Resistance training positively impacts body composition by increasing lean muscle mass and reducing body fat. Engaging in strength training stimulates muscle hypertrophy, which elevates the body’s basal metabolic rate (BMR), meaning that even at rest, the body burns more calories. Additionally, resistance training aids in changing the ratio of muscle to fat in the body, enhancing physical appearance and strength. Incorporating this type of training into a fitness regimen can also improve bone density, reduce the risk of injury, and enhance overall physical performance through improved muscle function.
