As we talked last night, you should look into one of the gyms you mentioned. Exercise is very important for good tone and general health. Don't sweat about getting too much muscle. That won't happen, and besides, it isn't like things will happen overnight.
Post your meals, like what things you eat and at what time of day.
check out the articles of interest forum, and the female fitness forum. Theres a lot of info here, and very knowledgeable people.
As you get the diet and exercise routine going, the shape and tone will come... 35 is definately not too old to start getting fit.
