The main thing in sports is endurance

You can be strong, fast, dexterous, but all these qualities will not pay off if the athlete does not have pumped up endurance! For example, a boxer can simply “take a breather” from his tough “knockout” opponent, who will lose all his explosive power at the beginning of the fight. Therefore, the most important goal of any training in sports is to harden the respiratory tract. Cardio, cardio and more cardio! But you understand, the main thing is not to overdo it. If you feel that you have reached the limit, press pause. For example, this charming runner did just that. Health is more important.
