Hi -- thank you all for your replies so far! You've mentioned ones I didn't know about, plus a few I did know of but forgot.
I also remembered one more: Fight Age With Strength with Margaret Richard.
I'm specifically looking for upper body workouts that would not unduly stress my elbow. Band exercises might be an option, although I think it would depend on how they are used. For example, standing on one end of a band and doing a biceps curl with the other end would be an example of the kind of exercise I'm trying to avoid.
I appreciate the input -- if anyone else has suggestions please keep 'em coming!
