Hips and thighs
Lie on your right side with right arm resting on floor, elbow bent. Place left hand on ground in front of your body for support. Extend legs with knees slightly bent or straight, and stacked one on top of the other. Lift top leg through full range of motion, then lower to hover just above the floor in front of bottom leg. Do not allow lifted foot to touch floor between reps, and complete all reps before switching to opposite side to equal one set.
Challenge yourself: Cross top leg over bottom leg, and place foot flat on the floor. Then, raise and lower bottom leg about a foot without allowing it to touch the ground for an inner-thigh workout.
