Lie on your back with your palms facing down and your hands under your hips. Keep your feet straight and in the air. Tighten your abdomen as you slowly lower your right leg toward the bed until it is parallel to the surface of the bed, keeping both legs as straight as possible.
Bring the leg back up to the starting position without touching the bed. To complete one repetition, repeat with the opposite leg.
Perform 20 repetitions.
