My gym says we should get cardio exercise at least three and preferably five times a week for 30-45 minutes. I have heard this elsewhere and they don't get any more money if people come more often, so I'm guessing this is "the word"

But I don't manage that (or at least I didn't), and I'm a "SAHM" -1-2 times/week was more the norm for me. And I tested as "fit" today. My friends don't exercise anything like as much as me (they don't eat and drink as much either). Are they destined to face a decrepit old age? or are these guidelines bullshit sponsored by Nike etc? Let's assume I don't need to lose weight and am fit -why do I need to exercise so much? because I'm pretty sure most of the population doesn't and yet the average lifespan is still increasing.
