Round Ball Training Grips are easy to use weight training aids that let you train more effectively. Designed to add variety, increase grip strength, reduce joint discomfort, and improve sports performance. These grips allow a unique style of grip that can improve overall grip strength by letting the user’s hand naturally form around the handle. This can also help reduce strain on the wrists and shoulders and help strengthen your grip. Simply slip the training grips onto your bar, dumbbells, kettlebells or cable handles.
