The Savant of Speed
The Stack System provides dynamic programming directly from golf's leading biomechanist. Speed training secrets previously reserved for Tour players, now available to you.
5 CNC milled Stack weights combine with a custom engineered shaft & hardware to create 30 unique combinations for unlocking dynamic variable inertia speed training.
Programs designed in the lab - and proven on Tour - that respond dynamically as you level up your speed.
You'll need a speed tracking device to get started. We prefer the PRGR Black Pocket, but TheStack is compatible with other options. See the list of options in the 'Compatible Devices' Tab
Guided Programs Based On Your Initial Baseline
Initially, each golfer is piloted through a series of swing speed tests to generate a force-velocity profile of their current swing. Qualitative data is gathered on perceived strengths and weaknesses related to generating clubhead speed.
Based on individual comprehensive baseline data, TheStack App’s artificial intelligence (A.I.) algorithms provide a list of customized program options. The program list is rank ordered starting with the program that has the greatest likelihood of increasing clubhead speed over a 6 to 10 week period, which equates 18 to 24 training sessions.
Timers Tell You When To Swing, And When To Rest
TheStack App provides customized variable inertia speed training - the most efficient way to increase your clubhead speed. The algorithms that power the dynamic programming come from years of research by leading sport scientist, Dr. Sasho MacKenzie. TheStack App is available on iOS and requires iOS 13.0 or later.
Enter Your Speed Data Hands-Free
Using TheStack System’s voice entry technology, enjoy hands-free data collection during training sessions, by simply dictating your speed readings into the App. The hands-free data capture feature even works when wearing AirPods or earbuds. If you are training with a coach or friend, numbers can be keyed.
Track Your Progress With Custom Metrics
TheStack has streamlined your performance variables into 4 key metrics. Stack Speed, Speed, Distance Potential and Grit Score. Learn More
