What Is It?
A weightlifting belt gives you something to brace against when you take a big breath and tighten your core, helping you feel more stable under load. RDX’s 4 inch leather belt is a popular choice because it is comfortable enough for regular gym use yet sturdy enough for heavy training. The moderate width leaves plenty of room to move, so you can squat deep or pull from the floor without the belt digging into your ribs or hips. Black leather with gold accents gives it a distinctive look on the gym floor. With ten holes for adjustment, it is easy to dial in a fit that feels secure without restricting your breathing.
Who Is It For?
This belt suits gym-goers, bodybuilders, powerlifters and CrossFit-style athletes who want extra support on heavy compound lifts. It is a good step up for anyone moving from lighter training to heavier working sets. A belt should not be a substitute for good technique or gradual progression, and it is best worn for your heaviest sets only. To choose the right size, measure around your waist where the belt will sit and compare it with the RDX size chart. This listing is for size Medium, so measure carefully before you order.

Directions
Wear the belt around your waist, over the navel, with the wider back panel sitting across your lower back. Fasten it snugly enough to brace against, but not so tightly that you cannot breathe or move. Take a deep breath into your stomach and brace your core before each heavy rep. Choose your size by measuring your waist and checking the RDX size chart.
Warnings
- Use the belt for heavy working sets only and rely on good technique. It is not a replacement for proper form or progressive training.
- Do not use a damaged belt. Check the stitching, rivets and buckle before each session.
- Stop exercising and seek medical advice if you feel pain or dizziness.
Storage
Wipe clean with a damp cloth and allow to air dry naturally. Avoid machine washing, soaking or direct heat. Store flat or hung in a dry place.
