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 customized 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.
Once a program is selected, TheStack App continues to function as a personal trainer, guiding scheduled workouts and tracking stack weight, rest, recovery, and performance data. The tracked data entered during each workout is constantly utilized by TheStack’s A.I. algorithms to adjust and individually optimize subsequent Stack workouts, maximizing clubhead speed gains.
Upon completion of a program, each golfer goes through a Progress Check, to quantify speed gains. This data is then used by TheStack’s A.I. to rank order your next training program options. The more you train with TheStack, the more individually tailored the programs become!
TheStack's A.I. algorithms were formulated following years of research by leading sport scientist, Dr. Sasho MacKenzie. The same science used to speed train the world’s best is now available to all golfers.
Library of A.I. Programs
The Foundation Most popular
The Foundation is the meat-and-potatoes speed training program, which has consistently delivered gains to a wide range of golfers with varying levels of speed training experience. It’s designed to ease the beginner into speed training. It is not uncommon for golfers to repeat this program.
The Foundation consists of 18 sessions and takes approximately 6 weeks to complete.
Full Speed Spectrum
Full Speed Spectrum aggressively targets the neuromuscular system to stimulate changes in both the force and speed components of the power curve. This program is well-suited to golfers who currently require a balanced increase in the ability to both apply high levels of force and move quickly.
The Full Speed Spectrum consists of 24 sessions and takes approximately 8 weeks to complete.
The Heavy Hitter is particularly helpful for the athlete wanting to smooth out tempo and improve functional range of movement of key power producing muscles. The initial focus is on using Stack masses that exceed the inertia of the driver. The Heavy Hitter is ideal for golfers wanting increased control of their driver’s movement.
The Heavy Hitter consists of 24 sessions and takes approximately 8 weeks to complete.
Particularly helpful for golfers whose clubhead speed fails to reach expectations relative to their level of strength. The Neural Drive program is also effective for the golfer who struggles with the concept of maximum effort swing.
Neural Drive consists of 24 sessions and takes approximately 8 weeks to complete.
The Neural OverDrive is a natural progression for golfers who benefited from the Neural Drive program. There is continued emphasis on contraction speed, with the increased complexity of adding a lead-foot step during many of the sets, placing enhanced focus on a coordinated transition.
Neural OverDrive consists of 24 sessions and takes approximately 8 weeks to complete.
Trail Arm Enhancer Single Arm Program
The Trail Arm Enhancer is designed for golfers whose trail arm is the limiting factor in generating clubhead speed. The focus is on pressing the trail arm to produce speed without allowing the lead arm to hide the trail arm’s limitations, as can happen in regular two-handed swings.
Trail Arm Enhancer consists of 24 sessions and takes approximately 8 weeks to complete.
Lead Arm Enhancer Single Arm Program
The Lead Arm Enhancer is designed for golfers whose lead arm is the limiting factor in generating clubhead speed. The focus is on pressing the lead arm to produce speed without allowing the trail arm to hide the lead arm’s limitations, as can happen in regular two-handed swings.
Lead Arm Enhancer consists of 24 sessions and takes approximately 8 weeks to complete.
Library of Creative Programs
Cruiser is a flexible program designed to be used in-season or during busier times. You’ve made some gains but will have limited speed training time in the coming weeks and want to maintain your speed.
Before starting each session, the app will give you the option of completing an 8-, 15-, or 25-minute workout. You also set the number of sessions in the program.
Flex is a highly accommodating program that is provided for Stackers who are interested in exploring various workout options within a single program. Before starting each session, the app will give you the option of completing an overload, overspeed, or mixed session lasting 8-, 15-, or 25-minutes. You also set the number of sessions in the program.
