5 Exercises For Stronger Arms and Shoulders

The up-down plank is great for not only your arms and shoulders, but for core stabilization as well. It targets your shoulders, chest, triceps, obliques, and abs. Rolle suggests performing this movement from your knees if you are a beginner or need a modification.

• Start in a low plank position with your elbows directly under your shoulders.
• Replace your right elbow with your right hand and your left elbow with your left hand, ending in a high plank position.
• Replace your right hand with your right elbow and your left and with your left elbow, ending in a low plank position.
• Repeat for 10 repetitions, alternating the starting hand.
