The mind-muscle connection is a concept from bodybuilding circles that made it into exercise science. The mind-muscle connection refers to our ability to sense how well a muscle is being trained and our ability to selectively activate our target muscles during an exercise. The idea is that a good neural connection between your brain and a muscle allows you to feel how well you’re training that muscle and thereby adjust your program. For example, a bodybuilder may forsake an exercise because they can’t get a good mind-muscle connection and replace it with an exercise they feel more strongly in their target muscles. The mind-muscle connection is also purported to give us the ability to make our bodies preferentially recruit our target muscles. By focusing on the target muscles while you exercise, you can feel them more, and this is taken as a sign those muscles are activated more.
