TEACH HIM HOW TO STRETCH!!! If he lifts too much and does not work on keeping his flexiblity it will do him no good except to look good in a tank.
There are a ton of guys who are bulked up and look stronger than an ox, but they have so little flexibilty they can't swing a baseball bat, or a golf club or even draw a compound bow.
Flexibilty is so important, I dare so even more important than brute strength. A good balance of the two is best. Remember toom, that at that age, bone structure and tendon structure is changing and not fully developed. A friend I know lifted like crazy in 7th grade. Got pretty big, then grew like 7 inches in two years and he had tons of problems cause he lost his felxibilty cause he muscles were too tight. Ruptered a knee tendon just jogging the bleachers.
Yes, an extreme example, but at that age caution is important.
