Should You Use Manual Muscle Testing?

ManualMuscleTestManual muscle testing (MMT) can be a valuable tool in your assessment arsenal.

Now I know what the naysayers are going to say:

It’s not reliable enough.

It’s hard to use between testers.

And trust me, I agree with those sentiments. Like virtually any test in isolation, manual muscle testing is not perfect.

But as a strength coach or personal trainer, I feel there is some value in manual muscle testing.

One of the biggest issues you’re going to see when you starting coaching clients and athletes is that they all love to compensate.

But how are they going to cheat?

Manual muscle testing not only tells us if specific muscles have sufficient strength, but they also give us clues as to how a client will cheat or compensate.

Here’s a quick video to demonstrate all this:

Take a standard exercise like a chest supported row – it can’t get much simpler than that, right?

Lay on your stomach, grab the handles, and row away. It’s just that simple!

Until you actually watch people perform the exercise, that is.

I always tell my interns and coaches that we have to make sure we’re training the muscle or joint we’re trying to train.

It sounds simple, but it’s important.

If your goal is to teach someone to row, you’re trying to hit those mid-back muscles like the rhomboids, middle traps, lower traps, etc.

But we know that most people are horribly weak in this area.

Couple that with the need/desire to use more weight, and you have a recipe for compensation.

When clients are rowing, it’s very common to see any (or all) of the below compensations:

  • Hyperextension of the lumbar spine.
  • Anterior humeral glide/excessive shoulder extension.
  • Protrusion of the head and neck.

Now that you have an idea of how you can use MMT to determine cheats and compensations, here’s another quick video on how to row effectively.

I hope this gives you an idea as to why we use MMT in our assessments. Quite simply, it’s not just an assessment of strength and/or joint stability.

  1. Hey Mike,

    If you do the installment option for Dx Fitness, when does the second installment hit your credit card?

  2. Great content. Easy to see compensations this way, gonna have to talk to some PTs and work on some skills. Probably see the compensation on a hip flexor test? Also we tell our folks to pull the wrist from eyes to the hip and squeeze a sponge with the armpit. Are we cueing them into anterior glide at the shoulder, haven’t noticed it but wondering what you thought.

  3. Hey Mike,

    This technique has helped me in most of my back workouts. As a prior Marine, you can only imagine how many pull-ups I have done…fitness test, after fitness test, or training session after training session.

    Anyways, it was only for the number, and the endurance aspect, of scoring 100 points on a physical fitness test.

    Now, after watching a few of your videos, being part of elite mentorship training, and becoming a personal trainer, when I do a full pullup, I feel it in muscles I never knew existed.

    I also, have my clients do a lot lighter weight, and they even feel it in the muscles in the back! Great stuff, and I really enjoy learning from your coaching cues.

    Thanks again!

    George
