Sitting Single Leg Hamstring Stretch
If you want to run faster you want your hamstrings to work. If you want to be able to walk after running, you need those hamstrings to work! Stretch out those hamstrings before and after your run to keep yourself healthy and speedy.
Start in a long sitting position with one leg out to the side and the other stretched out in front of you. Your leg out to the side should be bent with your foot tucked in to your other knee. Reach out for your extended leg and feel the stretch on the back of your leg. Hold that position for 30 seconds and don't bounce in this position. Repeat on the other leg and get yourself running.
