Today I’m speaking with Dr. Sasho MacKenzie, co-founder of The Stack System, an innovative training tool that applies principles from the world of track and field to improve your clubhead speed in an efficient and measurable way. “I like to use the Stack to reinforce positive swing mechanics,” says Dr. MacKenzie. Listen in as he explains how the The Stack System targets the force of the grip to measure swing speeds, and how its personalized app offers real-time feedback and actionable data to the user, making the program an indispensable training companion. We then explore success stories and the transformative potential of The Stack System. With the top 5,000 users gaining an average of 12 miles per hour, and a recommended gain of 6-10 miles per hour from the 6-week foundation program, we discuss what golfers can expect from using the system over time. In the same vein, Dr. MacKenzie also addresses the minority of users who may struggle with lack of control over their swing speed, particularly at max-level, offering advice and solutions for overcoming their limitations. We then talk about how The Stack System can be applied in various training environments and climates. We focus especially on how it can be beneficial for female golfers looking to add aggression to their game. Finally, Dr. MacKenzie and I discuss the program’s Stack Putting System and how its progressive training structure can help you minimize your putting biases over time, whether you’re struggling with speed or direction.
