If your daily cardio lasts for more than 60 minutes, it may impact your health. Athletes who do more than 10 hours of intense cardio in a week can damage their heart, which may never get healed.
When good exercise goes bad
Doing cardio is beneficial as it raises your heart rate which in turn raises the amount of oxygen in the blood. It also increases endorphin that acts as a natural painkiller. Aerobics, which is also a type of cardio, strengthens the immune system, helps to pump your blood more efficiently and increases stamina. But stretched cardio session may harm your body that can lead to negative effects like:
Reduced metabolism that hampers weight loss:
Whenever you exercise, it burns both fat and muscle. But the amount of muscle you burn is minimal. Doing cardio in excess can increase the risk of more muscle burn. This happens as the body struggles to keep up with the increased level of energy. It weakens your metabolism and hampers the process of weight loss.
