What is the maximum belt thickness allowed?

• A. 8 mm
• B. 12 mm
• C. 15 mm
• D. 20 mm

Answer: (B)

The rule tests how thick a lifting belt may be to keep equipment standards consistent and fair. A belt up to 12 mm thick provides useful bracing without becoming an oversized aid, so lifters can still brace their core without the belt giving excessive support. Belts thicker than that—like 15 mm or 20 mm—would offer far more abdominal support and could create an uneven advantage, which is why they’re not allowed. A belt as thin as 8 mm would be permissible, but it doesn’t reach the maximum allowance. Therefore, the maximum allowed thickness is 12 mm.
