💯Michael is right. We take the guesswork out of speed training — fully guided, custom programs that adapt as you do. And it’s not just players who see the value — MyGolfSpy has ranked The Stack the “Best Training Aid” for five consecutive years.🤯
@jkeller0616 It’s honestly not that complicated as the stack system app gives you all the instructions. If you do some strength training exercises to go along with it then even better. Just try to swing faster

This is wild. Christo Lamprecht carries 2 drivers and 5 wedges. Half his bag is either a driver or a wedge?!

Lots of options at the top end of the bag. Latest pod goes on a deep dive
Need a new option for the top-end of your bag? Hear why an #iDi driving iron could be an option for a wide-range of players and gain a better understanding of how you should build out your bag between your driver and longest iron: https://t.co/rHq42GUfC2

Bat speed training system used to biohack your bat speed. The Stack System unlocks precision speed training from leading biomechanist, Dr. Sasho MacKenzie.
"I love every bit of it." @CliffFloyd30 is all in on the analytic focus of improving bat speed after seeing what hitting coach David Popkins has done with the Blue Jays.

Lesser known but sneaky good way to read greens is think about the time of putt

Well deserved 👏🏼 Congratulations on the W - and your higher speed - and higher World Ranking!
Thanks to the @TheStackSystem for sending me these gold weights for winning the French open haha. It’s one of the few tools in golf that can help almost every golfer imo.

I hate all the mistakes from rookies labeled as “no experience.” It’s still golf and all these guys have played under massive pressure. I find it lazy analysis

When I was a kid, the best golf tools felt out of reach. Now, with TheStack Accelerator, we’re changing that — helping juniors access @TheStackSystem Speed, Wedging, and Putting to gamify their training like the pros. Parents and kiddos:

After a full week in office + Saturday junior fitting, @JimmyHardK headed to Cali + made four birdies in last five holes to Monday Q for @ProcoreChamp ... Then closed with two gutsy pars Friday to post 2-under for 36 holes, which Is virtually certain to make cut as things stand!
Is there a better Monday Qualifier in the game than @JimmyHardK ?!? Dude just did 40+ hours last week in the office and worked a ProdiG Junior Fitting event all day Saturday. Have a week, pro. @PingTour @MinesAthletics @TheStackSystem @MinesGolf
