Corrective training program include stretch and strength training for eight weeks duration. Dedendent and independent t - test was used for Statistical analysis of data. Findings of this study showed that lumbar lordosis in experimental group significantly decreased. In addition, strength and endurance of abdominal muscles and flexibility of back muscle increased significantly, but changes in lateral range of trunk motion and flexibility of abdominal muscle was not significant. In other hand in post-test there was a significant difference between degrees of lumbar lordosis and endurance of abdominal muscles of experimental and control groups (p≤0.05).
