90/90 Hamstring
- Lie on your back, with one leg extended straight out.
- With the other leg, bend the hip and knee to 90 degrees. You may brace your leg with your hands if necessary. This will be your starting position.
- Extend your leg straight into the air, pausing briefly at the top. Return the leg to the starting position.
- Repeat for 10-20 repetitions, and then switch to the other leg.
