The Stack System, a leader in golf performance training, has partnered with the Junior Golf Association of Arizona (JGAA) to launch TheStack x JGAA, an initiative designed to help junior golfers develop speed, consistency, and overall performance as they advance in the game.
The Stack System, based in Phoenix and Co-Founded by JGAA Alum Marty Jertson, is known for its dynamic training programs, built in the lab and proven on Tour, that leverage A.I.-powered algorithms that act as your personal trainer for adding clubhead speed. TheStack has tracked over 40 million swings from over 60,000 golfers, and on average adds 10 mph of swing speed resulting in over 27 yards of potential distance gains.
In addition to speed training, TheStack has recently expanded into other key areas of performance:
• Stack Putting: Gamified putting practice with strokes-gained analysis and on-course validation.
• Stack Wedging: A science-based short-game platform, powered by TheStack’s Bluetooth-enabled radar, focused on distance control from 140 yards and in.
The partnership with JGAA comes at a critical time in the game’s evolution. Swing speeds at the college level continue to rise, making early development essential for juniors aspiring to play competitively. By training smarter and earlier, junior golfers can gain a lasting edge as they progress through high school, college, and beyond.
Marty Jertson, Co-Founder of TheStack System and JGAA Alumn, emphasized the importance of this initiative:
“Growing up as a Junior golfer in Arizona, the JGAA was pivotal to my growth. I love to see the passionate junior golfers now and want to do my part to help them get easier access to our solutions to help them train their most important golf skills – which is our mission at TheStack. Kids love TheStack because of the structure and gamification of speed training – along with our wedge and putting solutions.”
