If you were told you could get fit with just a few minutes of exercise a week, would you believe it? It sounds too good to be true, right?

In this episode Anja Taylor investigates the science behind low volume, high intensity training, and takes on the challenge of going from couch slouch to fighting fit, with just six minutes of exercise a week.
