Is it true that physical exercise can lead to joint problems lateron?

Partially true. Physical exercise, if done in the proper way and proper "dose", helps in maintaining the joints in health.

However, if one does either too much exercise or does it with improper technique, the joint surfaces rub against each other, thereby damaging the joint. This can lead to osteoarthritis later in life.

It must be emphasized that despite the good effects of physical exercise, it is quite capable of doing equal damage if done carelessly. It is advisable, therefore, that one takes regular physical exercise under expert guidance.
