Physical power is a strange thing. It is only as good as the quality of the tendons than anchor muscles to the bone. Where muscles are the engines that generate strength, tendons are the drive belts that turn it into raw power. And drive belts don't often get paid attention to, until they are truly needed. Vortex is an upper body workout that does just that. It helps your muscles stay toned, for sure, but it also pays attention to the tendons that anchor them and that is why you should do it as often as you can.
Extra Credit: 1 minute rest between sets.
