Hello, I am Shana and trying out this group thing. I am 41 years old and have hypothyroid. This makes it a little more difficult for me to lose weight when I am not medicated properly but currently things are going well with it. I currently weigh 185 and would like to weigh 140. I am a ballroom dancer (hobby) and want to look good when I am competing. I do that often plus I workout at a cardio trampoline/yoga studio. I am eating 1200 calories a day and am going to try double workouts when I return from Oregon. I want to try a yoga class and a cardio class each day. (I am a teacher so I am on summer break and thought doubles over the summer would be worth trying). Anyone have any thoughts or tips? It seems like my body loves to stay in the 180's so I am always battling to get below them and then it is a struggle to keep my body from going back up to that number again once I lose.
