About this test
This free NASM practice test has 15 questions written by the StudyPDF team for people preparing for the NASM Certified Personal Trainer exam. Answer all 15, then check your score and read the explanation for every question. They follow the six domains in NASM's published exam outline: exercise science and nutrition basics, behavioral coaching, assessment, program design, exercise technique and professional responsibility. They are original practice questions, not NASM questions.

1.A client performs a biceps curl, moving the forearm toward the shoulder. In which plane of motion does most of that movement happen?
- A. The frontal plane
- B. The sagittal plane
- C. The transverse plane
- D. The oblique plane
Answer: B. The sagittal plane
The sagittal plane splits the body into left and right halves, and flexion and extension happen in it: curls, squats, lunges and walking. The frontal plane splits front from back and holds abduction and adduction, like a lateral raise. The transverse plane splits top from bottom and holds rotation. There is no oblique plane in the standard three.
2.While lowering into a squat, the quadriceps lengthen while still producing force to control the descent. What is this muscle action called?
- A. Isometric
- B. Concentric
- C. Eccentric
- D. Reciprocal
Answer: C. Eccentric
An eccentric action produces force while the muscle lengthens, which is how it brakes a load. A concentric action produces force while the muscle shortens, such as standing back up. An isometric action produces force with no change in muscle length. Reciprocal describes reciprocal inhibition, which is a reflex and not a muscle action.
3.Complete the sentence.
Around a joint, the muscle acting as the prime mover is the _____, and the muscle on the opposite side that opposes it is the _____.
Options for blank 1: agonist, antagonist, synergist, stabilizer
Options for blank 2: agonist, antagonist, synergist, stabilizer
Answer: agonist, antagonist
The agonist is the prime mover and the antagonist is the muscle on the opposite side of the joint that lengthens or relaxes to let the movement happen. A synergist assists the prime mover, and a stabilizer holds a joint steady so the movement can happen at all. During the up phase of a biceps curl, the biceps is the agonist and the triceps is the antagonist.
4.Which energy system supplies most of the ATP for an all-out effort lasting about 10 seconds, such as one maximal sprint?
- A. The ATP-PC system
- B. The glycolytic system
- C. The oxidative system
- D. Protein metabolism
Answer: A. The ATP-PC system
The ATP-PC system uses stored ATP and creatine phosphate, so it is the fastest to respond but runs low in roughly ten seconds. The glycolytic system takes over for hard efforts that last from about ten seconds to a couple of minutes. The oxidative system carries longer, lower intensity work, and the three systems always overlap instead of switching on one at a time.
5.A client says they are seriously thinking about starting an exercise routine sometime in the next six months, but they have made no plans yet. Which stage of change is this?
- A. Precontemplation
- B. Contemplation
- C. Preparation
- D. Maintenance
Answer: B. Contemplation
In the Transtheoretical Model, precontemplation means no intention to change in the next six months, contemplation means intending to change in that window without a plan, and preparation means getting ready to act soon, usually with small steps already taken. Then come action and maintenance. Matching your coaching to the stage matters: a contemplator needs help weighing pros and cons, not a 12 week program.
6.Which of the following fall outside a personal trainer's scope of practice?
Select all that apply.
- A. Diagnosing the cause of a client's shoulder pain
- B. Writing a detailed meal plan to treat a medical condition
- C. Providing psychological counseling for an eating disorder
- D. Teaching a client how to perform a goblet squat safely
- E. Sharing general, publicly available information about macronutrients
Answer: A. Diagnosing the cause of a client's shoulder pain, B. Writing a detailed meal plan to treat a medical condition, C. Providing psychological counseling for an eating disorder
NASM's published outline lists diagnosing injury, meal planning and psychological counseling as limits of a personal trainer's scope. The right move is to refer the client to a physician, a registered dietitian or a mental health professional. Teaching technique is the core of the job, and general nutrition education is usually fine, though what you may say about food depends on your credential and local rules.
7.A new client's PAR-Q answers show a physician has told them they have a heart condition. What should the trainer do before assessing or training them?
