Mind-muscle connection can boost strength and power
Share
Introduction
What if improving your workout performance wasn’t just about how heavy you lift—but how deeply you focus? Recent research has shown that combining mental effort with physical training—what’s known as the mind-muscle connection—can significantly increase strength and power. By imagining the movement while doing it, athletes can train their brain and body together for better results.
What Is the Mind-Muscle Connection?
The mind-muscle connection is the practice of consciously focusing on the muscle you're working during exercise. For example, when doing a squat, instead of just moving through the motion, you concentrate on how your leg muscles are stretching and contracting. This technique isn't new to athletes, but science is now proving how powerful it really is.
In this recent study, athletes used a method called motor imagery—mentally visualizing the exercise—while physically performing the back squat. This combination helped them build more strength compared to those who just did the exercise without the mental focus.
The Study: Thinking + Lifting = More Gains
Researchers worked with 100 experienced CrossFit® athletes over a 7-week training program. They were divided into three groups:
- One group imagined the lifting phase of the squat (called the concentric phase) while doing the lift.
- Another group imagined the lowering phase (called the eccentric phase) during the actual movement.
- A control group did the same squats but without any mental imagery.
All athletes performed the same number of sessions, with the same training intensity, for five weeks.
The Results: Stronger Minds, Stronger Bodies
Both groups that used motor imagery saw bigger improvements in strength (measured by a 5-rep max squat) and power (how fast they could lift the weight) than the group that trained without mental focus.
Interestingly, the group that focused on the eccentric phase (lowering the weight) showed even greater strength gains than the concentric group. However, they also felt that the mental training was more challenging and required more effort.
Why This Works: Training the Brain Too
When you imagine a movement, your brain activates the same areas as it would during real exercise. This mental practice strengthens the communication between your brain and muscles, helping you perform better physically. Over time, this “neural training” improves how your body recruits and controls muscle fibers.
So, just like your muscles grow stronger with use, your brain’s control over those muscles can improve with focused mental practice.
How to Use This in Your Own Training
You don’t need to be a pro athlete to benefit from the mind-muscle connection. Here’s how you can add it to your workouts:
- Slow down and focus: While doing an exercise, concentrate on the specific muscle group you're using.
- Use visualization: Before and during a rep, mentally picture yourself moving through the motion with perfect form.
- Breathe and be present: Don’t rush through exercises. Focus on each phase—lifting and lowering—with intention.
- Try it with bodyweight or resistance training: Exercises like squats, push-ups, or bicep curls work great for this technique.
The Takeaway: Train Smart, Not Just Hard
This research shows that mental focus during exercise can be just as important as the physical effort. Building a strong mind-muscle connection helps improve performance, boost strength, and even make your workouts more effective.
So next time you hit the gym, don’t just count your reps—make every rep count by engaging both your body and your brain.
