The Inventors of The Stack System
Dr. Sasho MacKenzie works with the world’s best coaches and is considered the leading “golf biomechanist”. Thanks to him, golf has a scientifically sound basis in terms of movement and training.
Sasho’s core competencies lie in the training and biomechanics of golf swings – especially when it comes to optimising them for speed. The Stack System allows the scientific principles and training methods to be delivered directly to you. And with the same system used by the world’s best coaches and tour players.
Sasho has published over 20 scientific articles in peer-reviewed journals. He is booked for lectures worldwide. Sasho also works in other sports such as baseball. He is a professor of sports biomechanics at St Francis Xavier University in Antigonish.
Marty Jertson has been an engineer at PING for 17 years and is the co-founder of the Stack System. He was instrumental in the development of the successful G30 and G410 series, as well as the world-famous iPING putting app. He has registered a total of 125 patents.
Marty has played in a total of 6 major tournaments, most recently the 2020 US Open. So he’s not just a master of his craft in the lab. His passion is to develop solutions for the daily problems of us golfers.
The founders of SwingSpeed.eu
Jonas Weiss and Florian Achenbach have founded Europe’s leading online shop for exclusive golf clubs, ExactGolf.com. ExactGolf is the largest retailer of Miura golf clubs in Europe. These clubs have been manufactured for decades in their own workshop in Bavaria, Germany – precisely fitting and exactly according to the player’s requirements.
WeissGolf is one of the leading brands for club fitting and welcomes players from all over Europe. WeissGolf is the first True Spec Golf partner in Germany. True Spec Golf is one of the few suppliers who source all components individually and only as originals. All clubs are fitted and built to exact specifications by True Spec themselves and not by OEMs.
Out of the passion for the sport and the vision to make the game of all golfers easier, the two decided to found SwingSpeedTraining.eu and to distribute the best training aid for swing speed in Europe.
