I am always looking for quick ways to work my arms, and this move is great for those commercial break moments as well as downtime between sets of leg work at the gym. The side arm push-up tones triceps, deltoids, and the outside of your chest. Keeping your core engaged will also work your waist. Nice bonus!

Learn the details.

• Lie on your right side with your knees and hip bent to 45 degrees. Wrap your left arm around your waist and place your left hand in front of your right shoulder with your fingertips parallel to your body. Keep your waist lifted with energy shooting out of the top of your head.
• On an exhale, press left hand into the ground and push yourself up, straightening the left elbow. Inhale, and slowly lower yourself back to starting position.
• Do three sets of 10 to 15 reps.
