Two moves to longer drives

Your core the mid-section of your body encompassing the abdominals, backside and lower back is literally central to a powerful golf swing. Being strong here will enable you to maintain good alignment throughout your swing, while weak ab muscles can put stress on the lower back by not providing enough support for the spine. "The roots have got to be strong in order for the branches to be strong," says Josh Salzmann, Ernie Els' personal trainer. You don't need a gym or equipment to strengthen your core simply do the exercises below twice a week. For further fitness details check out Josh's website at truthaboutfitness.com.

ABDOMINAL CRUNCH WITH TWIST WHY IT'S GOOD
