The multi-directional non-slip surface provides improved grip yet remains soft on the back and hands, making push-ups off the step much more comfortable. Visual guides help improve foot strike and positioning, which aids increased muscle activation. You can even increase resistance by using the step on an incline. The unique circular design and riser “lock in” system, make the step quick and easy to move. Deck dimensions are 42 in x 16 in x 8 in.
