TheStack Accelerator Program
TheStack Accelerator makes it easier than ever for juniors to access personalized, gamified training across three core scoring skills: Swing Speed, Putting Performance, and Wedge Precision.
The program integrates The Stack’s cutting-edge speed training hardware, gamified putting practice, and precision wedge mode — all powered by real-time data, custom programming, and performance tracking in The Stack App.
At what age can my kid start speed training with TheStack?
Many kids as young as 7 years old enjoy and benefit from training with The Stack System. However, age alone shouldn’t determine whether your child should start speed training. It’s important to consider the following factors:
Enjoyment - Does your child enjoy training for golf? While The Stack System is designed to make speed training engaging and fun, it’s still structured training. If your child doesn’t find it enjoyable, their time may be better spent on other activities they love. For younger kids, we discourage replacing free play or participation in other organized sports with Stack training. That said, The Stack System requires only about 45 minutes per week and can easily be incorporated before or after golf practice, making it a manageable addition to their routine.
Training Volume - How many golf swings is your child taking each week? If they only practice a couple of hours per week, adding 45 minutes of Stack training can be beneficial. However, if they’re already practicing for several hours daily and take hundreds of swings each week, adding more training could increase their overall workload to an unhealthy level. In some cases, replacing some range time with Stack sessions can be advantageous. Proper training volume is critical in youth sports to minimize the risk of injury. The Stack System is a low-volume program with loads tailored to each athlete, but it’s important to monitor your child’s total workload, including swings, to avoid overtraining.
Developmental Readiness - The Long-Term Athlete Development (LTAD) model, used by many youth sports organizations, identifies critical windows of opportunity for speed development. For girls, these windows typically occur between the ages of 6–8 and 11–13 years. For boys, the first window generally occurs between 7–9 years. During these periods, children may respond particularly well to speed-focused training. However, it’s essential to tailor training to their individual development and readiness.
In summary, kids as young as 7 can benefit from The Stack System, but it’s important to assess their interest, current training volume, and developmental stage to ensure a positive and productive experience.
