I would not call it disadvantage but a special consideration:
For some people with hip problems, be it a hip replacement or something like hip displasia, the fixed width between the foot pads can present a problem. You can see them turning their feet out and often extending over the pad perimeter. However, this comment does not apply to a majority of people with hip issues.
Similarly, if pepole are of particularly short stature, the elliptical trainer may not be a good choice.
These are the only cases where I found an elliptical trainer not to be a good option.
I guess it would depend upon the level of conditioning of the client, whether they had any orthopedic issues.
I actually enjoy using the elliptical. I don’t use it often but I prefer it to the treadmill.
When my schedule allows I will also go for a test drive on this elliptical. I am in no way a dealer for the product. It simply excites me.
Let me know what you think. Thanks.
