4 Minute Workout

Quick 4 is based on the concept of high intensity interval training (HIIT). It follows the popular Tabata protocol, a regimen originally used by Japanese Olympic athletes. It’s similar to the much talked about 7 Minute Workout.

Quick 4 is free for download for two days only.

    This does look good. I do wish I could use it.
