Dynamic Training

TheStackApp

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.

       If I am looking for a training aid Golf Swing Systems is my first option. I bought TheStack several years ago and upgraded to the Stack Radar. Super fast delivery and great advice (big shout to Alex).

      After much deliberation and considering various companies, I finally decided to purchase a golf simulator bundle from Golf Swing Systems (GSS), and I couldn't be happier with my choice! The package I received was nothing short of amazing, and the price was exceptional. Throughout the entire process, the communication regarding my order was fantastic, and the assistance I received was truly 5-star. I honestly can't recommend this company enough for anyone looking for golf simulator solutions. A special commendation goes to Tracey, the Warehouse Manager, who went above and beyond to provide outstanding help. Her dedication truly made my experience even better!

      I recently bought a launch monitor for my sim from the guys at GSS. I had an issue with the unit (manufacturer issue). I dealt with Alex and Tracey, absolutely top class customer service. I had a replacement unit to my door within a day. You can really tell how good a company is when the customer has an issue, most companies are great until they get your cash and then are very slow to respond etc. when you raise a complaint. I felt Alex was genuinely going out of his way to make sure I was happy with my purchase and didn’t try fob me off when I raised concerns. Tracey was really efficient and had my old unit picked up and new unit delivered within a day. I’m delighted with my purchase now and look forward to dealing with GSS again as I continue to build out my sim room!

      Masters in customer service - bought TheStack from them a month ago and had a query about the pricing. Alex messaged me back within 10 mins (before 7am) and made sure I got an extremely competitive deal. Would 100% recommend the team, particularly Alex.
