It didn’t take you a week to put on all that weight, so naturally you won’t lose it in a week. Results take time, dedication, and discipline to achieve. And your body typically won’t change drastically enough for you to see results after the first week or two of working out. But don’t get discouraged! Even though you may not see it on the outside, your body is changing on the inside with every effort you put in! So don’t give up. After the first month or two you should be able to see visible changes to your body, and more importantly your health and fitness.
