Lowering the Risk of Heart Disease
Studies show that individuals who practice cardio regularly are 30–50% less likely to develop heart disease. Aerobic exercise also helps reduce inflammation and improve blood vessel function.
Enhancing the Body’s Insulin Response
Cardio helps increase insulin sensitivity, lowering the risk of type 2 diabetes. Regular physical activity improves metabolism and helps regulate blood sugar levels.
Benefits of Cardio for Fitness
Improving Respiratory Health
Cardio workouts increase lung capacity and efficiency in absorbing oxygen, enhancing athletic performance and reducing fatigue during daily activities.
Burning Calories and Supporting Weight Management
Cardio helps burn calories, contributing to a balance between energy intake and expenditure, which supports maintaining a healthy weight.
