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.
Power Stairs
In the power stairs, implements are moved up a staircase. For training purposes, these can be performed with a tire or box.
Begin by taking the implement with both hands. Set your feet wide, with your head and chest up. Drive through the ground with your heels, extending your knees and hips to raise the weight from the ground.
As you lean back, attempt to swing the weight onto the stairs, which are usually around 16-18" high. You can use your legs to help push the weight onto the stair.
Repeat for 3-5 repetitions, and continue with a heavier weight, moving as fast as possible.
Verdict
Both exercises target the hamstrings. 90/90 Hamstring is a beginner exercise using bodyweight, while Power Stairs is intermediate and uses other. Choose 90/90 Hamstring if you're looking for a more accessible option, or Power Stairs for a greater challenge.
