Why Do So Many Lifters Train in a Lifting Belt?
Hint: once you wear one, there's no going back.
Heavy day. You set up for your heavy sets, take a big breath, and start the rep. Then, right as the bar slows down, your midsection softens, leaving your hips shooting back and your lower spine rounding under the sheer, brutal weight of an agonizing grind.
It isn’t a lack of leg strength; it’s a lack of midsection stability. There's a reason so many lifters buckle up before going heavy. Here are eight of them.

They Give Your Brace Something to Push Against
Bracing is pushing your abs out hard against something. Without a belt, there's nothing there. With one, your midsection drives into a rigid wall of leather, so you can build more pressure around your trunk and stay tight through the whole rep.

Top Sets Feel Solid Instead of Shaky
It's the moment the bar slows down that shows the difference. Lifters tell us their midsection stays locked in through the sticking point on heavy squats and deadlifts, instead of softening right when they need it most.

10mm Is the Sweet Spot
Not a flimsy belt that folds when you brace. Not a 13mm board that takes months to break in. 10mm leather is rigid enough for max-effort sets and comfortable enough to wear for squat, bench and deadlift.

A Hole Tighter for Squats. A Hole Looser for Deadlifts.
Most lifters want a different tightness for squats and deadlifts. The double roller prong lets you change it right at the bar, between sets, by hand.
No screwdriver, no re-mounting a lever.

You Don't Need a 600 lb Deadlift
Powerlifters and strongmen made belts standard. But you don't need elite numbers to benefit. If you squat and deadlift heavy every week and your technique is dialed in, a belt helps you get more out of every top set.
The 10mm Double Prong is IPF-approved, so it's meet-ready if you ever compete.

Love It or Your Money Back
