Strength training can significantly affect body composition by increasing muscle mass and reducing body fat. As individuals engage in resistance exercises, their muscles undergo adaptation, leading to gains in strength and increased metabolic rate, which can enhance fat burning even at rest. Higher muscle mass contributes to a leaner appearance and improves body metabolism, ultimately aiding in weight management. Additionally, strength training can improve bone density, functional performance, and overall physical appearance, further encouraging adherence to fitness programs and promoting a healthier lifestyle in the long term.
