After childbirth, many women experience difficulty losing pregnancy-related weight, which can affect their health, self-esteem, and physical activity. Regular exercise, including Pilates and moderate-intensity aerobic exercises, is considered a safe and natural method to improve fitness and support weight loss during the postpartum period. This study aims to compare the effects of Pilates and aerobic exercise on body weight, Body Mass Index (BMI), and waist-to-hip ratio in postpartum women over 8 weeks. Participants will be randomly assigned to either a Pilates group or an aerobic exercise group, with both groups exercising three times weekly for 45-60 minutes. The results will then be compared to determine which exercise method is more effective.
