No Need to Stand! Work Your Butt With These Floor Exercises

To keep the pelvis stable in this position while moving your legs, you really need to engage your glutes.

• Lie on your back with your hands by your sides, with your heels about 12 inches from your pelvis. Press your heels into the floor to come into a bridge position with a neutral spine.
• Press your right heel into the floor, and keeping your left knee bent, raise your left leg until your hip is at 90 degrees. Lower your left leg down, pressing through your right glute so your pelvis doesn't drift to the floor as you lower your leg. This completes one rep; switch sides and lift your right leg for your second rep.
