Bend with both hands or swing with one hand using a strong spring Intensive training With this unisex power arm bar, you can thoroughly train your pectoralis major, biceps, and more. It's an easy-to-use training bar you can do at home. Product size 70cm Weight: 2.3kg I think the bending resistance is around 30kg. One of the rubber grips has deteriorated, but I believe it does not affect usage.
