Answer:
When exercising for muscle strength, you should isolate the muscles to be strengthened; carry out the correct motion fully in a smooth and controlled manner without other muscles compensating. People tend to compensate when they are tired, which is when other muscles take over for the fatigued muscles. When you are exercising, be mindful of this tendency and make adjustments in resistance in order to isolate the appropriate muscles. Whenever possible, exercise a joint through its full range of motion so as to work the entire muscle and not to use too much weight or resistance during the end of a motion.
