I have read Internet,as I read body fat doesn't play a role about help buidling muscle.As i read need diet with foods,protein etc.On the other side, specific the opposite aspect of view,on thin guys,they need and body fat.It can't have someone mass body with not body fat.What I want to say ok ,it may need protein etc the muscle but with body fat I think, the muscle , is more visible.So,conclusion my question is if want to have a visible biceps does body fat help or it does "bad" to gain muscle? I will make an exception to abs.I know to define more the abs low fat needs.What about other muscles? Thanks
Your muscles will be more defined if you have less body fat covering them up.
Muscles are built by protein and amino acid structures, fat has a role to play in nutrition but it lacks the ability (amino acids) to construct or repair muscle tissues.
