aerobic

Exercise performed while huffing and puffing enough oxygen to keep your cells happy, as opposed to those masochistic anaerobic sprints that leave you gasping like a landed fish. The magic happens when your heart rate elevates but you can still theoretically hold a conversation (though you probably won't want to). Basically, it's the difference between a pleasant jog and running from a bear.
