This wall Pilates move literally elevates the classic glute bridge, amping up the engagement of your glute muscles and core.
Sit about one foot away from a wall, and lie down on your back. Place your feet flat on the wall so your legs are in tabletop. This is your starting position.
Press your feet into the wall to engage your hamstrings and glutes, and lift your hips off the floor. (Make sure not to arch your back.) When your body forms a straight line from shoulders to knees, lift your heels off the wall to balance on your toes, and do a calf raise.
Reverse the movement, lowering your heels to the wall and then your hips to the floor to return to the starting position. That's one rep.
