It really feels in my body like running + weightlifting for about an hour and a half. That is what I was doing about a year ago to get the same results I am getting today.
I don't know, maybe I was expecting more given the article, but I'm sure even 7 minutes a day go a long way when it comes to feeling better and energized. I'm still skeptic about the claim that you can swap an hour-and-a-half long routine for 7 minutes worth of intense training.
