Mind-muscle connection is a conscious and deliberate muscle contraction. It’s the ability to focus the tension you create during exercise on a specific muscle or region of muscles in the body, which is the difference between just moving the weight and using a specific set of muscle fibers to move the weight. 

When you focus on using specific muscles to create contractions, the brain calls on a greater percentage of muscle fibers to complete the task. This also prevents engagement of muscle fibers not in use. By creating tension in the right muscles, your body is better able to gain strength and size in all the right places.

Focused attention is how well the brain can concentrate on a specific activity for a given amount of time. This is a large part of cognitive development and works well during resistance training. 

To improve your mind-muscle connection, focus your attention on the muscles required to move the weight. Make a choice on which muscles you want to use for moving the weight. We can do the dame movement over and over yet target completely different muscle fibers each repetition.
