@thestacksystem BRAVO!
Entrenar más putts NO significa meter más putts.
Entrenar mejor, sí.
Hoy tocó sesión con thestacksystem Putt Training: trabajo con propósito, decisiones reales y datos que importan.
✅ Distancias variadas
✅ Pendientes diferentes (uphill, downhill y caídas laterales)
✅ Feedback objetivo
✅ Enfoque en Strokes Gained Putting
✅ Transferencia directa al campo
Muchos jugadores entrenan repitiendo el mismo putt una y otra vez.
Pero el golf no funciona así.
En el campo nunca tienes dos putts iguales.
Por eso el entrenamiento debe desafiar lectura, velocidad, ejecución y adaptación constante.
El objetivo no es embocar más en el entrenamiento.
El objetivo es que tus errores sean mejores y que tus decisiones sumen golpes ganados cuando cuenta.
📉 Menos putts regalados
📈 Más consistencia
📈 Más Strokes Gained
¿Tú entrenas para sentirte bien… o para jugar mejor? 👇

What makes Stack Radar different from a standalone speed radar?
It’s not just the hardware — it’s what the Bluetooth connection unlocks inside TheStack App.
Yes, Stack Radar measures Swing Speed and Ball Speed, estimates Carry Distance and Smash Factor, and even has a speed threshold feature.
But the real advantage is the seamless connection to TheStack App.
❗️That connection unlocks advanced features like:
• Temperature + altitude adjustments
• Fine-tuned ball speed and launch settings
• Accurate carry feedback
• Hands-free speed and wedge training
‼️Most importantly, Stack Radar unlocks app features exclusive to Stack Radar users:
• Stack Wedge — personalized, gamified wedge practice from 140 yards and in
• Practice Tracker — structured full-swing practice with data-driven insights
• Seasonal Circuit — global wedge competitions with leaderboards and prizes
Stack Radar isn’t just a radar giving you numbers.
It’s a connected, data-driven training ecosystem designed to help you practice smarter and improve faster.
Seeing the value yet?? 😎

Should Junior Golfers be speed training?
Golf’s #1 Instructor, Mark Blackburn, sits down with TheStack co-founder Sasho MacKenzie to talk golf science at The PGA Show. An audience member asked about speed training for juniors — here is a quick snippet of Mark’s answer.
