Rank #1 in Best Weightlifting Belt 2026: 10 Ranked, Specs vs Marketing
RDX Cowhide Leather Weight Lifting Belt, 4 or 6 Inch Back
Price and rating as shown on Amazon when we collected them. Both change.
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.
