My experiences in this department are numerous. The most important thing is that he understand how and when to weight lift. His technique is vital. Use very light weight for at least a month, increasing very little as time goes on. The reasons are many, but most importantly obviously we don't want him to get hurt, secondly, there's no sense throwing up a lot of weight and then being sore for the next week, hence discouraging him from lifting. Also, getting a set schedule is important. Something like Monday and Friday upper body and Wednesday lower, and maybe two or three days of cardio, but I'm sure his team will help with that. I wouldn't go more than three days of lifting a week for starters, unless he takes off with it. Also, please check out websites, I know there are thousands of them on this topic.
