The classic elliptical trainer can be quite bulky, so depending on the size of your home you will have to choose between an elliptical trainer or a foldable elliptical trainer. The foldable elliptical trainer, as the name suggests, folds up and therefore allows the user to find space once the session is over. The only real benefit of using a foldable elliptical trainer instead of a conventional elliptical trainer is to save floor space. This type of elliptical trainer is ideal for people who already live in limited space (studio, small apartment) and want to be able to store their equipment without taking up too much space.
