REP® Belt Squat

Name: REP® Belt Squat
Brand: REP Fitness
Rating: 2.27 (5 reviews)

REP’s Belt Squat is a rack attachment, not a standalone machine – it bolts onto the lower cross-members of a PR-4000 or PR-5000 V2 power rack (not the Apollo rack) and routes a cable through the rack’s Lat Pulldown/Low Row or Ares attachment to create a 1:1-ratio, plate-loaded belt squat station. Built from 11-gauge steel with a matte black powder coat, aluminum pulleys, and a plastic-coated wire-rope cable, it’s rated to 600lb, weighs 41lb, and measures 25.3”D x 41.3”W x 8.1”H. It locks into the rack with quick-release pins and takes about 3 minutes to install.

Beyond belt squats, reviewers use the same cable and pulley system for weighted pull-ups and dips, calf raises, marches, split squats, and rack pulls – REP added the pull-up/dip use case explicitly. The tradeoff for the compact, rack-integrated design is that reps start loaded from the floor rather than the top, and the front pulley post can lift off the ground under heavy load, both of which limit how deep and how heavy a dedicated belt squat can go compared to a standalone unit like the Rogue Rhino. It requires already owning a compatible rack and lat attachment, so it can’t be bought or used on its own.

What is a Rack Attachment?

What rack attachments are

Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.

Compatibility comes first

An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.

REP’s Belt Squat turns an existing PR-4000/PR-5000 rack and lat-pulldown attachment into a plate-loaded cable station, and reviewers rate it highest for versatility – swapping between belt squats, weighted pull-ups and dips, calf raises, marches, and rack pulls off the same $279-$310 add-on. Functionality is the standout weakness: it starts loaded from the floor rather than the top of the rep, so most owners end up rigging a DIY chain-and-strap workaround, and the front pulley post lifts off the ground under load, capping squat depth. Independent verdicts split hard on whether that tradeoff is worth it – Garage-Gyms.com scored it 8.9/10 and praised its build quality and value, while a longer-term Twisted Barbell review says it collects dust between uses and isn’t worth the ~4-minute install/uninstall each session – a split echoed by REP’s own on-site rating of just 2.27/5 across 5 reviews.

+Versatility: doubles as a floor-mounted cable station for weighted pull-ups, dips, calf raises, marches, and rack pulls, not just belt squats (YouTube: Garage Gym Reviews; Gray Matter Lifting)
+Value: one of the cheapest belt squat attachments on the market at $279-$310, versus a standalone machine like the Rogue Rhino (Garage Gym Reviews; Garage-Gyms.com)
+Build quality: 11-gauge steel construction with aluminum pulleys and stainless steel badges holds up to smooth, consistent cable tension (Garage Gym Reviews; Garage-Gyms.com)
+Functionality: 1:1 resistance ratio and quick-release pin mounting let it drop onto any cross-member position in the rack in about 3 minutes (Garage-Gyms.com)

−Functionality: no top-of-rep starting position -- every rep is effectively an Anderson squat from the bottom unless you rig a DIY chain-and-strap workaround (YouTube: Garage Gym Reviews)
−Functionality: the front pulley post lifts off the ground under load, pulling the lifter forward and limiting achievable squat depth (YouTube: Garage Gym Reviews; YouTube: Twisted Barbell)
−Build quality: no carry handles on a roughly 50lb attachment with sharp edges makes installing/uninstalling it each session cumbersome (YouTube: Twisted Barbell)
−Value: requires already owning a compatible PR-4000/PR-5000 rack plus the Lat Pulldown/Low Row or Ares attachment -- it can't be used standalone (repfitness.com; Garage-Gyms.com)
−Durability: the cable can snag and fray against the pulley if not watched carefully during setup (YouTube: Garage Gym Reviews)
