Our Take

Serious swing training for golfers ready to dial in speed with real data.

TheStack turns swing training into a measurable, coach-guided process—no guesswork, just weighted overload work and an app that tracks every rep.

At $299, it's a premium investment, but you're paying for a full-year app membership, 60+ instructional videos, and a training system backed by a 55,000-user dataset—not just a weighted club.

Who it is forGolfers committed to measurable improvement who want coaching and data alongside the training aid itself; best suited for those with iOS or Android and the discipline to follow structured sessions.

How We Judged It

What to check before you buy

Adjustable Overload Training

30 weight options

You get precision tuning rather than a one-size-fits-all stick. The 30 adjustable weight combinations let you dial in overload (heavier) or overspeed (lighter) work based on your swing phase and goals. This specificity is what separates systematic training from casual practice.

App & Coaching

1-year membership included; 60+ expert videos; performance tracking; putting trainer (iOS only)

The hardware is half the story. TheStack App coaches you through timed sessions, logs personal bests, and compares your data to other users. You also get 60+ videos on swing mechanics and speed drills curated by a biomechanics expert. Stack Putting adds short-game work with guided sessions and tendency analysis.

Proof & Endorsement

Used by Matt Fitzpatrick (2022 US Open winner); endorsed by Golf Digest instructors Mark Blackburn and Chris Como

TheStack isn't a celebrity gadget—it's a tool trusted by tour pros and the coaches who shape them. The endorsement carries weight because it comes from people paid to find what actually works.
