Thread: Mass muscle groups

I think the back muscles would run a close second.

You heard wrong. 1-6 reps is for strength gains. 8-12 is best for hypertrophy ("mass building").

Also another question. Since doing 8-12 reps increases muscle size so muscle is being added and muscle weighs more than fat, that counts as mass building too, right? i heard that mass building should be done in low intanse reps (1-6) so i was wondering if 8-12 reps was exeptional also.

Lats then chest


Mass "Hypertrophy" is the 5-15 rep range....but even more than that to a lesser degree.
