God sake, the guys 13 years old and you saying he should do big boy basics and others.....and diet....the kid lives at home so he aint gonna follow a BB diet...consult the brain before the mouth. Think about it, did u ever follow a BB diet when you were 13 yrs old? The kids gotta have a life....he's got school, friends, family and fun stuff to do, not workout all week and eat to a BB schedule. Yes he should eat good foods, but hey give him a break...
At 13 he should be doing exercises that are basic and help his development.
I would do 1 -2 at the most workouts a week
Swiss ball DB squats: 2 x 15
Lying leg curls: 2 x 10
Db bench press: 2 x 10
Lat pull down: 2 x 12
Trap bar deadlifts/ or Db deadlifts: 2 x 10
Standing calf raises: 2 x 10
Db shoulder press: 2 x 8-10
seated cables rows: 2 x 15
