Weight training for 14 yr old

Olympic lifting with a good coach.

If you’re in Baton Rouge, Matt Bruce trains lifters at RSCF nearly every day from 3-6pm.

Make sure he is learning the correct form from day 1.

Also, don't underestimate the importance of flexibility. Make sure that's a part of his routine. It's one of the most important part of any athletics he will participate in. Warm up, stretch, lifting/cardio, really good stretch to end. Yoga is great also.

I’d recommend “whole body training” where he works out a muscle group per day:
M: chest and tris (3-4 sets of 8-12 reps, 3 exercises for chest(flat barbell bench, incline dumbbell bench, incline dumbbell flys, 3 for triceps(close grip bench, skull crushers, cable extensions press)
T: Legs (6 sets of squats 8-12 reps increasing weight, 4 sets of dumbbell lunges 20 reps each, 4-5 sets of leg press 10-20 reps each set, 4 sets of 10 quad extensions, 3 sets of 10 hammy curls, 5-6 set of calf raises)
W: rest day
Th: Back and bis (4 sets wide grip lat pull down, 3 sets close grip lat pulldown, 4 sets of single arm rows, 4 sets seated rows, 4 sets preacher curls, 4 sets alternating dumbbell curls, 3 sets incline dumbbell hammer curls)
F: Shoulders (4 sets barbell or Smith machine overpress in front, not behind head, 4 sets dumbbell Arnold presses, 4 sets of 20(10 each arm) alternating front arm raises, 4 sets of 10 lateral arm raises, 4 sets upright rows, 4 sets of heavy dumbbell lunges)
Do that for 6-8 weeks, take a week off, rinse and repeat.

Power cleans, power cleans, power cleans, and when he is done with that, do some hip flexibility stretches and then finish off his workout with some power cleans.
