Tabata is a very high intensity interval training program. Basically, you perform 20 seconds of all out work, followed by 10 seconds of rest. That is then repeated for a total of 8 sets. So the total workout is only 4 minutes, including rest periods!

Ive used this protocol with many exercises and Im planning to start working it in with my clients.

Has anyone out there used this program for any extended periods? If so, what did you get out of it? What exercises did you use? How many times a week did you do the workout?
