Exercise physiologists design physical activity programs that help people improve their fitness, often as part of treatment for heart disease, diabetes and other chronic conditions. Wearables and apps now track heart rate and activity, and AI can summarize that data. Testing patients, adjusting programs safely and keeping people motivated stay with the physiologist.
The short answer: AI is not set to replace this clinical work, and demand is rising. The ILO's 2025 index rates health professionals not elsewhere classified, the closest group, as not exposed, with a score of 0.20. The US Bureau of Labor Statistics projects 13 percent growth for exercise physiologists from 2025 to 2035, much faster than average, with about 1,400 openings a year. Projections are estimates, not guarantees.
How exposed exercise physiologists are
The International Labour Organization scores occupations' tasks from 0 (cannot be automated with generative AI) to 1 (could be done without a human operator), and groups them into gradients from 1 to 4, with 4 the most exposed; below them sit minimal exposure and not exposed (ILO Working Paper 140, 2025).
| Occupation (ISCO-08) | ILO category | Mean task score (0 to 1) |
|---|---|---|
| Health Professionals Not Elsewhere Classified | Not exposed | 0.20 |
The ILO scores groups of occupations, so this is the closest group for exercise physiologists, not a score for the job title itself.
What the BLS projects
| Occupation | Projected change 2025 to 2035 | Openings a year |
|---|---|---|
| Exercise physiologists | Grow 13% | About 1,400 |
The BLS says that as chronic conditions become more common, more exercise physiologists will be needed to help patients manage symptoms through personalized exercise programs, with growth expected in hospitals and ambulatory care. Its outlook does not mention AI.
Where AI is helping
- Summarizing data from wearables and fitness tests.
- Drafting exercise plans for review.
- Writing session notes and progress reports.
What stays with exercise physiologists
- Testing: stress tests and fitness assessments with the patient present.
- Safety: adjusting exercise to a patient's condition and medication.
- Motivation: keeping patients with a program over months.
- Checking AI help: generated plans and summaries can be wrong, which NIST calls confabulation (NIST AI 600-1). See checking AI output.
How the job is changing
More patient data arrives from wearables, which makes interpreting it part of the job, while testing and supervising exercise stay hands-on. This page is general information, not career advice.

Pay and how to get in
The US Bureau of Labor Statistics puts the median annual pay for exercise physiologists at $59,460 in May 2025, against $50,980 for all workers. The typical education needed to enter is: bachelor's degree. See how this job compares in AI exposure by pay and AI exposure by education level.
Questions and answers
Will AI replace exercise physiologists?
Unlikely in the near term. The closest ILO group is not exposed, and the BLS projects 13 percent growth from 2025 to 2035.
Why is demand for exercise physiologists growing?
The BLS links it to the growing prevalence of chronic conditions and rehabilitation work in hospitals and ambulatory care.
How many openings are expected?
About 1,400 a year on average over the decade, according to the BLS.
Can a fitness app replace an exercise physiologist?
Apps track activity, but clinical testing and safe programs for people with chronic conditions need a trained professional.
