But you have to remember. Most people that are out of shape physically can not start doing HIIT until they have built up some sort of endurance, something cardio helps with if your doing it right. For people starting out, doing cardio along with your weightlifting is a good step towards future progress. If you were a fatfuck, do you think you could run for 20-30 secs 10 times in a row and not have a heart attack?
