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.
Precision Hardware
5 CNC milled Stack weights combine with a custom engineered shaft & hardware to create 30 unique combinations for unlocking dynamic variable inertia speed training.
Dynamic Training
Programs designed in the lab - and proven on Tour - that respond dynamically as you level up your speed.
Tracking Speed
You'll need a speed tracking device to get started. We prefer the PRGR Black Pocket, but TheStack is compatible with other options.
