The concept of overspeed training is abuzz today, among elite amateur and pro golfers alike, for good reason: science has proven that over speed training works. However, generating speed in the golf swing is largely dependent on solid mechanics which most overspeed training products and programs DO NOT TEACH! SlingShot is more than just an overspeed trainer, it provides audible and physical feedback through-out your entire swing that allows you to see real game improvement. This feedback is the key to helping you improve your balance, tempo, & timing to produce maximum club head speed. Additional benefits include improved flexibility and power. Warm up, condition and overspeed train with one club that you can adjust to four different weight settings. SlingShot’s intuitive design means you can work with any overspeed training or exercise regimen you personally choose.
