Last night all the treadmills where taken and the only one available was broken :( So I jumped on the elliptical machine. . . . I stayed at a nice quick pace for about 15 minutes. My thighs and butt definitely felt it!! I wasn't sure I would be able to walk today or not, but I must be in pretty good shape cuz I don't really feel it much. I guess I should do it longer next time. I was just exhausted when I quit last night. Well I jogged to the gym and then cooled down by walking home. It was nice.
