Why do we have to tire the body in order to lose weight or gain muscle i mean if the body knows that being active makes it develop muscle isnt there a way to trick it lol
Go with that to a bio lab an intresting idea lol but I guess that's what steroids kind of do plus you still have to work to get where you want to be at least in the today's world, anything is possible in the future
When we overwork the muscles they develop tiny tears and rebuild to a bigger stronger size. There is a way to develop strength without pain though like in yoga. That is by following the breath and working just under the pain threshold. But that is nerve strength.
