Start on all fours with your hands directly under your shoulders and your knees directly under your hips.
Slowly slide your knees further apart so they are wider than your hips.
Begin to shift your weight backward as you move your glutes back toward your heels. You should feel your glutes start to work as you shift backward and hold.
Shift your torso forward again to return to the starting position.
This counts as one rep. Repeat two sets of 10 reps.
