The RDX Weight Lifting Belt is a 4-inch cowhide leather belt with a padded lumbar back, a twin-prong roller buckle and 10 adjustment holes, priced at £25.99. It takes the top spot in this guide on the strength of 11,746 ratings averaging 4.5 out of 5, and a Best Sellers Rank of 1st in Weight Lifting Belts.

The number worth reading twice on this listing is the waist size. The specification table gives "Waist Size: 37 Inches", which on its own reads like a fixed measurement. The same table's Size field says "2XL Fits 37 to 43 Inches", and the sizing bullet spells out the whole chart: S 19"-23", M 23"-28", L 28"-32", XL 32"-37", 2XL 37"-43", 3XL 43"-48". So 37 inches is the bottom of the 2XL band, not the size of the belt you receive — RDX's own bullet opens with "DO NOT TRUST YOUR PANT SIZE". The thickness figures, by contrast, do line up: the specs list Item Thickness as 7 Millimetres and the bullet text calls it a "7 mm thick" belt. Everything on this page is taken from the Amazon listing; we have not tested the belt ourselves.

## Questions people ask

**What sizes does the RDX belt come in?**

The sizing bullet gives six: S (19"-23"), M (23"-28"), L (28"-32"), XL (32"-37"), 2XL (37"-43") and 3XL (43"-48"). RDX tells buyers not to trust their pant size and to measure against that chart and its measuring instructions.

**Which version of the belt is this?**

The title advertises both a 4-inch and a 6-inch padded lumbar back. The Colour field on this listing reads "Black 4 Inch", so this is the 4-inch belt.

**How thick is the RDX belt?**

The specification table gives Item Thickness as 7 Millimetres, which matches the bullet text describing a "7 mm thick" weightlifting belt.

**How many adjustment holes does it have?**

Ten. Both the title and the buckle bullet refer to 10 precision-drilled holes for the dual-pronged roller buckle.

**What is the RDX belt made of?**

Genuine cowhide leather, according to the durability bullet, with a suede leather inner for comfort. The Material field simply says "Leather".

**How heavy is the RDX belt?**

The specification table lists Item Weight as 408 g. The listing text does not quote a weight, so there is no second figure to compare it against.
