Ok first up I would say to leave out any supps. Providing him with supps will just set him off on a bad track. He needs to know there is no magic pill, and there is nothing that will replace a good diet. Get him started with that mentality. If he's just looking to get better at sport I wouldnt go crazy with a diet just make sure he is eating 3 or 4 decent meals a day, sweets and biscuits and crisps and stuff could be eaten occasionally depending on how likely he is to get fat. You dont wanna make it boring for him, kids eat sweets and at 13 he shouldnt be worrying about cravings or whatever. But keep it limited try not to let him eat like shit all day long.
First few weeks I would have him train once every 3 days or so. 2-3 sessions a week. I would also spend a long time working his form on deads, squats, benchpress, military press etc. No need to go really heavy even when he has learned good form but I wouldnt just get him doing cables and arm bands and stuff...
You could do squats, benchpress, chins one session then military, deadlifts, dips another session. Throw some abs in after one workout then some grip work after the other.
keep it simple and fun for him imo...
but ultimately it comes down to you as the parent to make the decision if he is old enough to lift weights yet
