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.
Good Morning
Begin with a bar on a rack at shoulder height. Rack the bar across the rear of your shoulders as you would a power squat, not on top of your shoulders. Keep your back tight, shoulder blades pinched together, and your knees slightly bent. Step back from the rack.
Begin by bending at the hips, moving them back as you bend over to near parallel. Keep your back arched and your cervical spine in proper alignment.
Reverse the motion by extending through the hips with your glutes and hamstrings. Continue until you have returned to the starting position.
Verdict
Both exercises target the hamstrings. 90/90 Hamstring is a beginner exercise using bodyweight, while Good Morning is intermediate and uses barbell. Choose 90/90 Hamstring if you're looking for a more accessible option, or Good Morning for a greater challenge.
