Execution
1. Find a rail, beam, or stable couch to wedge your feet under. Kneel on top of a pillow or
folded towel to reduce pressure on the knees.
2. With an upright trunk, lower the body under control while keeping the glutes tight,
making sure not to bend forward too much at the hips or allow the pelvis to anteriorly
rotate too much.
3. At the bottom of the movement, catch yourself in a push-up position and spring back to
starting position, using the shoulder and arm muscles for assistance but attempting to
maximize the torque on the knee joint and trying to rely on the hamstrings for
movement production.
