Product Description
Unlock powerful, pain-free leg training with the Fringe Sport Universal Belt Squat System—a commercial-grade rack attachment engineered to build massive lower-body strength while eliminating stress on your spine, shoulders, and elbows. Designed in collaboration with @KAIZENDIYGYM, the Mammoth Belt Squat brings the full functionality of a standalone belt squat machine directly to your existing rack—without the cost, footprint, or complexity.
By transferring the load from your upper body to your hips, this system allows you to squat deeper, train heavier, and push higher volume without back fatigue. Whether you're managing an injury, dealing with limited mobility, or simply want safer, more joint-friendly leg training, the Mammoth Belt Squat delivers unmatched versatility and performance.
With an adjustable length of 39”–48.75”, a 900 lb capacity, and compatibility with every rack size on the market(3x3, 2x3, 2x2 with 1” or 5/8” holes), this is the most universal belt squat attachment ever built. The system includes a padded, adjustable belt with three sets of D-rings for a perfect fit.
Use it for squats, lunges, calf raises, rows, deadlifts, and more—the Mammoth Belt Squat is a true multi-exercise powerhouse.
