The Stack System provides dynamic programming directly from golf’s leading biomechanist. Speed training secrets previously reserved for Tour players, now available to you.

Dr. Sasho MacKenzie, Co-Founder

Golf’s foremost biomechanist, Dr. Sasho MacKenzie is the research practitioner behind the world’s top golf coaches – his work and theories have driven a scientific, evidence-based revolution in golf instruction and movement training.

Sasho’s area of expertise is the training and biomechanics of speed generation. The Stack System allows Sasho to share his research findings and training wisdom directly with you, using the same tools, techniques, and nuances that he uses to speed train Tour players he has consulted.

Variable inertia speed training is the most efficient way to increase speed.

Programs & Training

TheStack is a personal swing-speed trainer for golfers.

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 customised 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.

TheStack App provides customised 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.

Here is how it works…

Dynamic Training Programs

TheStack App functions as your own personal trainer, guiding you through scheduled workouts while tracking Stack weight, rest, recovery, and performance gains. This information allows future workouts to be adjusted behind the scenes, so your training is optimized to maximise clubhead speed gains.

Baseline Session

Similar to working with a personal trainer, you are guided through a detailed intake session. Qualitative data is gathered on perceived strengths and weakness related to generating clubhead speed. You’ll be coached through a series of swing speed tests to generate a force-velocity profile of your current swing. This data informs A.I. algorithms which create custom programming options.

Programs

Following the Baseline Session, TheStack App provides a list of customized programming options. The list is prioritized specifically for you by greatest likelihood of increasing clubhead speed over a 6 to 10 week period (18 to 24 training sessions).

Training

During each training Session, TheStack App coaches you through each swing – seamlessly guiding stack weight configuration, swing intent and rest for each rep and set.

Hands-Free Data Collection

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.

Workout Summaries

Detailed post-workout data review enables you to verify and, if needed, make any changes to speed data before syncing to the cloud.

Tracking and Sharing Metrics

TheStack App tracks key performance metrics such as Stack Speed, Distance Potential, Clubhead Speed and Grit Score. Easily share your progress and gains to your favorite social media platform.

Progress Checks

After completing a training program, TheStack App re-assesses your gains with a Progress Check, from there reformulating your next program. Data captured along the way improves the intelligence of TheStack algorithms through A.I. techniques.

Cloud Storage

Training data is stored securely in the cloud. Whether you get a new phone or want to login from another device for your next training session, everything works seamlessly.

Radars Devices and Integration

Stack training requires a radar that can measure swings without ball impact. Not all radar devices have this capability. This page will always be up to date with radars that can capture non-impact swings.

At The Stack System, we analyze nearly all radar devices that track training swings and TheStack App factors out any bias, or systematic error, in speed measurements that are associated with our hardware design. What does this mean to you? If your radar measures with a bias, our smart algorithms adjust for it and accurately calculate your eSpeed and Distance Potential regardless of which device you are using.
