Do it for. the stares the whispers that bikini the collarbone the hipbone the gap between your thighs the belly shirts the melted sweaters the light-as-a-feather feeling the cute pictures the sexy lingerie and most importantly YOURSELF
Sometimes a reality check is the best kind of motivation. Weight gain can lead to any number of health concerns. You don't have to be sixty pounds over weight for this either. Every body type is different. The one thing that is certain is that exercise can help at any level. Even just 20 min of cardio a day. Don't go crazy, but don't stop caring. WORK TO MAKE THE ONLY BODY YOU HAVE THE BEST IT CAN BE.
