It’s time to bridge into September. This new fitness challenge will work your glutes, lift your butt, engage your core, and strengthen your hamstrings with one simple move. To perform a bridge, lie on your back with hands by your side, palms up. Bend your knees with feet flat on the floor. Engage your glutes and push through your heels to lift hips straight off the floor. At the top of your bridge, glutes are highly engaged, but back is straight at an angle. Lower hips and repeat the movement. Get ’em done before you get out of bed, while you’re watching TV, or throughout the day. Just save, print, or pin the image below and take on the September challenge!
