What are Fitness Mad Push Up Bars? The Fitness Mad Push Up Bars will enhance your push ups from the ground up by allowing variable ranges of motion. Designed to ease the strain on the wrists during a push up, the bars allow for a greater chest workout as the drop in elevation is greater than from a standard push up. How do they work? The polyproplene bars weight a mere 600g making them lightweight yet incredibly sturdy. Simply snap them together & train!
