Resistance training positively affects metabolism by increasing muscle mass, which in turn elevates resting metabolic rate (RMR). More muscles mean more calories burned even at rest, promoting effective weight management. This type of training enhances muscle strength, endurance, and bone density, contributing to overall physical functionality. Furthermore, resistance exercises can improve insulin sensitivity, aiding in blood sugar control. Regularly incorporating resistance training into a fitness regimen can lead to long-term changes in metabolic health and enhance overall well-being.
