Set the barbell rests on the power rack to knee height, and lay a barbell across them.
Position a bench horizontally behind you.
Add the desired weight to each end of the barbell, distributed evenly, and secure in place with a pair of barbell clamps.
Sit on the bench with the barbell resting on your thighs.
When ready push your toes into the floor as if trying to lift your heels against the weight of the bar.
Hold this position for the duration as instructed by your therapist.
