3. Ball to Knee Leg Raise
“This is an excellent exercise to improve your core strength, balance and coordination—it’s a brain workout, too,” says Phelan. “And, as an added benefit, you will feel this in your shoulders.”
A. Stand with feet parallel, hip width apart and knees slightly bent. Hold the ball in both hands above your head with elbows slightly bent.
B. (Shown) Raise your left knee to hip height, keeping the thigh parallel to the floor as you lower the ball to touch your left knee. Keep your back straight and your chest lifted.
C. Return to starting position, and do the same move with your right leg. Do 12 repetitions.
