Lost 39 lbs since Feb 26 walking, cycling, diet and cpap (sleep), I've seen a huge difference in speed riding the same course 3x a week. I own a cheap aluminum road bike but our local pro shop said not to invest any money into making it lighter and go for a carbon road bike and upgrades. In the mean time, doc needs to see another 135lbs (61 kilos) gone...
Nice man, keep it up! I’m still on my old aluminum bike and figured there was no reason to get a lighter bike while I could stand to lose 30-40lbs myself.
Keep it going fella. I lost 15kg (20%) in a year. So much easier. I agree with the shop, go full carbon , and don't do cheap cheap lol. Trek/scott/giant with 105/Ultegra. World of difference.
Losing body weight (from fat) has a snowball effect on you. (Been there, still doing that). If you have excess fat, it is not just the same thing as a weighted vest. Excess fat hurts your sustained power, as your heart and lungs are overworked from the excess fat. You are also more sensitive to heat. There is also the aerodynamics, the position, the saddle discomfort and possibly chaffing, overheating and excess sweat .... I would trade my fat weight for a weighted vest any day !
Thanks for this video! I just recently had an argument with a guy telling me that a kilo at the bike is like 4 kg on the body, which I didn’t believe. Thanks for the proof!!
9:05 i have a theory, a round object is more aero than a flat. So a ‘bear belly’ should be more aero than a thin guy, maybe test this in a wind tunnel?
This is not a real comparison. Losing body weight in reality means the heart won’t have to perfuse that extra bit of body fat and your body should be more efficient. This is definitely not the same as putting on or taking off a weighted vest…
So basically they should have used up weeks or even months to put on weight which would have made not much to be noteable on performance differences in the test. Plus what you say could result in them having more muscle mass. So in reality what you say is pointless as it would have token too long to make the video and would make a very insignificant impact to the results.
Another thing to consider is when you lose weight from yourself “in the correct way”, you tend to get fitter as a result and also able to sustain power for longer. I’ve lost 7st in the last two years and I can put out more watts for longer and obviously a hell of a lot faster… I did also buy a new fancy bike. But I’m sure that didn’t make that much difference
Same here! It’s gradually going and I am seeing the effect on my ‘favourite’ climbs. PR’s very often now as my weight drops. Lost 20kg already. Just under 18kg to go until I’m at my ideal weight. The weight I was as a competitive swimmer. That was 35 years ago though!😯
I've recently gone on a bit of mission to get myself back to where I was and, in eight weeks have shed 11 KG. It struck me that the weight I've lost is actually more than the weight of my bike. So (probably over-simplifying this). We've probably all got far more potential of shedding weight from us than we have from ourselves because I'm still losing weight - and the equivalent of my whole bike has already gone.
I've been training for triathlon for nearly three years now. I live in Finland and ever since I started to train more with other athletes around here I've discovered that they actually use even eight zones: if a HRM (mine is Garmin) reports five, they split the three middle zones - Low Aerobic, High Aerobic and Threshold - into two, calling them (actually in Finnish, but I'm giving a similar logic in English here) like LA1, LA2, HA1, HA2, T1 and T2. This is so prevalent that it's taken up in discussions all the time, and also used by coaches, which is why I've adopted some of it to my own training as well. I have found splitting especially the LA zone into two to be somewhat beneficial: previously I've often ended up just spending the majority of my training time only few beats below my HA zone lower limit (because everyone knows that doing LA exercises always feels soooo slow), but now I'm sometimes trying to force myself to stay on the lower half of my LA zone instead, to really force it to be very easy and relaxed.
I have gained 10kg in the past year. I came from a background of restricting and under fuelling. I now find hills a lot harder and my power has not caught up with my weight gain. However I am healthier and happier and hopefully more sustainable. Weight loss is not necessarily a good thing!
I know if I lost some weight it would help with climbing and aerodynamics as my belly wouldn't be as big and I would be able to get lower at the front. Currently, the legs are hitting the belly when in aero position.
Power to weight is applicable ONLY for climbing. It doesn't factor in on flat, downhill, headwind, tailwind, crosswind, rain, or cold. However, body weight does factor in every step of the run.
I don't think "power to weight is applicable only to hills" strictly true, the power to weight difference will be markedly less noticeable, but you'd still be faster on a flat if you weighed less for the same power... drag through friction would factor more prominently from tyres, although you can store more power, every time you break you lose more of it to heat if you're heavier, the only real benefit is for downhill.
@@ljadf For a given amount of power gravity will factor into the top speed achieved when going up hill or down hill. On a flat surface gravity doesn't help or hinder. If gravity isn't a factor then weight isn't a factor. On a flat surface all the power is going to overcome friction losses and drag.
Nice but... There is a lot of difference to being 4kg to fat or carrying 4kg in a backpack. Even more when you run ! The physiology is completely different.
@@brienfrazer9048 I can explain a bit. The weight is distributed differently when you are wearing a backpack so your center of mass will change. Also, aerodynamics will change because a backpack will change the shape of your body
She produced only 190 watts, he produced almost 500w???? They're both equally trained athletes, right? How can the difference be that big? Is it because she's a woman? I can't say with certainty but I vaguely remember the differences between manon and the other presenters of GCN being a lot smaller.
@@trepidati0n533 I would agree. Except: Genetics - she won some triathlons right? So her genetics should be bove average. Gender - hence my comment about manon; normally women are weaker than men, but cycling seems to be a sport both genders can do similar performances. Women are still less powerful, but NOT less than half as strong. and possibly the amount of current training the individual has - most likely explanation but as I said - arent they both equally well trained? Or has heather fully retired from competitions while mark is planning on doing competitions soon? Heather was close to the birtish champion in swimming, so I tend to think she is trained. So.... none of the explanations fit, hence my comment. I am truly shocked at that 190-450 watt difference and i cannot explain it.
I know Heather always says the bike is her weakest discipline - she is an amazing runner and swimmer though. With FTP - mine looks crazy low compared to my husband when we road cycle together and I am usually the lead rider. It is better to look at watts/kilo - we are both sitting on between 2.2 - 2.5 w/kg so because I am lighter my watts don't need to be as high. (If I could get my power as high as my husbands I would be stoked and I would also do better at a lot of triathlons !)
Probably the gearing on the TT bike power is a function of force over time so you need to be spinning at 90+RPM for short efforts, otherwise the numbers look low and the effort is high
She said climbing wasn't something she did. She also remained in the saddle while he stood. She won a silver medal in the Olympics in pentathlon which includes running and swimming but not cycling.
Instead of using, let's say, 500g metal pieces that could be duck taped to frame/inserted into pockets for body weight, GTN used big bags, that greatly affected aerodynamics. That's not the way to do "science".

