Plyo jump boxes are versatile for any type of workout: HIIT, plyometric, or even MMA. Made from high-density EPE foam, our plyometric jump box can hold up to 450lbs of weight. Jump thousands of times to and from this foam box before needing to replace it! Despite the tough structure, our 16lbs jump box is a lot more forgiving than its wood or metal counterparts. With no sharp edges to hurt your shins, you'll feel more confident about attempting your max-height jumps! Foam core and PVC covers prevent slipping all while putting your shins at ease for any missed steps.
