He hates team sports, won't participate (it's too socially complicated/ASD).
He doesn't want to go running or biking (he's good at this).
He won't even go and play catch (v.good at) with his sister.
He is resistant to all forms of exercise. He won't even do his physio exercises any more.
He was is a sports club but he is too old now. He used to do martial arts but he stopped a while ago and won't go back.
I've had his teacher on to me because he hasn't completed a single PE lesson this term (his neck hurts, his ankle hurts, his knee hurts etc etc)
