CORRECT DETAILED ANSWERS AND IN-DEPTH RATIONALES
(BASED ON THE 7TH EDITION OPT MODEL) UPDATED 2026
GUARANTEED PASS A+
About this resource:
Let’s be honest—the NASM-CPT exam is tough. It’s not just about memorizing muscle origins; it’s
about applying complex concepts under a ticking clock. If you’re here, you’re probably tired of reading
the same dense textbook chapters and ready to actually test your knowledge.
That’s exactly why I created this document.
Here are 200+ practice questions designed to feel just like the real thing. I’ve formatted the answers
with bold/italicized text so you can grade yourself instantly, and included italicized rationales for
every single choice—not just the right one. Trust me, reading the rationales is where the magic
happens; it’s how you learn to think like NASM.
SECTION 1: BASIC AND APPLIED SCIENCES (Questions 1–66)
1. The human skeleton consists of approximately how many bones?
A) 126
B) 206
C) 306
D) 406
B) 206 — The adult human skeleton consists of approximately 206 bones. The axial skeleton (skull,
vertebral column, rib cage) contains 80 bones, and the appendicular skeleton (limbs and girdles)
contains 126 bones.
2. Which type of muscle tissue is under voluntary control?
A) Cardiac muscle
B) Smooth muscle
C) Skeletal muscle
D) Both A and B
,C) Skeletal muscle — Skeletal muscle is the only muscle tissue under voluntary control. Cardiac and
smooth muscles are involuntary.
3. Which of the following is a prime mover (agonist) during a biceps curl?
A) Triceps brachii
B) Biceps brachii
C) Deltoid
D) Brachialis
B) Biceps brachii — The biceps brachii is the prime mover (agonist) during a biceps curl. The triceps
brachii is the antagonist.
4. Which type of joint is the shoulder?
A) Hinge joint
B) Pivot joint
C) Ball-and-socket joint
D) Saddle joint
C) Ball-and-socket joint — The shoulder and hip are ball-and-socket joints, allowing movement in
multiple planes (flexion, extension, abduction, adduction, rotation).
5. What is the functional unit of the nervous system?
A) Axon
B) Dendrite
C) Neuron
D) Synapse
C) Neuron — The neuron is the functional unit of the nervous system, responsible for transmitting
nerve impulses.
6. Which energy system produces ATP most rapidly?
A) Oxidative system
B) Glycolytic system
, C) ATP-PC system
D) Beta-oxidation
C) ATP-PC system — The ATP-PC (phosphocreatine) system produces ATP most rapidly, lasting
approximately 10–15 seconds of maximal effort.
7. Which of the following is the innermost layer of muscular connective tissue?
A) Epimysium
B) Perimysium
C) Endomysium
D) Fascia
C) Endomysium — The endomysium is the innermost layer of connective tissue that surrounds
individual muscle fibers.
8. Which plane divides the body into left and right halves?
A) Frontal plane
B) Transverse plane
C) Sagittal plane
D) Horizontal plane
C) Sagittal plane — The sagittal plane divides the body into left and right halves. The frontal plane
divides anterior/posterior, and the transverse plane divides superior/inferior.
9. Which of the following is an example of a first-class lever?
A) Biceps curl
B) Plantar flexion
C) Neck extension
D) Knee extension
C) Neck extension — Neck extension is a first-class lever, where the fulcrum (atlanto-occipital joint) lies
between the effort (muscle) and the load (head).
10. What is the primary function of the Golgi tendon organ?
, A) Detect muscle length changes
B) Detect muscle tension
C) Detect joint position
D) Detect pain
B) Detect muscle tension — The Golgi tendon organ (GTO) detects tension within the muscle-tendon
complex and can cause autogenic inhibition (relaxation) when tension is high.
11. Which of the following muscles is primarily responsible for shoulder abduction?
A) Pectoralis major
B) Latissimus dorsi
C) Deltoid
D) Teres major
C) Deltoid — The deltoid (particularly the middle fibers) is the primary muscle responsible for shoulder
abduction.
12. The exchange of gases occurs in which structures of the lungs?
A) Bronchi
B) Bronchioles
C) Alveoli
D) Trachea
C) Alveoli — Alveoli are the tiny air sacs in the lungs where gas exchange (oxygen and carbon dioxide)
occurs between the air and blood.
13. Which of the following best defines the term "autogenic inhibition"?
A) Contraction of a muscle in response to stretch
B) Inhibition of a muscle in response to high tension
C) Reciprocal inhibition of the antagonist
D) Activation of muscle spindles
