7. Side Leg Raises
Lie on one side with your legs stacked. Bend the bottom leg for support. Straighten the top leg and raise it to 45 degrees. Hold for 5 seconds, lower and relax briefly, then repeat 10-15 times. Switch sides and start over. Want to try a bit of a different spin on the move? Point the toe of your upper leg slightly toward the floor as you raise it.
