When you’re looking to transport a treadmill in a car, the first thing you need to do is figure out how much space you have. If your car has no room at all for the treadmill, then you’ll have to find another way to transport it. If your car has enough room, then you can place the treadmill on top of one of the seats or on one of the cup holders. You can also place it in a small storage area or in a closet if there’s enough space.
