What is The Stack System?

Before you start your training with The Stack, it’s important to first understand how the system works. In the video below, Sasho explains the core concepts and basic operational principles of the system.

Backed by Science

Over a decade of research and development has gone into The Stack System, and the final product is a precisely manufactured variable inertia speed training system that adapts to every golfer to maximize their speed gains.

TheStack's interchangeable weights and guided programs train the user's neuromuscular system to move the club faster, which will increase ball speed and driving distance.

Built on Data

Every swing taken in the app is recorded, logged, and used to guide our dynamic AI algorithms to recommend the most effective program to every user at any given time during their training.

All of this data is accessible to the user in TheStack App, which allows them to view personal bests, improvement over time, and how their swing speeds measure up to similar golfers.

Validated with Results

Unlike other speed training companies, our comprehensive database of training swings allows us to share irrefutable evidence that The Stack System works.
