First make sure you are following the right steps. Sit then swing your arms to your ears and then jump into the back handspring. Any other order will not allow you to push completely through your toes and get straight legs. The other common problem is your knees come apart when you push off so get a rubber band to hold them together so you have to push through your toes. Also you can put your feet halfway on a panel mat or piece of foam floor which will make your toes leave the ground last thus improving your plyometrics.Make sure you are stretching only through your shoulders not in the middle of your body during the handspring. Sometimes it is a need for the whole power base glutes, hamstrings, and calves strengthening. Again the exercises on the website are available.
