Description
RDX 6 Inch Leather Weightlifting Belt Black – Extra Wide Lumbar Support Gym Belt
The RDX 6 Inch Leather Belt in Black is an extra-wide lifting belt built to give maximum support across your lower back and abdomen during heavy training. This listing is for size Small.

- Extra-wide 6 inch panel: broad coverage for more support around the lower back and core
- Contoured shape: moulds to your body for a comfortable fit under load

- Reinforced construction: stitching, rivets and a sturdy buckle for repeated heavy use
- Black finish: a classic, understated look for the gym
- Approved standards: meets IPL, USPA and GPC standards according to the seller
- Size Small: suits smaller waists – check the RDX size chart before ordering
What Is It?
The RDX 6 inch leather gym belt is designed for lifters who want a wider panel of support than a standard 4 inch belt. A belt like this gives you something firm to brace your abdomen against, helping you feel more stable on squats, deadlifts and overhead presses. The wide back panel spreads pressure across the lumbar region, and the leather is built to soften and shape to your body over time. Reinforced stitching and rivets help it withstand regular heavy use, and the black finish keeps it looking smart session after session.
Who Is It For?
This belt suits bodybuilders, powerlifters and serious gym-goers who prefer a wide, supportive belt for their heaviest working sets. Note that a 6 inch belt is a taller belt, so it works best if you have enough distance between your ribs and hips. Smaller-framed lifters may find a 4 inch belt more comfortable, so consider your torso length before choosing. Measure your waist where the belt will sit and compare it with the RDX size chart. Size Small is intended for smaller waist measurements. A belt does not replace good technique or sensible progression, so keep working on your bracing and form as you add weight.
