So, I'm giving some private classes to an Kid who has autism. He is 16 y/o. We have good communication but he is very, very passive and his mother would like to get him to be more aggressive. I've been trying to teach him how to punch correctly but it's not really working. He won't get things like footwork or keeping your hands up or even punching with your knuckles. He keeps going back to hitting with the palm of the hand. Kind of like girly punches. I'm aware I'm not going to build a Muay Thai champion here but this is done for the benefit of excursive and if he learns some aggression in the way them great. I was wondering if anyone here has some experience working with people like that and can give me some tips.
