I'm with lifesaver... I only run if someone is chasing me.
Actually, I enjoy walking as a form of exercise more than running. Less strain on my legs that way. I also use my ab-sizer and my stair master for workouts. However, I've gotten out of my routine because I've been so busy lately.
Hopefully, after the holidays, I'll be able to do more. I've asked my boyfriend to fix up my old bike as a Christmas present (it needs new tires and some general maintenance after sitting in the basement for several years) so I'm looking forward to riding my bike again, too!
