2. Bend one knee at 90 degrees and lift the leg off the floor.
3. Squeeze the glute to drive the heel toward the ceiling until thigh is parallel to the floor.
4. Pause at the top to maximize contraction.
5. Lower the leg slowly back to the starting position without touching the floor.
6. Switch sides after completing reps on one leg.
