I'm one of those who had to take some time off due to health issues. (Burning calories unnecessarily = last thing I want to do.) But since resistance training is reportedly not that good for losing weight anyway, I've been ramping it up again with the hand weights over the last few weeks, and have gotten back to doing my previous "light" workout (7 sets of 16 reps each of assorted exercises using 10 pound weights, or 7 sets of 10 reps each with 15 pound weights, plus non-weight stuff) reliably every day for about a week... which I guess means that I wasn't losing that much muscle. Or maybe that I'm just really stubborn. I dunno. Want to work up until I'm doing those 16 reps with the 15 pound weights, at least, then I'll figure out where to go from there.

Side bonus - doing a couple of sets right before bed seems to help me sleep through the night without being woken up repeatedly by the panic attacks that have been plaguing me. And even when I do get woken up, I can control them quicker. Hooray for weights! And here I had heard that exercising at bedtime would keep one awake...