- A. Start with light cardio only and watch closely
- B. Have the client sign a waiver and proceed as planned
- C. Cut every assessment to half intensity
- D. Ask for clearance from the client's physician first
Answer: D. Ask for clearance from the client's physician first
A yes answer on the PAR-Q for a known condition is a signal to get medical clearance before any assessment or program. A waiver protects the business, not the client, and lowering the intensity does not remove the need for the physician's input. Once the client is cleared, the physician's limits become part of the program.
8.Complete the sentence.
The Rockport Walk Test uses the time taken to walk one mile and the heart rate at the end to estimate _____.
Options for blank 1: VO2 max, one-repetition maximum, body fat percentage, joint flexibility
Answer: VO2 max
The Rockport test is a submaximal cardiorespiratory assessment: the client walks one mile as fast as they can and the trainer records the finishing heart rate and time, which feed an estimate of VO2 max. It suits clients who should not run. A one-repetition maximum tests strength, and skinfold calipers estimate body composition.
9.Which list gives the three levels of the OPT model in the correct order?
- A. Stabilization, power, strength
- B. Strength, stabilization, power
- C. Stabilization, strength, power
- D. Power, strength, stabilization
Answer: C. Stabilization, strength, power
The OPT model starts with stabilization, builds to strength and finishes with power. It breaks into five phases: stabilization endurance, strength endurance, hypertrophy, maximal strength and power. Clients who move poorly or are new to training start in stabilization, because control and joint support come before heavy loading or explosive work.
10.Which of the following are flexibility training methods?
Select all that apply.
- A. Self-myofascial release
- B. Static stretching
- C. Dynamic stretching
- D. Plyometric jumping
- E. Superset training
Answer: A. Self-myofascial release, B. Static stretching, C. Dynamic stretching
Self-myofascial release, static stretching and dynamic stretching are all flexibility methods, along with active-isolated stretching. Plyometric jumping is reactive training, which builds the ability to produce force quickly. A superset is a resistance training system that pairs two exercises back to back.
11.A client trains hard six days a week with no recovery, and now has constant fatigue, poor sleep and lifts that keep dropping. Which stage of the general adaptation syndrome does this describe?
- A. Exhaustion
- B. Alarm
- C. Resistance development
- D. Adaptation to stress
Answer: A. Exhaustion
The general adaptation syndrome has three stages: alarm, when the body first meets a stressor, resistance development, when it adapts and gets stronger, and exhaustion, when the stress outlasts the body's ability to recover. This client has hit exhaustion, which is an overtraining pattern. The fix is more rest and a lower load, not more volume. The phrase adaptation to stress is not a stage.
12.Complete the sentence.
One gram of carbohydrate provides about _____ kilocalories, and one gram of fat provides about _____.
Options for blank 1: 2, 4, 7, 9
Options for blank 2: 2, 4, 7, 9
Answer: 4, 9
Carbohydrate and protein each provide about 4 kilocalories per gram and fat provides about 9, which is why fat is the most energy dense macronutrient. Alcohol, which is not a nutrient, provides about 7. These are the standard values used for energy calculations on exams and food labels.
13.A trainer rests a hand lightly on a client's glutes during a bridge to cue the muscle that should be working. Which cueing technique is this?
- A. Visual
- B. Auditory
- C. Tactile
- D. Reactive
Answer: C. Tactile
Touch is a tactile cue, sometimes called a kinesthetic cue, and it works well for muscles the client cannot easily feel. Visual cueing means demonstrating the movement or using a mirror. Auditory cueing means describing it in words. A good session mixes all three, and a touch cue should always be agreed with the client first. Reactive is a type of training, not a cue.
14.A client collapses during a session and does not respond. What is the right response under a facility's emergency action plan?
- A. Wait a few minutes to see whether the client recovers on their own
- B. Give the client water and have them sit up
- C. Call the client's emergency contact before anything else
- D. Activate EMS, follow the facility emergency action plan and send for the AED
Answer: D. Activate EMS, follow the facility emergency action plan and send for the AED
NASM's outline expects a trainer to know the emergency protocols: activate EMS and put the facility's emergency action plan into motion, which includes getting the AED and starting CPR if it is needed and you are trained. Waiting, water and phone calls to family all cost time. This is why current CPR and AED certification is a requirement for the credential. This is exam practice, not medical guidance.
