The Stack System is an advanced, AI-powered golf speed training tool designed to systematically increase a golfer's clubhead speed and driving distance. Created by leading sports scientist and biomechanist Dr. Sasho MacKenzie alongside Marty Jertson, this highly structured system moves away from traditional, generic speed sticks in favor of highly personalized, data-driven training.
App & Hardware Info: Every brand-new system includes the highly engineered training club, 5 stainless steel weights, and 1 year of free Premium App Membership. A compatible iOS device and a swing radar (like the PRGR unit) are required for tracking and are sold separately.
