Keep this 4 minute circuit mega-INTENSE; otherwise, you are not going to benefit from Tabata. If you are in a rush, this is an ideal 4-minute workout to cram into your hectic morning schedule. Maximize fat-burning by doing this 4-minute workout fasted as soon as you wake up … and stay fasted for at least 2 hours after the workout (you can drink your BCAAs). Set your timers for 20 seconds of work and 10 seconds of rest.
