I am really starting to stress out, my wedding is in less than a year! I haven't been to the gym in over a year and I don't know how to start. I don't want to start going and get frustrated because I am doing things wrong. I like to swim and do yoga because due to health problems I can't do any other kind of exersice. Do you guys have any tips on how should I start and how many days a week I should start going.
