Generally, proteins you eat get broken down by the digestive system into their component amino acids. There are some notable exceptions where proteins can apparently get absorbed intact, but generally proteins are broken down upon injestion. Supplementing intra-venously might be the only option.

And even then this protein may provide negative feedback for the production of other unidentified proteins, which are kept in check by the exercise activity, meaning that flooding your system intravenously could lead to some undesirable or harmful results.

I think it's really interesting to mimic certain positive effects by various substances.

One example would be Resveratrol, that mimics caloric restriction. For exercise, the challenge seems to be quite hard (http://sydney.edu.au/news-opinion/news/2015/10/02/exercise-i...), but there can be seen some progress in animal models (https://www.washingtonpost.com/news/to-your-health/wp/2015/0...).

Does supplementing this protein cause the brain to absorb it at the same rate as exercise? Doesn't exercise increase the brain's ability to absorb certain chemicals (probably a bad way to phrase it, mentioned elsewhere on this page).

well I would argue that other benefits of exercise cannot be simply ingested.

a lot of people cant exercise though

I don't think that is true whatsoever. There might be a few people in millions who absolutely can't do anything.

Everyone can exercise, no matter what condition: bad heart, missing lung, missing limbs, etc. There is some form of exercise that can be done. You name a condition, I'm sure I can find someone on youtube with that condition absolutely crushing a work out.

Very very few people are physically disabled to the extent that they can't exercise. I see people who walk with canes lifting weights. Water aerobics can also be a good option.

> a lot of people WONT exercise though

Honestly, considering the overweight and obese population is growing we have a problem with systemic overeating that needs to be corrected first. It doesn't matter how much exercise you do if you eat more than you need.

Even if you grant that many overweight/obese people merely won't exercise, certainly at least some people can't exercise.

The important question is how many people _can't_ exercise, and why, and what exercises have they tried?
