You’ve likely heard of the SuperSpeed Golf Training System, three differently weighted club shafts that utilize overspeed training to increase your swing speed and thus distance.
If you’re skeptical of spending big bucks on the system, but still interested in trying an overspeed training regiment out, you can use the clubs you already have to do so — a club-less shaft or your driver held upside down will act as your lightweight, your 5-iron will act as your middleweight and your sand wedge can be your light-weight solution.
