Abstract

Background: Obesity^s health risks require effective treatment. Muscle strength and weight loss can be improved with resistance training. Resistance training with gym machines for obese women has little study. This demographic can work out safely using gym machines. The effects of gym-based resistance training on muscular strength and BMI could inform personalized therapies.
Purpose: This study aims to investigate the impact of resistance training utilizing gym machines on muscle strength and Body Mass Index (BMI) among obese women.
Methods: The one-group pre and post-test involved 30 obese women aged 17-25. Resistance training was assigned. Resistance training entails using gym machines to target main muscle groups thrice a week for ten weeks under supervision. Lat pulldowns, stomach crunches, cable curls, chest presses, and leg presses are used. Height and weight were used to compute BMI, whereas the one-rep maximum (1RM) test measured muscle strength. Then the paired sample t-test effect was examined.
Results: After the 10-week intervention, the resistance training group showed a significant increase in muscle strength across all exercise measures (p < 0.05). In addition, the resistance training group showed a statistically significant reduction in BMI (p < 0.05). These findings suggest that resistance training using gym machines can effectively increase muscle strength and contribute to lowering BMI among obese women.
Conclusion: Finally, resistance training on gym machines can boost muscle strength and lower BMI in obese women. This study shows that systematic resistance training can improve this population^s muscle fitness and weight control. These therapies^ long-term health and well-being impacts can be studied.