Was looking for the ride with no added weights for a comparison.
why was the test on a hill lol.. youre on TT bikes, do it on a flat course

A bear belly 😅
Gcn tested this with a backpack on the front. It was faster.
@@111bonus joking or serious? Lol
@@futures.scalper.808 serious. th-cam.com/video/Z4Te-wrCQsM/w-d-xo.html
lost only 5kg and the same routes feel much easier. will award myself a carbon bike after losing another 30 kilos 👍

Very true Vinay, the body adapts other processes as weight goes up or down. We are slightly more complex organisms than diesel trucks.
Definitely more cheap to lose weight on yourself! And more healthy too.

I have 20+ kg more than I should. No need to choose where to loose))
Losing 20+ kg from the bike would be impossible in most cases 😉

Body weight is metabolic. It not only weighs you down, it also takes up some of you metabolic capacity.
I have gained 10kg in the past year. I came from a background of restricting and under fuelling. I now find hills a lot harder and my power has not caught up with my weight gain. However I am healthier and happier and hopefully more sustainable. Weight loss is not necessarily a good thing!

Would like to do a bit of both, however I think eating less cheese is probably the most viable…
Are you mad!? 🤣🧀❤
We've all been in lockdown so we all know the answer as to where the weight needs to go from 😂
Definitely have some weight to lose. Great video! Thank you

An extra 22lbs or 11lbs is not a small amount of weight to add. No wonder you’re exhausted, got you’re weight training in too.😳😳😳
The guy produced 459 watt 😰😰
I'm a fan of this page but I don't know who these people are..
I'm just here for the content 😅😅
Happy medium - both 👍😊
Alternate title: GTN presenters ride like me for an afternoon
So say you are adding roughly 5lbs regardless.. meaning.. water, tools, food, etc.. is it better to have that weight on your back or the bike.
Nice but...

Even more when you run !

Hi Ib,,, can you explain please?
@@brienfrazer9048 I can explain a bit. The weight is distributed differently when you are wearing a backpack so your center of mass will change. Also, aerodynamics will change because a backpack will change the shape of your body
Losing body weight will improve run times also. I've been losing 5 kilos for 5 years! Weight stays same.
Please review hydration while swimming
Would that be an efficient way of training?
Losing 5kg from your bike! Time to get the drill out again
What was the conclusion / results?
Next time, try to put on more weight when swimming :-)
Science says there is no way it can matter where the weight is at such a low speed, and probably not at a much higher speed either.
I need that longsleeve !
That FELT (is) amazing! Hahaha

Emptying water bottles is a good idea.
Knowing I need to lose about 4.4KG this video makes me feel fat 😄
I need to lose a few kilos. Will be better for me all round. Pardon the pun.
If you loose weight you also loose some muscle, which would offset some of the savings from the lost weight.
Felt looks clunky and heavy

Yeah, they're pretty much just finding excuses to make content, any kind of content, daily.
Aero doesn’t really matter uphill
First
Rubbish ..weight on the bike is much easier than weight on self as one cannot ignore biology
Tri bikes are so ugly!
