For the arms I use light hand weights, about 5 lbs. My current favorite routine is just the 10 minute ball workout (approved by my PT). I do have some jiggle but I also have great muscles. I think bike riding and yoga really help too.
I'm not sure there's much you can do about the bust, depending on what you're starting with. I had so much extra fat in that area and the skin was so stretched out that things are a bit sad now (unlike weight loss results at 30). Losing the weight was definitely worth it but I was a bit surprised at the result of that combination of age and weight loss. Ask in the weight lifting forum though. Maybe some of the Chicks have had luck with more upper body strength work?
