My little brother (5'8", 118lbs, 18 years old) wants to get into weight training. He has very little time to actually work out. Would a fully body like routine, twice a week for 45 minutes be enough to help him build a little muscle? Given proper nutrition, is that really going to be enough time in the gym to gain any mass?
Example of routine:
BB Bench Press or DB Chest Press
Inclined BB or DB Chest Press
DB or BB Lunges
Bent-over DB Rows
Military Press or DB Shoulder Press
I am open to any experience and advice for him. He's never done weight lifting. I told him to start doing 3x10 on most exercises to get used to the form and movements. Maybe a month of that and then to move to a heavier weight and lower rep scheme? As long as he pushes hard enough, will he be gaining mass/ increasing strength? Thank you WWB people.
