Question

muscle mass can affect a person's flexibility

Answer 1

true, just like fat, it gets in the way

Answer 2

but you would have more strength to acquire something as like a back flip if you had enough upper body strength then you would be able to do it easier i think idk depends on what you are wanting to do for flexibility

Answer 3

muscle strength helps and stuff but the mass itself is a cordon obstruction
