Im trying to get my home set-up built out and basically have a rehab center at my house.

I already have equipment that I use regularly and am wondering if this is enough or I should add something

Right now I have a nordictrack freestryde fsi14i (elliptical) and I also have an exercise bike.


Specific questions:

I know everyone uses the bike but could the elliptical be useful too, of is this too odd of a movement to be helpful?  Is getting a cheap treadmill a better idea?

Anything else that helped you get your walk/gait correct?
