So, I'm looking at getting back in shape after being inactive for a year or so. High metabolism and quick dehydration pose a problem. What's mainly lacking is my muscle structure and cardiovascular strength. I want to get my cardio up the most, since I'm fine with my physical appearance and don't have a job that requires heavy lifting or the like. Should I just run, or is there a better method for such? Any pointers for getting back into the groove of things without burning out? And doing so cost effectively, since I'm broke as a radio without sound?
Thanks ahead of time, folks.
