> with 7 minutes I barely broke a sweat. Unless you're morbidly obese you need to do more than this I'm a twig who eats averagely and does no exercise other than walking everywhere (around an hour a day) -- I break a sweat after ~3 minutes and collapse on the floor panting at the end of the 7 >_> I'm pretty sure that it is helping, because now I can actually do the full 7 minutes, where a few months ago I would only manage ~20 seconds of activity out of each 30-second burst before I fell over from muscle pain. Are you sure that the specific numbers of minutes are what's important? I am by no means an expert, but I was hoping that "push every group of muscles to their limit every day" would be enough...
