Stability Ball Deadbug

WHY? This exercise will help strengthen your core and help with your trunk stability in the golf swing.
Lie on your back with your knees bent at 90 degrees and hold a stability ball between your hands and knees.
Slowly extend one leg and the opposite arm toward the floor, keeping your lower back pressed into the ground.
Bring your arm and leg back to the starting position and repeat on the other side.
