ProsourceFit Plyometric Jump Boxes are a must-have for any home gym, or athletic facility for their versatility and performance enhancement. Plyometric jumping boxes are a simple, yet effective way to improve overall fitness as well as athletic ability. The 3-in-1 design allows you to adjust the height for multiple users or exercises without the need for so many space-wasting platforms. Just turn it on its side to make your workout harder or easier. With three sizes available (30L x 20W x 24H-inch, 24L x 16W x 20 H-inch and 16L x 12W x 14H-inch), you can get up to 30 inches in height, or as low as 12 inches, perfect for any fitness level. These durable plywood boxes are built to withstand heavy use with tight-fitting, interlocking pieces for stability. Boxes with the sizes 30L x 20W x 24H-inch and 24L x 16W x 20H-inch include an internal brace for extra strength and reinforcement. All screws are included and each piece comes with pre-drilled holes for easy assembly. All edges are sanded and rounded for extra safety and two side cut-outs carrying handles make it easy to move boxes around the gym. Boxes are ideal for performing box jumps, burpee box jump overs and stretching. Also, a great addition to any fitness routine to work on lower body strength, explosive power and high intensity interval training. Use for plyometric exercises like step-ups and lateral hops, or general strengthening like squats, push-ups, triceps dips and more. Train like a pro, train with ProsourceFit!
