What is the Mind Muscle Connection? How Using Your Brain Can Lead to Serious Gains

Forget your liquid chalk or lifting belt, learning how to implement and improve your Mind-Muscle Connection (MMC) can be one of the best tools to be armed with in the gym for maximum progress and results from your training. 

Many of us have a particular muscle or group of muscles that don’t seem to grow as effectively as others, no matter how often they are trained. Frustrating as this may be, a potential solution to this problem has been with you the whole time – your brain!  

Whilst we often think of ‘brains’ and ‘brawn’ as opposing characteristics, it has been shown that in order to maximise gains and really see the results of your efforts in the gym, both mental acuity and physical strength are necessary.You may have heard sports coaches or PT’s in the gym telling their clients to “squeeze”  a particular muscle during exercises, while you may assume this is simply motivational, these timed cues to focus on a particular muscle have been shown to impact muscle stimulation and hypertrophy (muscle growth). Many professional sports coaches and PT’s use mental cues during training sessions to shift their athletes/clients focus onto specific muscles and movements. These cues can mean that by simply thinking about squeezing a particular muscle during a movement, you activate that muscle much more effectively than just mindlessly smashing out the reps. 

You don’t need to receive these instructions from another person for MMC to be effective. By learning to give yourself mental cues during certain exercises, this will ensure that you keep your mind focussed on the muscle and how the movement feels, rather than how many reps you are hitting or the weight you’re lifting. MMC can mean that additional gains can be made, without increasing weight or reps, and simply by using your mind to shift the focus. Whilst MMC may sound complicated at first, it is essentially a skill like any other which can be developed and improved with practice and time.

What actually is the Mind Muscle Connection?

The mind-muscle connection is an internal focus of attention, which involves directing our attention to the working muscle during strength training. 

There are two types of attentional focus:

  1. Internal focus:
    Internal attentional focus means thinking about what is happening inside the body, such as the muscle you’re working contracting during the movement or thinking about your breathing. Internal focus has been defined as:

“where attention is directed to the action itself” (9).

  1. External focus:
    External attentional focus means thinking about what is happening in the environment around you externally, such as the weight you are about to lift or how many reps you plan to do. External focus has been defined as:

“Where the performer’s attention is directed to the effect of the action” (9).Internal focus has been associated with superior gains in muscle mass and increased muscle activation. In contrast, external focus has been shown to be associated with increased reps in tests of muscular endurance and greater performance on athletic ability tests (2, 3, 4, 5). Whilst it’s clear that there are benefits to be gained from both external and internal focus, if your goal is muscle gain, then internal focus would be the most effective approach to achieve your gaining goals. 

Isn’t this just the latest fitness fad BS?

No, mind muscle connection isn’t just theory, it has been referenced by bodybuilders for decades; Arnold Schwarzenegger himself has long hailed the power of MMC in his training and is quoted as saying:

The Body Is Very Important, But The Mind Is MORE Important Than The Body.”

MMC has since been a subject of particular interest in the sports science world. In fact, there is research over 20 years old in this specific area, evidencing that greater muscle activation can occur when the training participants focus on internal focus during exercise.

Boost your muscle growth by focussing on each individual muscle during training with our top 5 lifting strategies to help improve your mind-muscle connection:

1. Leave your ego at the door and lower your weight:

Yes, we know this may sound counterproductive if gains are your goal – but hear us out on this one. Lifting too much weight will almost immediately ruin any MMC because if the weight is too much for the muscles to handle the connection the muscle cannot be made effectively.Being able to get a heavy weight up is no guarantee that the muscle you are trying to target is being used to its full potential. If you have ever pushed with everything you’ve got to get a heavy weight up, it’s likely that you will have had to pull strength from other parts of your body or altered your form in order to get the weight up.

2. Prime your muscles with activation before each exercise 

Many people make the mistake of diving straight into their workout once they arrive at the gym. However, in order to achieve maximum muscle activation (and avoid injury) you should allow your muscles enough time to warm-up and prepare for the exercises. One of the most effective ways to warm up before resistance training is to stretch out your muscles and warm up the joints. Aside from priming your muscles before training, warming up also helps to improve the circulation of blood to muscles and helps you to experience better MMC. Warm up sets before each exercise with a light weight (or even body weight alone if you are a lifting beginner), whilst trying to really squeeze and create tension in the muscle before lifting heavier weights can be incredibly effective at priming your muscles before lifting to improve MMC. Warm up sets also help the overall quality of your working sets as you can make any necessary adjustments to your positioning or alterations with the weight.

Flexing and contracting the muscles you’re working between sets can also be helpful in developing MMC.

3. Focus on technique and breathing

When lifting, good form is essential to avoid injury and get the most out of your training. Good form is of far greater importance than the equipment you use, the weight you lift and how many reps you perform. The importance of breathing should also never be underestimated. It can be common when forcing out those last few reps to compromise your form and/or breathing. This is counterproductive to successful MMC and ensuring each rep is performed properly will not only improve activation in the muscle you are trying to target, but also reduce the risk of injury.Visualising your muscles pumping and contracting during your reps can be very effective at enhancing MMC. Rather than looking in the mirror, try turning away from the mirror so you’re forced to pay attention to how the movement feels rather than how it looks. 

