A Quick Exercise For Lean Legs

When you’re at the gym and can’t imagine doing yet another squat or lunge, give this simple toning exercise a try. The lying leg curl is designed to isolate your hamstring muscles (the ones that run along the backside of your thighs). Plus, it’s a nice break to some of the more intense muscle-building moves, and it’s effective.

Crunch Gym trainer Allison Berry shows us how to execute the curl just in time to break in those Mila Shorts for the summer . Scroll through for a quick demo so you can try it the next time you're at the gym.
