Divy Amin is a certified fitness trainer who thinks that cardio and weight training, both have their own benefits. Weight training is essential for your muscles and your metabolism. As you build muscles you increase your metabolism and your core gets strong. Cardio is also important to have a healthy heart which is a vital muscle, and the only way to work this muscle is with the help of aerobic exercise. Cardio helps your heart pump the blood more efficiently, so it can lower the chances of heart disease and reduce blood pressure and high cholesterol. More Importantly, both the exercises should not be performed on the same day in order to get more benefitted.
