These 10 free ACSM-GEI questions are organized by exam domain, so you can see how each part of the Certified Group Exercise Instructor blueprint is tested. Reveal the answer and explanation under each question.
A room-booking delay shortens a vigorous cycling class, and the next class must start on time. The planned workout includes a progressive warm-up, several hard intervals, and an active cool-down. Which revision best preserves physiological preparation and recovery?
Correct answer: A - Remove the final hard interval and retain the warm-up and active cool-down.
An aquatic class uses hand paddles with adjustable openings. Participants keep the paddles fully submerged and move them through the same arc at the same speed. Which setup creates the greatest resistance against the direction of travel?
Correct answer: D - Openings closed, with the broad face leading through the water.
The upper-body portion of a general-conditioning circuit contains chest presses, overhead presses, and triceps extensions. One station can be added. Which exercise most directly corrects the imbalance in movement patterns?
Correct answer: C - Seated resistance-band rows.
An adult who does not yet exercise regularly says, "I have booked beginner classes for next Monday and Thursday and arranged childcare. I want those two sessions to become my weekly routine." Using that twice-weekly routine as the target behavior, identify the stage of change and the appropriate emphasis.
Correct answer: D - Preparation; make the first week's attendance plan specific and achievable.
A participant tries slow-lowering lunges for the first time. The next morning, both thighs feel mildly tender; the discomfort is more noticeable 36 hours after class. There was no sudden pain during exercise, and there is no focal swelling, bruising, or loss of normal function. Which explanation best fits this pattern?
Correct answer: A - Delayed-onset muscle soreness following an unfamiliar eccentric exercise stimulus.
"I understand what to do, but I don't believe I can finish," says a newcomer before a resistance circuit. The instructor chooses to build self-efficacy through a mastery experience. Which approach uses that mechanism?
Correct answer: A - Have the participant complete an achievable version of one station successfully.
During bodyweight squats, a participant's knees move forward beyond the toes. The heels remain down, the knees track in the same direction as the feet, and the trunk stays controlled. The movement is pain-free. A substitute instructor suggests correcting the forward knee travel. What is the most defensible response?
Correct answer: C - Allow the current pattern; forward knee travel alone does not require correction.
An asymptomatic participant has a measured maximal heart rate of 180 beats/min and a resting heart rate of 60 beats/min. During steady cycling, the heart rate is 102 beats/min. No medication affects the heart-rate response. The session targets moderate intensity using heart-rate reserve, not percentage of maximal heart rate. Which interpretation and coaching response are appropriate?
Correct answer: B - 35% of heart-rate reserve; gradually increase the workload toward moderate effort.
A dance class can perform two movement patterns accurately on their own, but participants consistently enter the second pattern late. The instructor's directions are audible and correct, yet the new movement is named on its first beat. To fix the transition, the instructor should:
Correct answer: B - Preview the next movement before the current phrase ends, then demonstrate it as the new phrase begins.
The next resistance station uses chest presses while lying flat on the back for several minutes. A regular participant is 24 weeks pregnant, feels well, and has obstetric approval to continue moderate resistance exercise. How should the instructor adapt this station?
Correct answer: B - Use a standing band chest press with stable footing and a suitable resistance.
