That's a good point. And then if you find something you love so much that you want to go (and go hard) every day, get some advice from someone more experienced. Too much is often detrimental, even if you think you feel capable of it. Ideally you can end up with a mix of weight building activities and cardio activities. As people elsewhere have mentioned, playing sports can be a really fun way to get cardio without "doing cardio". Same goes for dancing or regular good sex.
