The shoulder scissors move is like a sliding elbow plank; in one fell swoop, you'll work your triceps while leaning out your abdomen. All you need are two small towels to place under your elbows (or paper plates or gliders if you're on a carpet). Here's how it's done!

• Begin in an elbow plank position with a small, folded towel under each elbow. Keep your elbows directly under your shoulders, back flat (neutral spine) and core tight!
• Slide your right elbow forward until your arm is nearly fully extended. With control, bring the right elbow back to center.
• Repeat on the left side. This completes one rep. Start with 10 reps and work your way up to 20!
• If you need to modify, you can drop to your knees (while keeping your back straight and core tight); you'll still work the core and triceps!
