Customers say
Customers find the weightlifting belt to be of solid construction, comfortable, and good value for money. They appreciate its support, with one customer noting it handles 365lb squats and deadlifts well, and its functionality, with one mentioning it works great with chains for weighted dips. The fit and hold receive mixed feedback – while some say it fits well and stays in place during workouts, others report poor sizing and thin velcro that doesn’t stay together.

Solid Back brace
Very comfortable and durable to use. Great support and easy adjustment and perfect size for me.

Perfect, comfortable, with amazing support
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.

Solid Support with Comfortable Fit
I’ve been using the RDX weight lifting belt for a few weeks now, mainly for squats and deadlifts, and overall I’m really impressed. The 6.5” padded back support offers great stability, and the auto-lock mechanism feels very secure. It’s easy to adjust and stays in place throughout my workouts without digging in or feeling restrictive.The materials seem durable and well-made—definitely suitable for moderate to heavy lifting sessions. I like the sleek gray color too, it looks clean and professional.The only reason I’m giving it 4 stars instead of 5 is that the Velcro could be a bit stronger for really intense lifts—it holds fine for now, but I wonder how it’ll wear over time. Still, a great value for the price and a reliable belt for both beginners and intermediate lifters.

Secure and Supportive.
Strapped this on for my deadlifts and squats during a 5×5 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.

Comfortable but I couldn’t get it tight enough
I really wanted to like this weight belt and it was very comfortable and did give good support but with the clasp I just could not make it as tight as I wanted for doing squats. Ended up taking it back with absolutely no hassles and love the RDX brand. I ended up getting one of their leather weight belts and absolutely love it. Overall this brand is a good quality brand at a very reasonable price compared to what you would get other stuff for of a comparable quality. At least in my opinion.