15.Which of the following are good reasons to reassess a client?
Select all that apply.
- A. The client's progress has plateaued
- B. The client's goal changes from general fitness to a half marathon
- C. The client buys new running shoes
- D. The client has a new health diagnosis
- E. The trainer switches the gym playlist
Answer: A. The client's progress has plateaued, B. The client's goal changes from general fitness to a half marathon, D. The client has a new health diagnosis
Reassessment is triggered by changes that affect the program: a plateau, a new goal, a change in health, a change of training phase or enough time passing. New shoes and a new playlist change neither the client's needs nor their results. Reassessing at the right moments is how a trainer keeps a program matched to the client instead of to the calendar.
What the NASM CPT exam covers and what this practice test checks
NASM's candidate handbook describes the Certified Personal Trainer exam as 120 questions, of which 100 are scored and 20 are unscored pretest items, with a two hour time limit and a scaled passing score of 70. The handbook also gives the weight of each of the six domains: Basic and Applied Sciences and Nutritional Concepts 15 percent, Client Relations and Behavioral Coaching 15 percent, Assessment 16 percent, Program Design 20 percent, Exercise Technique and Training Instruction 24 percent, and Professional Development and Responsibility 10 percent. NASM can change any of this, so confirm the current numbers on nasm.org before you plan around them.
Those weights tell you where the points are. Exercise technique and program design together are 44 percent of the exam, which is more than the sciences and the behavioral domain combined. It is easy to spend most of your time on anatomy and energy systems because that part feels like school, then meet an exam that leans on what a trainer should do for the client in front of them.
This sampler is 15 questions, so it cannot copy those weights. It gives breadth instead: five questions on sciences and energy, one on behavioral coaching, three on assessment, three on program design, one on exercise technique and two on professional responsibility. Use it to find out which domain you have not studied yet, then study that domain with your own course materials.
It is also a practice test for the knowledge, not a shortcut to the exam. The questions are original, written to NASM's published outline, and nothing here is taken from the exam, from NASM's textbook or from a prep provider's question bank.
How to use this NASM practice test and study the OPT model
Take the test once, in one sitting, without notes. When you finish, every question shows the correct answer and an explanation. Read all of them, including the ones you got right, because a right answer reached by a guess teaches you nothing.
Then sort every miss into one of the six domains. Three misses in assessment mean you should rework the assessments, not reread everything. A miss on the general adaptation syndrome and a miss on rest and recovery are the same topic seen twice, so study them together.
Give the OPT model its own session. NASM's outline lists three levels, stabilization, strength and power, and five phases, stabilization endurance, strength endurance, hypertrophy, maximal strength and power. Know the order, know what each level is for, and practice explaining why a client who moves poorly in an assessment starts in stabilization rather than in strength.
Expect questions that put a client in front of you, so practice reading a question for what the client has told you, then choosing the safest action that is inside a trainer's scope. When two answers both sound reasonable, the one that stays in scope and refers out when needed is usually the better one.
This page is exam practice, not medical, injury or nutrition guidance. A real client with a health condition needs clearance from their own doctor, and what a trainer may say about food depends on your credential and where you work.
How StudyPDF builds full practice tests from your own materials
Fifteen questions can show you where you are shaky. They cannot get you ready on their own, and no generic bank matches the textbook, course or study guide you are actually working through.
StudyPDF works from your material instead. You upload your own NASM course notes, lecture slides or textbook chapters, and Bo, the study agent, builds full-length practice tests from those exact pages. Every question is grounded in your material, and every explanation cites where the answer comes from. You can regenerate fresh tests whenever you want, narrow them to one domain such as program design, and track which concepts you keep missing.
You do not have to upload anything to start. If you have no file at hand, name a topic instead, for example the OPT model phases or the stages of change, and Bo writes a practice test from that. Starting is free.
