## 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🩷

### ⭐⭐⭐⭐⭐ Perfect, comfortable, with amazing support
*by J***S on May 11, 2025*

This is sincerely the best weight lifting belt I've ever owned. I'm been seriously lifting for most of my life and have had probably 50 different belts, some better than others. I have never had one that was perfect until now. I am 6ft and 250 lbs and the large is perfect, 34 inch waist. I've never had one that support d my lower back so perfectly while still providing COMFORTABLE abdominal support. This thing hugs your hips perfectly with plenty of support but is still flexible for when you are in a deep squat position. I usually only use a belt for squat and deadlift, this one, I didn't want to take off so it goes for the whole workout. I would have gladly paid 100 bucks for something like this but it wasn't a third of that cost. Get one, try it for yourself, make or female, I can't imagine how a belt could be any better, truly outstanding. Thank you RDX for making my workouts safe and comfortable again.
