In this video, Avera Golf Fitness Specialist Dick Bartling gives you the side plank exercise that will help improve your lateral core stability for the golf swing. Move to the ground so that one side of your body is along the ground. Raise the body by anchoring your arm on the ground, pushing yourself up. Try to stay level and straight and hold this position for up to 60 seconds without too much shaking or sagging. Switch to the other side and hold again for up to 60 seconds.
