How to do the 90/90 Hamstring
- 1
Lie on your back, with one leg extended straight out.
- 2
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.
- 3
Extend your leg straight into the air, pausing briefly at the top. Return the leg to the starting position.
- 4
Repeat for 10-20 repetitions, and then switch to the other leg.
Log it, see it on your body.
