Every Fitness item is stress tested before it ships — but it's not a certified safety or strength-rated product. Inspect it before each use, and use at your own risk.
Each wedge is engineered and shell/rib-reinforced (not a hollow shell, not a slicer-infill promise) for a real, conservative estimated capacity of up to 150 kg (330 lb) combined bodyweight + barbell load per wedge — 300 kg (660 lb) combined across a normal two-footed pair. Built in PETG for real durability under repeated load.
