HIIT is designed to work the entire body in short, intense blasts, building rest into the workout to improve recovery time and allow the body to more easily access its fuel for the next round. It’s tremendously effective because it keeps the body guessing.

HIIT is an awesome way to quickly and efficiently detox your blood (and provide it with a brand new batch of oxygen), in addition to your muscle cells, which will be able to regenerate and rebuild more effectively with a regular HIIT routine.
