Congratulations on finding your treadmill and starting to move! I'm with you. I am on third level with my Gazelle (sort of a ski machine with pistons for different levels). I was using it up to 1 hr. a day but then moved the resistence level up and am now doing 30 min. I'd rather sweat more and get it over more quickly. After my holiday food abuse I sure need the movement as well as new resolve with my food plan.
