Does he have msn? Or Email? If he does get hold of him and talk to him some people just dont wana be in shape if he doesnt want to from the start its probs never gonna go well but if it does and u get healthy eatin and exercise in to his daily routine at a young age its gonna stick
Try to motivate him show him the results that you had and tell him how much fun it is then build it up, train him over the internet like you would to any bro on EF, like saibot does to me Iv never met him but he's like a personal trainer to me lol, then if u see him twice a year, say every 6 months you will be able to see how he is getting on. Just help him out even if u dont want him lifting at all try to introduce him into sport and shit. All the cals he is taking in will probably mean he find buildin muscle quite easy, yes? That will motivate him if he sees good gains even if he just does bodyweight circuits and shit... idk depends what you want him to do
Lol I hope so with the competitions.. Bk's vids really inspired me lol but idk if its gonna happen.. it all sounds too good to be true...
