It is a common fallacy that running is bad for your joints and accelerates wear and tear. There is, however, no real scientific evidence of this. For the most part, this line of thinking is not true. If done excessively, running can violate your health, though not really your joint health. It actually has greater impact on muscle health and it can accelerate muscle wasting if dosed incorrectly. Done in the right amount, it can be a great way to maintain your running skill and running fitness. Rarely anymore do people need to completely stop running. Most often, adjustments in volume or intensity enable people to continue running productively.
