Due to family, work, and continuing education responsibilities I'd like to train twice per week. My main goal right now is gaining mass (currently 170 lbs, 5'10"). Can I efficiently gain muscle mass (I'm aiming for a minimum ratio of 60%muscle/40% fat, cutting down later is easy) training full body twice per week?
For the record, key movements I'll be using include squats, deadlifts, overhead presses, bench presses, pull-ups, rows and core work. Thanks,
