N.C.
What I want to add is that I wouldn't advise you to get the manual treadmills, you know the one's that don't have a motor. I got that one at home and I have to put oil on it, and I have to move it myself, and that is very very hard to do. If you are going to get a treadmill make sure it has a motor. Now I am going to bally's to work out, using their treadmills works out better for me.
This advise is coming from a mother of three trying to get her body back in shape.
