Strong Arms in Just 6 Moves

4. Slide Out and Ins with Plates: Think of this as a tricep push-up. Get in a push-up position on your knees with your plates under your hands. Slide your right arm out while bending your left elbow. Keep that elbow tucked into your side and really reach that right arm out. Be sure to keep your body in a straight line, no saggy hips! Slide that right arm back in and push your left arm straight so you are in starting position. Alternate arms and do as many as you can in 60 seconds.
