General definitions you need to memorize

  • Muscular imbalances: The alteration of a muscles length that surrounds a joint.
  • How muscular imbalances are caused: Muscular imbalances are caused by a variety of different things including emotional duress, repetitive movements, bad training techniques, the lack of neuromuscular efficiency, poor core strength, cumulative trauma and stress caused by postural problems.
  • The differences between obesity and overweight: Being overweight is considered having a BMI index between the ranges of 25 and 29.9 and between 25 and 30 pounds over the recommended height to weight ratio. Being obese is considered having a BMI of 30 or more with at least 30 pounds overweight for the height to weight ratio.
  • Proprioception: Proprioception is the cumulative input into the central nervous system coming from the various Mechanoreceptors in the body that sense limb movement as well as body position. For example, while running your feet send proprioceptive feedback depending on the type of surface you are running on.
  • Proprioceptively enriched environments: These are unstable environments that are controlled. These challenge one’s Internal balance and stabilization.
  • The OPT training model: There will be a lot more chapters talking about the OPT training model. For now, all you should know is that it is a systematic training approach that builds on itself and the general phases of stabilization, strength, and power.

  1. this is a great study guide but how do I know what answers I got right/wrong on the practice tests?

    1. Hey Dana,
      Currently on my website I do not have the answers available for the free practice tests. That is a good recommendation and I will look into putting up a cheat sheet that contain all of the answers on my website somewhere.

  2. What’s the difference between strength and power? If I’m understanding properly, phase 1 is stability, 2-4 is strength, and 5 is power. I’m not sure I understand the difference between the two.

    1. Hello Stuart,
      Strength has to do with maximal overall strength were power has to do with not only how strong you are but how fast you can move the weight that you are lifting. This is very important for being explosive and for athletic training

  3. I want to pass this test so bad but i am overwhelmed by the studying it takes to pass this. My test is on July 18. I know we have to study hard but i want to study smart and need some pointers and the best way to retain the information, learn the concepts and how to apply them so i can pass this dang thing. I know i can make a hell of trainer but the first step is getting certified. I am willing to do what it takes.

  4. I was wondering if the free study guide, practice test & flashcards was a lighter version of the paid $99 version.

    1. Hey Steve, This free study guide is much different than the paid study guide and study materials I used to sell on my website. Is this what you are referring to? If this is what you are referring to, they are significantly different.

  5. is this all I have to study to pass I have bought the self study program from nasm but its just an ebook and quizzes and summarize how do I study the self study program ?

    1. Hey Mark, this study guide for NASM is a good place to start. That being said, there are much better study guides and study materials out there that you can utilize. I recommend checking out Trainer Academy as they have helped hundreds of my students passed the national Academy of sports medicine exam.

    1. Hey Kevin,
      My free study materials will definitely help you pass the national Academy of sports medicine final exam. That being said, it is not the best study materials out there it is just a good place to start.
