Hi Mark,

Unfortunately there’s no way to “pause” Grit Score while injured. Grit Score is intentionally designed as a pure measure of program adherence, regardless of the reason for missed sessions.

We know life happens — injuries, travel, work, etc. — but keeping the metric objective is what makes it meaningful over time.

Hope you’re back Stacking soon 👊

Welcome to the 10K Club, Jay!

The 10K Club recognizes Stackers who have accumulated 10,000+ Stack swings - a milestone that reflects commitment and consistency over time.

To celebrate the achievement, members receive a set of gold Stack weights as a tribute to the work they've put in along the way.

Congratulations, Jay.

@thefifthtim Sorry to hear, Tim. Can you reach out to us via the “contact us” in your app please. We can troubleshoot.

Small enough to fit in your pocket. Smart enough to change the way you practice.

The Stack Radar gives you instant club speed feedback on every swing. Use it during speed training sessions, on the range, or even when you're hitting balls on the course.

When you can measure speed instantly, every swing becomes more intentional.

Pair it with TheStack App in Wedge Mode and it gets even smarter.

The app calls out target distances and scores your shots in real time, turning wedge practice into a data-driven, gamified training session designed to sharpen distance control from inside 150 yards.

🔥Train speed.
🎯Dial in your wedges.
🧠Practice smarter with The Stack Radar.

@TheStackSystem Just completed my 10th Stack program and am holding steady at my highs since beginning. Will be 60 next month. Fun hitting it past my buddies and using Wedges into greens. Started Stack Wedge and Putting programs. Highly recommend Stack system. Now Look out!

Looks like my @TheStackSystem wedge work is paying off. Haven’t missed a green from inside 100 yards this year (8/8)

Also fairways are overrated. Keeping my drives in play is more important, and 82% for me is pretty good. Need to hit approach shots closer than 45’ though…
