Overview

Cinching a cowhide and suede leather band around the waist, the RDX WBS adds a padded lumbar section and a dual pronged roller buckle. It is a four inch Black version made for powerlifting and general weight training.

Thick leather with a padded back gives rigid abdominal bracing for maximal pulls and presses, which is the reason to buy a belt like this. The limitation is that the size information is confusing, so a wrong size is the main risk.

Who it's for

A gym lifter training squats, deadlifts and overhead work who prefers a stiff leather support with a tongue-style buckle. Anyone between sizes, or lifting only light weights, can skip it until the size chart is clear.

Pros and cons

Pros
  • Stiff leather aids bracing
  • Roller buckle eases adjustment
  • Padded lumbar section
  • Suede interior listed
Cons
  • Waist size fields conflict in the listing
  • Leather needs a break-in period
  • Weight not listed

Performance notes

A thick leather belt works by giving the abdomen something firm to push against, which raises pressure in the trunk during a heavy lift. Two prongs share the pull on the strap, and the roller lets it slide through, which helps with tightening between sets. The hole spacing sets how finely the fit can be tuned.
