We are always looking for shortcuts in our fast-paced lives. Exercise is no exception, hence the popularity of High Intensity Interval Training (HIIT). HIIT involves alternating high intensity bursts with recovery periods at lower intensity. I used to exercise with a mentality of “more is more”, and if I didn't work out for at least an hour, then it wasn't worth exercising at all. Now, with less time on my hands and a better understanding of human physiology, I’ve discovered, happily, that Less is More.
