Improving body image is a process of breaking down self-criticism and changing one's belief system. Self-selling positive thoughts is the first step in overcoming the negative and focusing on the myriad of wonderful attributes that most people have. Associating with positive people, focusing on being more tolerant, compassionate, and understanding of others are great self-appreciation tools. Exercise has been shown to have a positive effect on body image and mood. Exercise may allow one to view their body as an amazing functional machine, as opposed to merely decoration.
Exercise promotes weight control, is associated with less depression and a greater sense of control.
That's smart exercise - exercise with a realistic goal in mind. Exercise with an exaggerated focus on the body may contribute to an even greater level of body dissatisfaction. Remember that genetics plays the largest role in our appearance. Our DNA maps out a certain body type and we work within our inherited parameters. Making the best of the genetic map is the fun part.
