NASM Certified Personal Trainer: 10 sample questions

Practice questionReviewedExercise Technique and Training Instruction › Resistance and Cardio Technique★★★★★

Question 1. A squat uses a 4/2/1 tempo. What does this mean?

  1. ① 4 seconds lifting, 2 seconds pause, 1 second lowering
  2. ② 4 seconds pause, 2 seconds lowering, 1 second lifting
  3. ③ 4 seconds lowering, 2 seconds pause, 1 second lifting
  4. ④ 4 sets, 2 minutes rest, 1 exercise
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ 4 seconds lowering, 2 seconds pause, 1 second lifting

Key point: Tempo order: lowering / pause / lifting

Tempo is written as lowering (eccentric), pause (isometric), then lifting (concentric). A 4/2/1 tempo is slow and controlled.

Wrong choices

  • 4 seconds lifting, 2 seconds pause, 1 second lowering: The numbers list lowering first, then the pause, then lifting.
  • 4 seconds pause, 2 seconds lowering, 1 second lifting: The first number is for lowering, not the pause.
  • 4 sets, 2 minutes rest, 1 exercise: Tempo describes speed of one rep, not sets or rest.
Practice questionReviewedProgram Design › The OPT Model and Its Phases★★★★★

Question 2. How many phases are in the NASM OPT model?

  1. ① Three
  2. ② Four
  3. ③ Six
  4. ④ Five
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ Five

Key point: OPT model: 5 phases in 3 levels

The OPT model has five phases: Stabilization Endurance, Strength Endurance, Muscular Development, Maximal Strength, and Power. They are grouped into three levels: stabilization, strength, and power.

Wrong choices

  • Three: There are three levels, but five phases.
  • Four: The model has one more phase than this.
  • Six: The model has one fewer phase than this.
Practice questionReviewedAssessment › Movement and Posture Assessment★★★★★

Question 3. What is the main purpose of the overhead squat assessment?

  1. ① To test maximal leg strength
  2. ② To find movement compensations in the body
  3. ③ To measure resting heart rate
  4. ④ To measure body fat
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ② To find movement compensations in the body

Key point: Overhead squat finds movement compensations

The overhead squat assessment shows how the body moves as a whole. A trainer uses it to spot compensations and plan corrective work.

Wrong choices

  • To test maximal leg strength: It does not measure maximum strength.
  • To measure resting heart rate: It does not measure heart rate.
  • To measure body fat: It does not measure body fat.

Question 4. A muscle produces force while it lengthens. Which type of contraction is this?

  1. ① Eccentric
  2. ② Concentric
  3. ③ Isometric
  4. ④ Isokinetic
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ① Eccentric

Key point: Eccentric = muscle lengthens under tension

Lowering a weight slowly is an eccentric contraction. The muscle makes force as it gets longer.

Wrong choices

  • Concentric: In a concentric contraction the muscle shortens.
  • Isometric: In an isometric contraction the muscle stays the same length.
  • Isokinetic: This is constant speed movement.

Question 5. In a SMART goal, what does the letter T stand for?

  1. ① Total
  2. ② Trainer-approved
  3. ③ Time-bound
  4. ④ Tough
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ Time-bound

Key point: SMART: T = time-bound

SMART goals are specific, measurable, attainable, realistic, and time-bound.

Wrong choices

  • Total: This is not part of SMART.
  • Trainer-approved: This is not part of SMART.
  • Tough: This is not part of SMART.

  2. ② Prescribing medication
  3. ③ Treating a medical condition
  4. ④ Designing an exercise program for a healthy client
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ Designing an exercise program for a healthy client

Key point: CPT designs exercise programs, not medical care

A trainer designs and teaches exercise. Diagnosing, prescribing, and treating are for licensed healthcare professionals.

Wrong choices

  • Diagnosing an injury: Diagnosis is for medical professionals.
  • Prescribing medication: Prescribing drugs is outside a trainer's scope.
  • Treating a medical condition: Treatment is for medical professionals.
Practice questionReviewedExercise Technique and Training Instruction › Resistance and Cardio Technique★★★★★

Question 7. A client cannot do a full push-up with good form. Which change is the best regression?

  1. ① Push-up with feet on a stability ball
  2. ② Add a weighted vest
  3. ③ Incline push-up with hands on a bench
  4. ④ Clap push-up
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ Incline push-up with hands on a bench

Key point: Easier push-up = raise the hands (incline)

Putting the hands on a bench takes weight off the arms and chest. This makes the push-up easier while the client keeps good form.

Wrong choices

  • Push-up with feet on a stability ball: This is harder, not easier.
  • Add a weighted vest: This is harder.
  • Clap push-up: This is a power exercise and is much harder.
Practice questionReviewedProgram Design › The OPT Model and Its Phases★★★★★

  1. ① Strength Endurance
  2. ② Muscular Development
  3. ③ Stabilization Endurance
  4. ④ Maximal Strength
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ Stabilization Endurance

Key point: OPT Phase 1 = Stabilization Endurance

Phase 1 is Stabilization Endurance. It builds control, balance, and muscle endurance and is the starting point for most beginners.

Wrong choices

  • Strength Endurance: This is Phase 2.
  • Muscular Development: This is Phase 3.
  • Maximal Strength: This is Phase 4.

▼ Show answer and explanation▲ Hide answer and explanation

Answer: ① Upper crossed syndrome

Wrong choices

  • Lower crossed syndrome: This pattern involves the hips and low back.
  • Pronation distortion syndrome: This pattern involves the feet and knees.
  • Scoliosis: This is a side-to-side curve of the spine, not this pattern.
