It gives great lower back support when lifting heavy weights and feels secure without being uncomfortable. The quality is really good, easy to adjust, and perfect for squats, deadlifts, and other heavy lifts. Definitely a great gym purchase! ### ⭐⭐⭐⭐⭐ Great belt for the price *by C***R on May 17, 2026* Sizing seems weird .. according to the chart I wear a xl … it feels very secure and supportive without digging in to my torso and thats even with it pulled tight . The quality feels top notch compared to my harbinger belt I have had for years . So far very happy with this belt . Great price and provides core support when lifting heavy . Just in case you want to know this is not to support your lower back but to stabilize it in heavy lifts . Still use proper form . ### ⭐⭐⭐⭐⭐ Secure and Supportive. *by J***R on November 3, 2025* Strapped this on for my deadlifts and squats during a 5x5 program, hitting 315 lbs for reps without the usual lower back twinge—first time in years. The 6.5” contoured padding hugs the lumbar curve perfectly, blending EVA foam and SpongEX for cushioned stability that doesn't ride up or pinch, even after sweaty sets. Auto-lock buckle snaps in under 5 seconds with a satisfying click; tension holds firm through max efforts, no fumbling mid-rep like with Velcro-only belts. Pros: Unisex sizing fits my 32" waist snug (easy hole swaps via screwdriver once); nylon-poly build shrugs off gym grime and holds up to daily abuse; under $40 steals value from pricier leather options. Quick-release strap for fast on/off between exercises. Cons: Initial adjustment takes a couple minutes; the fabric velcro can snag hair if you're not careful, and it's not IPF-legal for comps. Verdict: If you're powering through compounds without a chiropractor on speed dial, this belt delivers pro-level brace on a budget. Boosted my confidence (and PRs)—essential for garage warriors or gym grinders. ## Frequently Bought Together - RDX Weight Lifting Belt AUTO LOCK, 6.5” Padded Back Support, Men Women Gym Fitness Strength Training, Bodybuilding Powerlifting Weightlifting Workout, Deadlift Squat, Pro Exercise Equipment - Knee Compression Sleeve for Men and Women (2 Pack), Knee Support Brace for Running and Work out (Medium) - ATERCEL Workout Gloves for Men and Women, Exercise Gloves for Weight Lifting, Cycling, Gym, Training, Breathable and Snug fit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/309617481-rdx-weight-lifting-belt-auto-lock-6-5-padded-back](https://www.desertcart.be/products/309617481-rdx-weight-lifting-belt-auto-lock-6-5-padded-back) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-23*
