Hey ya old fart! Haha, I do remember you. This is a great question and quite refreshing to talk about here. Of course, at this stage of the game, make sure that you guys keep it fun. You’re a lucky man, having the opportunity to give him the gift of weight lifting. If we are lucky, this is a gift that he will continue to enjoy well after you and I are gone from this earth. As for plans, I think you are on to something. Get the basics down to build a foundation.You could stick with just these lifts or you could add in some additional lifts for fun, like adding in 1 exercise each, maybe 3 sets, shoulders, bi, tri, and abs. I would make sure to keep the workout to an hour. So maybe start with the big movements and then work your way down. I like the Mon, Wed, Fri set up. This is good. If that just seems like too much in real world exercise, pull them out and stick to the basics you already plan to do. And as for diet, you can teach him the importance of diet in the sport but I would not put him on a strict diet at this stage.
