## Description

desertcart.com : 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 : Sports & Outdoors

Review: Secure and Supportive. - 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.
Review: Great Quality - Have used it only once. Support is great, and it fits perfect. Will recommend if you love weight lifting, as it helps prevents injury. Quality is great, and love the color🩷