4. Focus on the movement, not the weight/rep range 

When it comes to executing successful MMC, you need to shift the focus from the amount of weight you’re lifting onto the quality of the reps and track your progress with how the movements feel instead.This may mean a 50% reduction in your bench press to improve your MMC and achieve maximum gains from your training. When you execute good form and technique, heavy weights are undoubtedly effective at increasing muscle mass. However, MMC is key to avoid your progress plateauing and to achieve growth in those stubborn muscles that you struggle to target. 

5. Slow it down and create tension 

Slowing down your reps is a very effective way of improving your MMC and means that isolation movements, such as bicep curls, become much more effective. You will be able to feel your muscles working much harder once your slow your reps down from start to finish. However, you may reach failure earlier than usual but this only exhibits how much harder your muscles were working at a slower pace. Performing your reps at a slower pace also has the benefit of increasing time over tension, meaning that the longer the muscle is under tension, the greater its potential growth stimulus is. Your entire focus should be on the muscle while performing an exercise, from start to finish of each rep. Here’s an example of the pace you should be aiming for, using a bicep curl as the example exercise:

  1. Take 2 seconds on the concentric movement (bringing the dumbbell up to your shoulder)
  2. Pause for 1 second at the top
  3. Take 2 seconds on the eccentric movement  (the force to bring the dumbbell back down)
  4. Pause for 1 more second at the bottom before starting the next rep, maintaining your focus throughout. 

If you’re new to lifting do the same principles apply?

It’s generally recommended that anyone new to lifting spends some time learning how to properly activate their muscles against resistance by flexing specific muscles independently using only bodyweight resistance or light weights to begin, as it is crucial to maintain good form and ensure you are effectively activating your muscles.If you haven’t trained particular muscles before they may have become ‘lazy’ and therefore require waking up before training in order to specifically target them and fire them up! Once you learn how to successfully activate a muscle and feel it ‘burning’ or ‘pumping’, it will become easier to focus your attention on activating the movement in these muscles as you will become familiar with the sensation.

Gains aside, are there any other benefits to using mind muscle connection?

Yes, absolutely! It’s a common assumption that lifting the heaviest weight possible equates to greater gains, however this isn’t the case. Whilst it is true that progressive overloading by increasing weight is important for hypertrophy (muscle growth), correct form and technique are vitally important to avoid injury and get the best results from your training. By ensuring you maintain good form, you can shift your focus from the number on the weight and executing the movement perfectly and slowly – to get the most impact on your chosen muscle.This enables you to get a greater impact from using a lighter weight, which means less stress on your joints. Less stress on the joints means less damage, a lower risk of injury and reduction of deterioration. 

Does MMC work for everybody?

For those strength training with the goal of hypertrophy (muscle growth), the use of MMC can be extremely beneficial for some, but less so for others. For example, complete lifting newbies may find that MMC is helpful during certain exercises, to provide a point of focus to make sure they perform the exercise effectively to hit the target muscle. Several studies have backed this up with research showing that when people were asked to focus on particular muscle groups, this allowed them to successfully activate those muscle groups (1). 

This being said, intermediate lifters might find that MMC can potentially interfere with progressive overload (gradually increasing the weight lifted). This is because intermediate lifters may not be able to increase the weight or number of reps in each set as easily as a complete beginner starting from using just bodyweight or light weights. Progressive overload is often regarded as essential to maintain hypertrophy over a long period of time. As using MMC makes the movement of lifting a weight more challenging, this leads to lowering the weight or reps being performed each set. This can therefore mean that towards the end of a set, the focus on MMC may start to diminish as the priority shifts becomes getting the last few reps out.  Advanced lifters who are able to consistently apply the same amount of focus on each rep or every set may find that they are able to execute MMC effectively without compromising the quality of the reps, however this may take a lot of practice and time. It certainly isn’t as easy as it sounds but it is most definitely worth the effort once you get the hang of it!

Everybody is different and some people may find they are entirely able to remain focussed on MMC. It may just be a case of trial and error to see what works most effectively for you. If you are an intermediate lifter and find you are making solid progress without MMC, try to incorporate it into some exercises as discussed below and see how it works for you!

The Take Home:

The benefits of MMC are only applicable to strength training where increased activation and muscle growth are the goal (7,8). If your goal is to increase your power with olympic lifting/crossfit style training (think explosive exercises such as the barbell snatch), you should focus more on your technique and performing the exercise correctly with good form, rather than how the exercise feels on specific muscles (4, 6).We recommend implementing the 5 MMC strategies discussed, at the beginning of your training session on one or two exercises. This is because it can sometimes feel mentally draining when first attempting MMC, but don’t be deterred as it will become easier each time you do it. Therefore, the more you practice MMC, the easier it will become. Gradually integrate MMC techniques with several exercises and then build on that with time until MMC becomes a part of every set and rep you perform. 

If gaining muscle mass is your goal, the mind-muscle connection can be a huge factor is helping you achieve your personal fitness success. So, follow our tips and give it a go to see the benefits for yourself!
