Doctors were shocked by a recent case of a citizen in Henan, China, who developed pneumothorax (a lung disorder) after doing 20 push-ups.
The unidentified man told doctors he decided to get fit as part of a New Year's resolution.
He said that last month he started doing push-ups and jumping rope to lose weight, but he started feeling sick after doing only two sets of push-ups and jumping rope.
He stopped and became engrossed in his daily routine. But when he woke up the next day, he experienced severe chest pain and difficulty breathing.
He went to the hospital where doctors diagnosed him with pneumothorax. This is a condition in which air gets trapped between the chest and lungs.
