Our ongoing article series comparing HIIT with cardio really got my attention. As a semi-regular gym goer (3-4 times a week) I have got myself into a very stale pattern, in terms of cardiovascular work.I usually get on the treadmill, do a short warm up, then just plod along at a steady state speed. If I am honest with myself, I never venture out of my comfort zone. I often get quite bored running at steady state, meaning I end up quitting before reaching an adequate exercise duration which is why I thought I should give some HIIT a bash
