That's a decent start - that will give him a balanced program for 4 weeks. Increase the load each week. Rest 60sec between pairings, workouts should be less then 45min. Don't train on consecutive days. You can build up tolerance to training fullbody with less then 48h of recovery but i would not recommend it at this point.
