I used to really enjoy getting a variety of workouts, like P90X, Insanity, and super light things like cardio machines at the gym (elliptical, bicycle). I've given crossfit/weightlifting a go as well, but I'm unable to make the class at my local gym due to work. I also love doing zumba, but my feet start hurting so much. I did the DVDs to get me started, but once I was finally coordinated enough to do it in public, I started going to classes. Alas, I never seem to lose much weight, though, and it gets so, so discouraging, even though I (generally) eat well.
