TheStack Golf Speed Training System

TheStack is golf's #1 speed training system, with the average user gaining 10.1 mph of club head speed. The system pairs the training club, comprised of precision hardware with 30 unique mass combinations, with the app, which acts as a personal trainer with customized speed programs that change based on your performance. 

The app was developed by Dr. Sasho MacKenzie, golf's foremost biomechanist, who specializes in speed generation training. It uses the same tools, techniques, and nuances he uses to speed train Tour players.

To get the most out of The Stack System, you'll need a compatible iOS or Android device and a radar capable of measuring swing speed without golf ball contact.
