Lift your buns, tone your thighs, strengthen your back, and sculpt your abs (they have to work even harder to stabilize your torso with one leg in the air) with this bridge variation.
How to do it: Lie faceup with your arms pressed against the floor by your sides, knees bent, and feet flexed (only your heels should touch the ground). Extend your right leg up to the ceiling as straight as possible, keeping your foot flexed. Tighten your abs, press down through left heel, and lift hips as high as possible. Lower hips to lightly tap the floor. That's one rep. Do up to 3 sets of 15 repetitions on each leg.
