4 Piece Plyobox Set (12",18",24",30") by Powermax
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. The top platform is covered with 10mm thick rubber track 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.
