Re: cardio question
That varies from person to person depending on metabolism and genetics. You will have to gauge how much you need to do to maintain based on whether you lose more weight (or gain). But for health, 30 minutes 2-3 times a week for maintenance is about right. Doesn't have to be high intensity. Just enough to keep your heart rate up.
