Here are some exercises to help you strengthen those hamstrings:
1. Hamstring Hold
a. Lie on the floor with feet on the ball and hands by the sides
b. Tighten the stomach and raise the hips off of the floor so they are in line with feet and shoulders

2. Hamstring Curl- Repeat steps a and b from exercise one.
