I love so many like you! I have to have variety. I can't do a whole week of the same. I like kickboxing to punch out the stress, Zumba to feel like I am not working out just clubbing, and anything Jillian with strength training/circuits/, also HIIT workouts to tone and become stronger and leaner. I love working out! Lastly, I like Walk Away The Pounds with Leslie Sansone to take it easy when my knees are acting up and to take up a notch when I do that video I use dumbbells for my upper body.

I can't stand the typical workout like going to the gym to do the elliptical, using the machines, etc. I've tried it before and just get bored. I have to do things that are dance based. I used to do musical theatre and danced a lot. I alos bellydanced for about a year and a half, which I ended up getting burnt out on since I waas teaching 3 days a week, having rehearsals for shows, then needing to be home with a puppy, and started my master's degree. Now, 2 years later, I'm trying to find the right workout. I've tried Zumba and it just wasn't for me, not enough structure to it and too much hip-hop which is completely foreign to my body. lol
So far I'm starting with Tracy Anderson's Mat workout and am going to try her dance cardio DVD.

I absolutely love love love love loveeeee biking

Zumba!

Definitely yoga and weight lifting.
I run/go on the stairmaster for 45 minutes a day but I get bored easily.

Anything bodyweight! My favorite classes are boot camp style and I love running and hiking.

The nonexistent kind! Hahaha just kidding :P If I do manage to get off my lazy butt, I typically walk on an incline, use a stationary bike, or jog.

I have to say yoga is my biggest one, but I love to walk too. It helps clear my mind like yoga does and it's a nice feeling to have a clear mind and such.
Recently I've started learning ballet and belly-dancing. Those two rank close to the top of my list as well.

Weights (especially legs) And stretching after running!
