A cross between an elliptical and a stepper makes this a unique exercise. Don't fool yourself, this is not elliptical. Since Freemotion markets it as such we have included it in our ratings. Make sure you try it before you buy it because it is a very different exercise.
The s5.6 is a pseudo-elliptical that has been on the market for about a year and a half. During that time they have not made a lot of headway with the unit. It has a fairly awkward motion that only an engineer could love. Obviously we are not real high on this unit. That doesn't mean that it won't hold up well, it looks like it will. The workout is so tough, however, only a special forces soldier or a real masochist will like it.
