Fit's Tip: Be careful getting on and off the TreadMill as it will still be moving. Also, this workout is not one that would work well in a crowded gym, especially if there are people waiting to use the machines. If this is too hard (or easy) adjust the incline and/or speed to fit your level. Check out this other great TreadMill walking workout.
