Who doesn't love TABATA? Just kidding. If you've done a tabata style workout you probably know how brutal it can be but it's also a really efficient way to get the heart pumping and fatigue specific muscle groups. Try this out as a quick solo workout or to build into a larger circuit. Tag a friend who would do this with you!
