What is ACE certification?
ACE was founded in 1985 with a mission to get people moving safely and effectively. It is accredited by the NCCA — the gold standard in fitness certification accreditation — meaning it meets the highest industry standards for exam development and delivery.
ACE’s approach is built around behaviour change science and client-centred coaching. Unlike NASM which focuses heavily on corrective exercise and movement science, ACE emphasises helping clients develop sustainable healthy habits for life. This makes ACE particularly well suited for trainers who want to work with general population clients, corporate wellness programmes, and health coaching roles.
ACE has certified over 90,000 fitness professionals and is recognised by employers in more than 90 countries worldwide.
How much does ACE certification cost?
| Package | Cost | What's included |
|---|---|---|
| Basic | $675 | Exam + digital study materials |
| Standard | $799 | Exam + textbook + practice tests |
| Premium | $975 | Everything + live coaching sessions |
| Payment plan | From $38/month | 0% interest financing available |
| Recertification | $129 every 2 years | 20 CECs required |
ACE’s top package at $975 is significantly more affordable than NASM‘s premium package at $1,999 — making ACE better value at the higher end. The $38/month payment plan makes it one of the most accessible certifications for budget-conscious students.

How hard is the ACE CPT exam?
The ACE CPT exam is widely considered the most challenging of the major personal trainer certifications:
- Number of questions: 150 multiple choice
- Time allowed: 3 hours
- Pass rate: approximately 65%
- Exam format: Closed book
- Retake policy: 3 attempts maximum, 60-day waiting period
The 65% pass rate means roughly 1 in 3 students fail on their first attempt. This is significantly lower than NASM (85%) and ISSA (90%). Students consistently report that ACE requires thorough deep study — surface-level revision is not enough.
How long does ACE take to complete?
- Minimum completion: 8–10 weeks with intensive study
- Average completion: 3–6 months at 1–2 hours per day
- Maximum time allowed: 1 year from enrollment
Most students who pass on their first attempt report studying for a minimum of 3 months. Given the 65% pass rate, rushing through ACE is not recommended.
What do you learn in the ACE CPT program?
The ACE curriculum is built around four integrated training domains:
Domain 1 — Client interviews and assessments Health history screening, postural assessment, fitness testing, goal setting, and identifying when to refer clients to medical professionals.This knowledge helps justify premium personal trainer salary rates
Domain 2 — Programme design and implementation Training principles, exercise selection, programme periodisation, resistance training, cardiovascular training, and flexibility programming.
Domain 3 — Progression and modification Monitoring client progress, adapting programmes, working with special populations including seniors, pregnant clients, and those with chronic conditions.
Domain 4 — Professional conduct and business practices Scope of practice, legal considerations, client communication, and basic business skills for personal trainers.“You can pursue all of this without a degree”
Which gyms accept ACE certification?
ACE is widely accepted across the fitness industry globally:
- Equinox
- Gold’s Gym
- LA Fitness
- Anytime Fitness
- Planet Fitness
- Crunch Fitness
- 24 Hour Fitness
- YMCA
- Corporate wellness centres
- Hospital-based fitness programmes
ACE’s recognition in 90+ countries gives it broader international acceptance than NASM’s 45-country reach.
Among personal trainers who hold ACE certification, the most consistent theme is long-term career value over short-term ease. Trainers frequently describe the ACE exam as the hardest thing they studied for — but also the credential that gave them the most confidence walking into their first gym interview. Hiring managers at corporate wellness programmes and premium health clubs consistently cite ACE as a trusted, immediately recognisable credential. Several certified trainers report that ACE's behaviour change curriculum gave them a genuine edge with general population clients — particularly those dealing with weight management, stress, and lifestyle conditions — where motivation and habit coaching matter more than corrective exercise knowledge. The most common criticism centres on the lack of a business and nutrition module in the base certification, with many ACE graduates spending an additional $300–$500 on nutrition specialisations after completing the CPT. Despite this, the majority of surveyed ACE-certified trainers say they would choose the same certification again — citing employer trust, curriculum depth, and the sense of credibility that comes with passing one of the industry's most rigorous exams as their primary reasons.

Based on this comparison — ACE is the best choice for health coaching and corporate wellness roles, where its behaviour change curriculum gives it a genuine edge. NASM wins for gym employment — its employer recognition and 85% pass rate make it the safest first certification for those targeting commercial fitness facilities. ISSA is the best overall value — the only certification that includes nutrition, business training, and a job guarantee in its base package, with the highest pass rate and most flexible exam format. If you can only pick one, match your choice to where you plan to work — not just the price tag.
Working full time? Choose ISSA — the open book at-home exam and 2-year deadline fits around a busy schedule with no pressure to book a testing centre slot.
Targeting a specific gym chain? Check their job listings first — most major chains list their preferred certifications. NASM and ACE appear most frequently in premium facility listings.
On a tight budget? ISSA frequently runs 40–60% off sales — the base CPT can drop to as low as $299. Set a price alert and enroll during a promotion.
Want to go independent quickly? ISSA's built-in business and nutrition modules save you $300–$500 in additional certifications — making it significantly cheaper for the full skill set.
