Misconception: If I lift weights, I'll put too much stress on my joints

FACT: Actually the opposite is true. Joints become healthier with resistance training.

Obviously overloading a joint can lead to injury. However, an appropriate program of resistance training, combined with reasonable progression in weight, range of motion, and proper technique can be the best thing to increase joint stability.

Simple movement or articulation of a joint provides nourishment by increasing blood flow to the joint you are working. Furthermore, the resistance strengthens the connective tissue (ligaments and tendons) which maintains the integrity of the joint and helps to prevent injury. Joints without consistent resistance training are weakened and vulnerable to injury.
