When I started, I couldn't even walk to the mailbox without getting out of breath and my heart pounding. I lost 35-40# just following the food plan, tracking and staying within my points. Then I started exercising. Short walks at first, then longer walks. Then working out with some You Tube videos. Fabulous 50s, Leslie Sansone and Body Project. Also some Silver Sneakers You Tube videos, which are seated exercise and a little bit easier to help ease into exercise, Now I crave it, and I feel sluggish if I skip a day. If I can do it, anybody can. Just start with whatever small amount you're comfortable with and keep going. You can do this! The hardest part is starting.
