If the poster really wants to listen to you and train in a gym then you have done him a big favour, he will get fit, learn some new skills and may even deter the bullies from ever touching him. If the worst comes to the worst at least he will be prepared and be thankfull that there was someone out there that offered him advice.
I would be happy to give advice to ppl about street fights as long as it doesnt start as " This guy fucked my girl" or "I hate this kid at school, how can i bash him".
