The reason it is wrong is that the filter through which we must look at general health knowledge (YOUR LIFE) tends to renders what might be healthy for one unhealthy for another and ANOTHER today means most business leaders.
Long bouts of cardiovascular exercise (over 20 minutes) might be beneficial for someone but it also increases stress hormone release and reduces muscle mass.
So if you are already experiencing symptoms of stress such as constant worry, anxiety, stomach fat, low energy, alcohol dependence, excessive phone usages, poor sleep to name a few then cardiovascular exercise is likely ANOTHER coping mechanism that will ultimately if not immediately do more harm than good.
