I have been trying to increase my swing speed for years, here's how. If you go to www.swing-speed.com you can see the instructions using their $280 device. I can do the same exercises with a resistance band I already own. My current swing speed is average 96 mph and my average carry is around 230 yards. The PGA tour average is 113 mph and 275 yards. I will do these exercises over the summer and report back my progress.
