I had a rowing maching many years back.... when I was just a young pup! It was a great all body work out. But right now, for me, I wouldn't try it, because I know how hard it is and know my present limatiations.

But, having said that, it might work for you... just know it is a fully body workout and very hard! And I was in really good shape at the time and still found it challenging.

Not trying to discourage a workout, just giving my experience. Good luck finding what works for you. But, just an afterthought, you might try to find one just to try out a few times...... I can't remebmer, it might have tension adjustments on it, and maybe I just had it set on a hard position.
