Overview
The ProFitness Weight Lifting Belt is a 5mm leather belt for squats, deadlifts, and other heavy compound lifts, made for lifters who want added core bracing under load.
Leather weight belts like this work by giving the torso something rigid to push against during a brace, which is what the core-stability claims in the listing are actually describing. At 5mm it sits on the lighter end of leather lifting belts, thinner than the 7 to 10mm belts competitive powerlifters typically use for maximal singles.
- 5mm thick leather build
- Adjustable buckle closure
- Designed for squats, deadlifts, and overhead lifts
- Unisex sizing
Who it's for
Suited to lifters doing squats, deadlifts, or overhead presses who want belt support without the stiffness of a thicker competition belt. Serious powerlifters chasing max singles may prefer a thicker, stiffer belt.
Strengths and trade-offs
Drawn from this product's published specifications.
- 5mm leather construction for repeated gym use
- Adjustable sizing for men and women
- Lighter and more flexible than thick competition belts
- Thinner than the 10mm belts used in powerlifting competition
- No reviews available to confirm long-term durability
Performance notes
A 5mm leather belt has enough rigidity to brace against during a lift while remaining more flexible than thicker belts, which some lifters prefer for comfort during warm-up sets and accessory work. The tradeoff is less rigidity than a thicker belt offers on true maximal attempts.
