Combining cardio and strength training can significantly benefit fitness goals by enhancing both aerobic fitness and muscular strength. Cardio exercises, such as running or cycling, improve cardiovascular health and endurance, while strength training builds muscle and boosts metabolism. This combination can lead to increased fat loss, better overall physical performance, and improved body composition. Additionally, alternating between these two types of exercise can help prevent boredom and injuries, making it easier to stay committed to a workout regimen. Ultimately, this balance supports a more well-rounded fitness journey.
