Mammoth Belt Squat

The Mammoth Belt Squat is Fringe Sport’s rack-mounted, lever-style belt squat attachment: it loads weight around the hips instead of across the shoulders, so lifters can add deep-range squat volume without back or shoulder strain – useful for anyone working around a back, knee, or elbow issue, or just wanting extra leg volume that doesn’t beat up the spine. A two-piece, bolt-together design lets the lever arm extend from 39” to 48.75”, and it mounts to 2”x2”, 2”x3”, or 3”x3” rack uprights with both 5/8” and 1” holes – the upright can even be spun to switch rack sizes – which is the feature reviewers single out as its main edge over simpler single-length lever attachments like the Revolt.

Independent reviewers (Garage Gym Reviews, The Jungle Gym Reviews, and three YouTube channels) are consistently positive: 11-gauge steel with UHMW rack protection reads as “overbuilt” for the price, and the padded three-D-ring belt is included rather than sold separately. The same critique recurs everywhere it’s covered, including GymRadar and r/homegym: like any lever-style belt squat, the arc of the lever introduces some forward pull at heavier loads (unlike a cable-driven machine such as the Rogue Rhino), and the optional kickstand – widely treated as a near-mandatory add-on for getting into position under load – varies in fit/wobble between units. Both are tradeoffs of the lever design and accessory ecosystem, not build defects in the base unit itself.
