Being overweight no matter whether it is fat or muscle is bad for you, it increses stress on your heart.
To a certain extent an amount of overweight in muscle is good, though deviating from a healthy BMI too much whether it be from muscle or fat greatly increses risk of heart attacks and diabetes.
The human body is susceptable like most things in the world to wear and tear, which is why atheletes do not live as long as a person doing light but regular excercise.
Taking that in mind the BMI is not all THAT bad to judge people from although there could be some corrections under certain circumstances .
BMI fits the average population well so there is no need to change it + cant you just measure your weight and not used the BMI if you dont care for it?
Endure. In enduring, grow strong.
