"You can do anything for 20 seconds." You might have heard that line in a workout class or on Daily Burn 365, when a trainer wants you to focus on an exercise, drive through the burn and push past what you think are your limits. Well, there’s a reason they want you to go short but hard. You only need to push at your max effort for 20 seconds to conquer a Tabata— a training technique founded by scientists back in the late 90s. Research still says this method improves your VO2 max and offers mega cardio benefits, not to it mention blasts calories fast.

Tabata workouts—a form of HIIT—specifically involve putting in 20 seconds of serious work, then resting for 10 seconds. You repeat this work-to-rest ratio for eight rounds. (Yes, that means you can get a solid workout in just four minutes.) Better yet, you can incorporate almost any exercise into a Tabata format (as long as you’re going at an intense effort), and you don’t need weights or a lot of space.

So, still thinking you have no time to squeeze in a workout? Put this total-body Tabata workout, courtesy of Daily Burn 365 trainer Prince Brathwaite, to the test today. You won’t even have to leave your living room.
