Love this bar!
"One of my favorite pieces of equipment. Part of the description on the website says it can alleviate pain in the elbows with the curved bar and using an open grip around the balls but for me, I have such bad arthritis in my wrist that normal size barbells and cable attachments is difficult and sometimes impossible for me to grip tightly. My wrist can give out and drop the bar or cause increased pain during use. Cupping the balls on this attachment with an open palm, I can perform the movements with ease and I am not concerned with causing further injury. Spacing between the balls is perfect for what it is designed for. Definitely recommend as once you get used to it, you will definitely love it."
