What do you do exactly?
basically, it is 8 rounds
each round is 20 seconds of sprinting AS HARD AS YOU CAN followed by 10 seconds of walking
the workout is 4 minutes long BUT IT IS THE GREATEST/MOST EFFICIENT WAY TO BURN FAT/GET INSANLEY SHREDDED EVER
btw, tabata isn't a exercise per se rather it is a protocol that can be adapted to most exercises like burpees, hindu squats and so on
again, google "tabata protocol" for more information
also, If you consider trying tabatas, I totally recommend one of this interval timers
www.gymboss.comfurthermore, I wouldn't even dare to try the full 8 rounds my first time around
start off with 4 and add around every week or two till you get to the full 8
trust me, even at 4 rounds/2 minutes, this workout is certainly where it is at
