Cork and I are doing at least one yoga/pilates class per week now. plus we bicycled the other day (almost killed me). and plan to do exercise on our own at home as well.
as far as diet and weight reduction, we haven't really gotten very far. I'm reading two current resources for motivation and just general info: Body for Life for Women (A Woman's plan for Physical and Mental Transformation) - Pamela Peeke, MD, and The Reality Diet (fight fat with fiber) - Schnur, MD. They are both really straightforward, no nonsense approaches to weight loss - and include a lot of info on weekly menus, exercise, etc.
I know that I will need a menu plan to follow in the first 3 months of my "transformation". If I have a reasonable menu to follow, then I don't mind shopping and cooking. Having it all planned out makes it easier for me, and it makes me eat things that I would otherwise avoid or not think about eating (it expands the culinary experience)...
What are your goals? I need to finish up some of my reading and then I plan to put my goals on paper, along with my plan to achieve them. I have also already started a food and exercise journal.
I'll be sharing some of this with you. I hope we can all share successes, questions, recipes, exercise tips, etc... hope to see you on here every day looking for motivation and at the same time giving support to all of us..

. NOW for the 1st time in my life I think I am TOO thin, have been and had tests done etc. to make sure there wasn't anything medically wrong with me...........it's just WEIRD, since I have sturggled with my weight for 20 plus years, now BOOM..............I'm TOO thin now (especially for my age) Oh well.........but i know I'm not in shape, I need to excercise more, and maybe that will put some muscle weight on. 
mr. dd just had to have mexican..uh, hispanic uh, latino no....it was mexican. anyway i had a fajita salad with beef fajita strips, salsa, and low fat thousand island. I coulda made something at home, but that's what he wanted. But, I guess it's better than the enchiladas I would normally have ordered. I did eat about 6 chips---usually can eat a whole basket!
Glad you had funn on your cruise and that you missed the outbreak!
that mr. dd bought a while back, brown rice, mixed veg.
