As a power source your legs are very important, but not in the way you may think. The fact is your legs do not provide your swing with power directly. Power comes from your club head speed, and since your hands and arms hold the club, they are the only things that can directly make the club move faster. You legs however, are the principle multipliers of power and without them your speed would be significantly decreased. Your legs are used as “anchors.” The more you anchor them, the tighter you can wind up in the back swing and then uncoil from the ground up in the down swing. To feel this set up golf ball and then push your feet into the ground. You will most likely feel the inside muscles of your thighs and calf muscles tighten. Your feet should be firmly planted. You can also try this example. Sit in a chair and make a golf swing. You may think you are not using your legs but in fact you are using them the correct way. Now pick your feet up off the ground and make a swing. Kind of hard isn’t it? Plant your feet, push your legs into the ground, and wind up that swing to produce power!
