text: how can i strengthen my knee? i'm 21 and play basketball and just starting to do some muy thai boxing. my knee just recently started giving me some problems. is there any way i can strengthen my knee in particular? you can do hamstring curls, you knee in particular is not a muscle, so you cant just strenghten it, but if you do the curls and other hamstring/quad exercises, strengthening the muscles around the knee will help because they are what supports the knee
