Check out Women's Health's FitGIF Friday every week for fun and challenging new moves to make your sweat sesh really count. Here's this week's exercise:

Kneeling overhand alternating press: Not only is this press a great shoulder workout, it's awesome for increasing your stability. When you alternate the press, you're challenging each side of your body's balance individually. To take things a step further, by performing the press on your knees rather than your feet, your core has to work extra hard to keep this move in perfect form.
