Weight training can positively impact cardiovascular fitness by enhancing overall muscular endurance and efficiency, which can improve performance during aerobic activities. While primarily focused on strength, weight training increases lean muscle mass, which in turn raises resting metabolic rate. Additionally, it can improve insulin sensitivity and enhance blood circulation, promoting better heart health. Incorporating weight training into a fitness regimen also helps prevent injuries by strengthening muscles, tendons, and ligaments. Thus, a well-rounded approach that includes both weight training and cardiovascular exercise offers comprehensive benefits for overall fitness.
