Increase your swing speed up to 25 mph ( http://www.swing-speed.com ) or more by taking advantage of your natural, built-in speed multiplier. There is a lever hidden inside every golfer that multiplies the speed of the hips 25 times at the club head. This means that just a 1 mph increase in hip speed can increase your swing speed 25 mph. Our video shows how every golfer can increase their hip speed to get that extra 25 mph in swing speed.
