How do you get high-intensity high jumps with low risk and low impact? The ZIVA Performance Plyo Box. Our plyo box consists of a commercial-grade, high-durability anti-slip PVC skin that easily goes on and off of a PE foam core that athletes can set any of 3 ways for different intensities. Turn it one way, and it's a tough 20" step platform that works the calves, hamstrings, and glutes. Turn it another, and it's a high-intensity jump workout tool that challenges you to leap 24" high and land gracefully on its soft surface. Give it one more turn, and you have to soar to 30" for workouts that build speed, explosivity, and power. Our 3-in-1 Plyometric Jump Box is an uncomplicated yet endlessly useful tool that requires no special set up, no assembly, no installation, and no tools. Just put it where you want, and workout how you want.
