A program consisting of core stabilization exercises and physical activity counseling accompanied by physiotherapists will be applied to the study group.

The Six Minute Walk Test was conducted according to a standardized protocol, using an internal hallway with the 30-meter distance marked by colored tape on the floor. Participants will be told that "the purpose of this test is to see how far you can walk in six minutes." Then, they will be instructed to "walk from end to end of the hallway at your own pace, in order to cover as much ground as possible." Participants will be allowed to stop and rest during the test, but will be instructed to resume walking as soon as they were able to do so. Before the walk started and at the end of the 6-min walk, participants will be shown a modified Borg dyspnea scale printed on a card and asked to "indicate your current degree of shortness of breath" on a scale of "0 = nothing at all" to "10 = very, very severe." At the end of the walk, they will be asked if they had experienced any of the following specific symptoms: dyspnea, chest pain, light-headedness, or leg pain, or any other symptoms.

Core stabilization evaluation will be done with Anterior and Side Abdominal Strength Tests, Trunk Flexor Test and Modified Push Up Test. These tests will be performed using a 2 kilogram medicine ball. Test positions are supine and sitting position.

Body components such as body fat percentage, body fat amount, lean body percentage, lean body mass, body water percentage, body water quantity, body mass index are calculated with bioelectrical impedance analysis. The muscle, fat and water ratio of the cases will be evaluated with Tanita Bioelectric Impedance Device. When the device assess the body fat percentage, body fat amount, lean body percentage, lean body mass, body water percentage, body water quantity and body mass index, it offers to us a score as called obesity score.
