OMG tired. At least the weights seem to be doing some good! :D I got The New Rules of Lifting for Women, after seeing several recommendations for it online, and decided I liked enough of its philosophy to follow along with the program. (The trainer guy prefers to do fewer exercises that work a whole lot of muscles at once, rather than concentrating on one muscle or muscle group at a time, unless you're training for bodybuilding. I am all about getting it over with as fast as possible!)
It came on because of the need to strengthen my bones, plus wanting to build more muscle up as it burns more calories. :) But I will be happy as long as I make my bones stronger, although that will take months, I think, as I believe bones take a very long time to respond to repeated stresses like weightlifting.
