Introducing the Infinity Series by Bolt Fitness Supply– a premium collection of cable pulley attachments designed for infinite performance. Crafted from solid steel and featuring a medium grad knurling, the Infinity Series provides an ideal balance of grip and durability. The addition of an extra pivot point offers enhanced flexibility and a wider range of motion for the user. A chinning-bar cable attachment is one of three must-have attachments for gym owners with cable machines and functional trainers, the other two being the cable handle and the lat pull-down bar. Chinning bars are primarily used to train the muscles of the back, shoulders, and arms through a variety of pulling motions. Attach your chinning bar attachment to a cable that offers vertical resistance for a neutral grip (palms facing each other) pull-downs. Attach it to a cable that offers horizontal resistance to perform rows, two compound exercises that engage all the muscles in the back, but especially the latissimus dorsi and the biceps.
