KEEP AIR POWER: The faster, lighter spring matched with an air-filled punch ball makes FLEX AIR a unique impact rod. The air ball on top is lighter, and the spring longer, making it much faster.

360 Degree Striking Gut: The Flex Air Reaction Ball tests your movement, speed, accuracy, and timing due to its unpredictable nature in swiveling back after each strike.

Adjustable Height & Upgraded Amplifier: Easily adjust Flex Air’s height using the hand valve. Simply choose your height, lock the valve, and start punching.

STURDY BASE: The base should be filled with water or sand for best stability. It includes 12 suction cups to prevent scratches and enhance the bag’s attachment to the floor.

WHAT CONTAINS: All parts needed for the Flex Air bar, an air pump, and extra speedball.

SHOCK ABSORBENT: The steel spring absorbs 100% of the shock, ensuring immediate rebound for faster performance.
