The Evolution Athletic Olympic hammer curl bar, (or tricep curl bar) with brass bushes is designed to work the muscles from different angles and to reduce the stress that a straight barbell can place on the joints in the arm (the wrists, elbows and forearms) by allowing for a much more ergonomic grip of the bar.
Compatible with any Olympic plates, it features a solid nickel plated finish with two brass bushes in each end and circlip ends, giving you a smoother spin with no annoying bolts to fall out.
