TheStack is a swing speed trainer co-created by biomechanist Dr. Sasho MacKenzie and Ping engineer Marty Jertson. This system helps golfers increase their swing speed and distance with a personalized training regimen. Paul, a professional golfer with a plus-handicap index, tested TheStack for four months with impressive results. Charts show an 11 mph increase in driver speed and over 30 yards of total carry after just eight training sessions.
The beauty of TheStack is that even with inconsistent training, significant gains can be achieved. The system includes a hardware bundle with milled Stack weights and a highly engineered training club. The app provides guided workouts, custom speed metrics for tracking progress, and voice entry technology for hands-free data entry. The system also includes access to Stack Putting, which is currently in beta, and enables training and tracking for up to five users under one login.
Paul experienced noticeable improvements in his game after incorporating TheStack into his routine. His ability to hit shorter clubs into par 4s from the same tee box and conditions showcased the effectiveness of the system. Paul’s distance off the tee increased, and he saw substantial gains in his ball speed and overall performance. With TheStack, the potential for further improvement and reaching new milestones in his game seems within reach.
