Health-club Size: Measuring L110cm/43 inches x W42cm/16.5 inches for the platform, this gym-sized aerobic step is safer and more functional than a circuit type. With this health-club size, you can use it for all your step aerobics routines or as a bench for abdominal or balance exercises. Slip-resistant Surface: The anti-skid grooved EVA platform surface increases the friction during your exercises that provide good grip for sweaty hands or slightly wet shoes, ensuring you a safe and secured workout experience. 3 Levels for Various Needs: This fitness step features 4 risers (2 on each side) which you can use to easily adjust the stepper height from 11cm/4 to 16cm/6 to 21cm/8, fulfilling your different training goals. Non-marking Feet: The bottom of the platform and risers are padded with non-skid and non-marking rubber feet. You can use this aerobic step platform on almost any type of solid surface including hardwood, laminated flooring, tile, gravel and carpet. Gear U
