VertiMax is one of the most visible training devices today. The VertiMax is a small platform, with cords similar to bungees attached to it for jumping and other sporting actions. As its name suggests, most of the attention the device gets is for improving jumping performance, especially an athlete’s vertical jump. The Vertimax resistance allows athletes to achieve the highest resisted training velocities possible during training drills. And the faster you can train with a load, the greater your high-speed strength gains or power outputs will be.
