The third level of exercises also promotes a stable address position. Place the Swiss ball against a wall and assume a semi-horizontal position over it with both arms extended onto the ball to support your weight (above). Remember to maintain a good spine alignment through the neck, shoulders, trunk and pelvis. This will allow a better axis to rotate around which is essential for a consistent, dynamic golf swing. To advance this drill, keep your toes on the ground then start to ‘bounce’ through your calves so that your heels are moving up and down. This will allow your lower abdominals to ‘fire’ in the golf swing. Repeat the exercise twice, for 15 seconds apiece. You can progress this drill further by taking the ball away from the wall and supporting yourself entirely.
