Instructions
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.
Glute Ham Raise
Begin by adjusting the equipment to fit your body. Place your feet against the footplate in between the rollers as you lie facedown. Your knees should be just behind the pad.
Start from the bottom of the movement. Keep your back arched as you begin the movement by flexing the knees. Drive your toes into the foot plate as you do so. Keep your upper body straight, and continue until your body is upright.
Return to the starting position, keeping your descent under control.
