Jumping on and off boxes is one of the best plyometric exercises to improve leg power, speed, and strength. Each box is constructed of 1" square steel tubing. Top platform is steel reinforced 1/4" aluminum covered with a rubber surface. Anti-skid rubber is located at base corners to prevent slipping and to protect floors. Tapered design allows for much greater stability, and easy stacking for storage.
These soft plyoboxes are designed to be less intimidating than steel boxes for the developing athlete. Standard 28"x28" blocks. The 3" block is built with 2.2# density polyethylene foam, other sizes with 1.8# which provides stability, shock attenuation, and performance. Boxes are secured for stacking with industrial strength hook and loop fasteners and have a durable vinyl cover. All boxes are less than 28 lbs. and have two reinforced handles for portability. Available in 5 sizes or a set of 5 (1 of each size).
