so there's the one minute on one minute off and you do that 10 times so that the 10 the 10- minute workout well it's actually 20 minutes but 10 minutes of more high-intensity um training where again for that entire minute you're going as hard as you can sustain for that minute right it's not going to be all out but it's as much as as hard as you can go and sustain that for a minute and then you rest and recover for a minute very very low intensity exercise
