I had some knee problems earlier this year, so I used my tax refund to buy a Life Fitness X7 - nice elliptical.

Then this dang back injury happened and now I'm wondering if there's any hope I can get back on it. I haven't addressed this directly with my PT yet - but I'm thinking they're going to try to push me to the next level which might involve my elliptical.

So my question - in your experience would an elliptical machine put far too much stress on my back muscles and abdominals? Should I just slow it down a touch?
