What Rep range is best for putting on mass in sequence?
I know low reps heavy weight = more mass, but i was wondering in sequence.
I.E.
Set 1 10 reps
Set 2 8 reps
Set 3 6 reps
Set 4 4 reps
or
Set 1 6 reps
Set 2 6 reps
Set 3 6 reps
Set 4 6 reps
mainly i am curious for back and chest which would work best.
