to change the partial pressure of oxygen in the atmosphere which the mask cannot do. All the mask does is make breathing harder. While it may feel like you're at altitude because you're breathing harder, the partial pressure of oxygen you're breathing is the same. 🤓

  21. You guys really need to do a follow up on this one for the beginners. I have to speculate a lot about your motives and objectives to make anything of this video. Also I think it can be very hurtful for obsessive weight watchers.

  22. Watch algorithm is basically going to treat 195 BPM like a VO2 max run that never ends. Doesn't mean you actually burned more calories, just that the watch says so.

  23. I doubt that heartrate is an accurate measure of power output and thus enrgy consumption – too many influences on HR that are not power-related. You better repeat it with spirometry.

  24. Isn't the fastest way to burn calories doing Kettlebell Swings? Also, Burning 1000 calories from the glycogen tank, or from the fat? And then Rohrertech makes good points. Isn't the amount of calories the measure of work (in this case moving your body weight) over time. Higher heart rate does not mean more calories. I really love your videos, but I find this one to be a bit of a silly one. Am I wrong?

  25. Why do you think that the watches will give accurate numbers? Aren't they based on estimation for normal conditions?

  26. Great channel guys..
    1.OK before I finish watching surely Swimming burns the most (Care of Olympic reports on calorie intake during training… 3000 calories plus.. geez)
    2…& the theme in these vids is clearly ON footware (for the win)., Ive decided against Nike and Im going full Swiss ON footwear (If Brexit UK can deliver me a pair on time ).
    3. I dont give 2 *** about calorie burn, its all about burning off the FAT m' lud., please consider a video or two about fat burning. PS( I seed all energy excursions with a tiny amount of sugar, best for this? tiny handful of currents/raisins… fat burns best in a sea of carbs. ) PS Women burn fat less also because of their lower body mass .. so Im not sure its as differential as it seems. (Biochem Grad here)
    4. ok finished… no swiming, it was relatively done through running. ok .. all good. enjoyable little journey.

  27. Could we all take a moments silence for the reduction of the sugar content in Irn Bru. Once a nations pride and joy, now a bubblegum flavoured water. RIP my hangovers will never be the same. Xxx

  28. How can we trust any of this if you think an 'altitude mask' actually simulates being at a greater altitude. It just makes your respiratory muscles work harder, but doesn't change the partial pressure of O2 at all. It actually limits the rate of adaptation to the aerobic system because of the lack of O2 volume consumed for aerobic energy production. Retarded.

  29. Try that one! 😂


  30. I wonder if they wore chest straps. I know my garmin can be way off sometimes on the heart rate when running ( its exact when not moving around ). That false reading would skew all the other stats, like calories

  31. I'm surprise that this folks made the biggest mistake in the world – this mask don't reduce the amount of the oxygen like you have at 3000m but only restrict the amount of the air … make it right next time

  32. The only use for these measurements are in relative terms to your other tests. There no accuracy in the heart rate monitoring, or other parameters, as well. That's how I personally find benefit in such measurements.

  33. This is all assuming the calorie burn is accurate on a watch. Also, I don't think they were really running threshold if they could talk to the camera fairly casually.

  34. Putting on multiple layers of clothing doesnt make you burn calories…it makes you sweat and lose water, which is losing water weight, not burning calories.

  35. I spent 50 minutes on a ski stepper machine and it said I burned 650 calories, I'm pretty sure the machine is wrong lol

  36. When I want to lose weight quickly, I wear I layer with plastic. A cotton T-shirt to absorb the sweat, then a black plastic bag, then a tight fitting top to keep the bag from making all that noise then a large T-shirt, then a jumper. But I do my running at 05:00am in the morning. Do static stretches.
    Then a good warm shower makes my body feels good ready for the day ahead.

  37. On the process of creating energy, atp is consumed in aerobic resperation. In this process, oxygen is mandotory, and if you use an mask, you will burn less calories

  38. I don't understand why elevating the body temperature ot creates a greater calorie burn. Of someone cold explain me i would be pleased. In my opinion, increasing the body temperature is not a good idea, because your muscles have an optimal temperature to work, so of you mess up with that, problably you will get less calories burned

  39. Sigh. I'm going to try to be nice and not use derogatory words here, but this was dumb. Just because something is harder doesn't mean it'll burn more calories. Put a thumbtack in your shoe and it'll be really hard to run, but you won't burn more calories. To burn more calories, you have to DO MORE WORK. So … running with a parachute – yep. Running with a weight vest – yep. Running up hill – yep. Wearing more clothes – not really (just the weight of the clothes is slightly more work). Reducing the amount of oxygen – will REDUCE the amount of work you can do. Intervals – over all, you'll burn fewer calories than a steady run because your average work rate, once you include the rest periods, is LESS than the average work rate of a hard steady pace run. You can also increase calorie burn a bit by increasing heat production (wearing more clothes doesn't increase heat production, btw, it just reduces your ability to shed heat). So caffeine or thyroxine will cause some increase in BMR and thus increase heat (calorie) production. Seriously. Do the math (or, in your case, "the maths" 'cuz you're in the UK).

  40. 195, thats a lot! I have clocked average of 187 in a 40 min competition once, but I think my max heartrate is 193.

  41. The fatest way to burn? Do not over eat, get smaller plates, do not eat processed food and limit your intake of dairy and meat. tada ….. This insane need to find the magic pill is idiotic. I like they are trying to make a bit scientific but it will absolutely not help anyone at all. It has been shown time and time again that just being active is enough, walking seems the best to lose weight. Just stop using these cars constantly. This is all due to fact we are bombarded by the commercials and pseudo science of big corporations and oil companies. And if you age stop eating 3 meals a day since you dont need that much calories. People tend to forget you need adapt your eating habit as you age.
