How do you work out?

I've been thinking a lot about workouts lately. Probably because I have no more classes until mid-September and that gives me a lot more time to think about getting healthy. Maybe because I spoke to my mom the other day and learned that over 75% of her parents' generation have died of heart disease related conditions (eek) or cancer. Also, probably because it's hot now and I feel like the Pillsbury Doughboy in my tank tops (not to mention bathing suits). So today I thought we should discuss working out.

I'm not super structured when it comes to working out. I don't have a training plan, I just tend to work out when I feel like it and leave it there. Right now my work outs look a little like this:

Running: I've always been a runner. I was in track in highschool (800m, woot) and I never really lost running as a hobby, though I run more sometimes than others. Right now I run probably 4-5 days a week, depending on how stressed I am (I actually run more when I'm stressed). Usually my runs are pretty casual- I'll head out with my ipod and just let my feet lead me wherever until I get tired enough to turn around. Most of the time I don't even time myself. When I have glanced at the time, my runs are usually between 30 and 45 minutes in length, so not super long but not terribly short either. How hard I run usually varies too- I run faster when I'm stressed and slower when I just want to enjoy myself. In case you can't tell, I'm super casual about my running, and I get to wondering whether I should start planning out my runs better. But I've learned that when I plan them, they start to feel like a chore.

Yoga: This is something that I picked up last spring, when I took a yoga class at my university. For awhile there, I did yoga almost every day. It was amazing for muscle tone and posture, two things I struggle with (not to mention obvious psychological benefits). I've let my yoga slip away lately, to the point where I almost never do it anymore. But it's something I hope to bring back over the summer when my schedule is (hopefully) less hectic. Anybody know of any good yoga DVDs?

Rock Climbing: Okay, so this is something I just started doing once a week as of two weeks ago and already I LOVE it. I'm pretty lucky in that my university has a huge climbing center not too far away from me, and I'm thinking of buying a rec pass just so I can have access to it over the summer. Rock climbing is a great upper body workout for me, namely because I have almost no upper body strength. Not to mention, it's just plain fun. I'm encouraging all of you who have access to a climbing wall to give it a shot- I'm planning on going once a week over the summer if I can get ahold of a rec pass.

Those are pretty much my three primary workouts right now. I'm also thinking of picking up swimming over the summer, especially if I do get a rec pass, since my university has several swimming pools as well. What are your favorite workouts and how do you stay healthy? Got any fun suggestions for me?

PS: Thanks for all of your well wishes last Thursday as I went in for my job interview. I got the job! So now I'm a sales associate and fitting room attendant at a large department store in addition to my usual part time job, which means I can actually pay my rent over the summer. Woohoo!
