Resistance training positively impacts insulin sensitivity by enhancing the body's ability to use glucose effectively. As muscles work during resistance exercises, they become more adept at absorbing glucose from the bloodstream, aiding in blood sugar regulation. This effect is beneficial in preventing or managing type 2 diabetes and is particularly important for those with insulin resistance. Regular resistance training also promotes muscle mass retention and fat loss, further improving metabolic health. Consequently, incorporating resistance training into fitness regimens can lead to significant enhancements in insulin sensitivity.
