Hyperwear SteelBell Steel Shot-Filled Ultra-Durable Neoprene Free Weight Slam Ball

A heavy duty neoprene bag filled with steel shot, the Hyperwear SteelBell is one of the most functional, intense and unconventional free weights ever created. Extremely durable, it can be used like a medicine ball, slam ball, dumbbell or kettle bell for exercises like presses, squats, slams, swings and lunges. Tiny balls of steel shot make the SteelBell incredibly lively and challenging. The true SteelBell advantage is for exercises to build explosive power and full body stability. SteelBells can also be thrown, caught and slammed allowing a vast variety of exercises individually or with a partner. US Patent 8,622,877 B2. SteelBell is a registered trademark.
