Attractive space saving functional training set. Includes sleek storage rack 6, 9, 12, 15, and 20kg Slam Balls.   

• This premium slam ball is the ideal functional training and conditioning tool for gyms, sports facilities, boot camps, CrossFit boxes, and PT studios.
• Crafted from heavy-duty rubber, this ball is designed to endure extreme impact.
• The rough-textured surface allows superior grip even when wet.
• The ball is filled with iron ore sand to provide for fluid motion and instability. 
• Often referred to as ‘dead balls’, slam balls wont bounce or roll away, and are softer on fingers and hands.
• Each ball is also equipped with an air valve, which can be used to adjust air pressure and firmness, as well as to soften impacts.

Please note use and care:

• Always warm up heavy balls before use. Over time, cold sand in the Slam Balls can settle and become hard. Slamming a compacted/cold ball can cause valve damage.
• Rolling them on the ground until the sand feels fluid and the ball feels warm is the best way to do this.
• Heavy weight balls also require frequent inflation to avoid pressure on the valve and maintain a round soft shape and feel.
