This Trainer's Lower-Body Workout Is So Good, It Only Takes 11 Minutes to Do

• Start lying on the ground with your heels in the foot cradles, your feet underneath the anchor point, and your legs fully extended. Your arms should be at your sides, palms facing down.
• Engage your core, and with control, pull your heels towards your glutes. As you bring your heels toward your glutes, simultaneously lift your hips up higher. Keep your upper back on the floor.
• With control, straighten your legs without dropping them to the ground. This completes one rep.
• Repeat for 30 seconds.

Take one minute of rest and then repeat for a total of four rounds.
