How does resistance training affect body composition?

Resistance training is a well-established method for improving body composition by increasing muscle mass and reducing fat mass. Engaging in resistance exercises, such as weight lifting or body-weight workouts, stimulates muscle hypertrophy, which is the process of muscle fibers enlarging in response to the stress placed upon them. This leads to an increase in overall muscle mass.

Simultaneously, resistance training has a metabolic impact that can aid in fat loss. Increased muscle mass elevates resting metabolic rate, meaning that the body burns more calories at rest. This enhanced caloric expenditure can contribute to a reduction in body fat over time, provided there is a caloric deficit or a balanced diet is maintained.

The combination of increased muscle and reduced fat not only improves overall body composition but also brings about enhanced physical performance, strength, and improved health markers, such as better insulin sensitivity and reduced risk for chronic diseases. This multifaceted approach to body composition highlights the effectiveness of resistance training in achieving a healthier body composition profile.
