Hi I'm also new to this app. I'm 54 , overweight, suffer from thyroid problems. I like a couch potato sitting on the sofa watching tv. I know I need to change those habits but the idea really scares me, I'm not really fit for exercise, I go to Zumba class just once a week and the rest of the week take several walks with the dog. I know that I should stick to the program. Hope to start tomorrow.
