The SKLZ Vertical Jump Boost is an adjustable resistance training system designed to help athletes enhance their vertical leap and explosive leg power. This innovative trainer features resistance cables that connect a comfortable neoprene waistband to adjustable ankle cuffs, engaging key lower-body muscles such as the glutes, quads, and hamstrings. The cables can be repositioned around the belt to target specific muscle groups and are available in varying resistance levels allowing athletes to progressively increase difficulty as their strength improves. Ideal for sports like basketball, volleyball, and football, the SKLZ Vertical Jump Boost is used during plyometric and jump training drills, adding resistance that forces the muscles to work harder. Over time, this resistance-based training builds explosive strength and improves vertical jump height when performing without the added load.
