I walk 2-3 miles a day using Leslie Sansone's WATP DVDS and I'm careful about what I eat. I eat low-fat protein, dairy, fruits and vegetables and only whole wheat breads. A friend of mine who used to be the same size as me started eating the way I do but she doesn't exercise at all. She has gotten smaller all over her body while my back side seems to be getting bigger every time I walk my miles. I really enjoy exercising with Leslie Sansone. I always feel better afterwards. But what am I doing wrong if I'm not seeing the results I want?
