Optimizing Health Outcomes: The Impact of Circuit Training Programs in Reducing Obesity and Improving Body Composition

This study aims to evaluate the impact of circuit training programs on reducing obesity and improving body composition, including weight loss, body fat percentage, and Body Mass Index (BMI). The method used was a quasi-experimental design with a pre-test and post-test design on 30 obese participants who underwent an exercise program for 12 weeks. The program integrates strength and cardio training with a gradual increase in intensity. The results showed that circuit training significantly reduced weight, especially in the group that used additional weight (free weight). However, the decrease in body fat percentage and BMI did not show significant results in a relatively short period of time. The suggestion of this study is to combine circuit training with the right nutrition approach to accelerate body fat loss. In addition, more comprehensive health monitoring, including waist circumference and body fat percentage measurements, needs to be applied to get a more accurate picture of changes in the body composition of obese people.
