1. Precision manufacturing processes result in chrome plating that is resistant to rust and peeling, providing a finish with a beautiful shine. 2. The moderately knurled surface (non-slip grip on the barbell) makes it easy to handle and provides a firm grip. This barbell bar, with a total length of 1190mm, is easy to use for upper arm training, such as "arm curls" to train the biceps and "lying extensions" to train the triceps. (A standard 2200mm barbell bar is not suitable for arm training because it is difficult to maintain balance and takes up too much space.)
