This may be posted in the wrong part of the forum if so I'm sorry.
I've been training 4 times a week.
Monday - chest/biceps
Tuesday - back/triceps
Wednesday - rest day
Thursday - shoulders/biceps
Fridays - legs: triceps
I'm just wondering should I do abs and forearms on Wednesday instead of resting?
My goals are to add mass my diet is good and my exercises are also good.
