Measured use over time
Of the Claude.ai conversations Anthropic sampled and tied to a work task, 0.053% went to this job's tasks in May 2026, the 227th largest of the 447 jobs that showed up at all; 2 of its 20 tasks showed up.

Measured, not estimated: Anthropic's samples of Claude.ai conversations, each tied by a model to an O*NET task, from the Anthropic Economic Index. It says where Claude's use goes, not how much of this job's working time it covers, so it is not on the same scale as the reach above. The releases differ in their sample, their classifier and the smallest share they report (the June 2026 file rounds each task to a hundredth of a percent, so a smaller task reads as none), which is why a change of method starts a new line. At least 96% of each older release's task-tied use matched this site's tasks, and all of the newest. Claude.ai only, so use through other tools and other companies' models is not in it. Every job ranked.
Robots and the physical work
Anthropic rates 27% of this job's working time as physical work. For 5% of the working time, a robot has been shown doing most of the task somewhere: 5% in a purpose-built cell. 0.05 of 3, the 584th highest of the 923 jobs.
- Not physical 73%
- No robot shown 22%
- In a purpose-built cell 5%
Anthropic's rating, not this site's estimate: Claude Opus 5, searching the web, rated each physical O*NET task by the kind of setting in which a robot it could cite (deployed, sold or demonstrated) does most of the task, weighted by its own estimate of each task's share of the time (What work can robots do?, September 30, 2026, data CC BY 4.0; every job ranked). A robot shown somewhere is not a robot in your building: cost, setup and safety decide that. The share within reach on this page still counts no body work. The robot behind each rated task is under the task below.
What changes for the people in this job
From the task-by-task review, by the end of 2028 on the long-run pace at four in five. It says which parts of the work stay with people and which change, not whether anyone keeps a job: that depends on decisions no data set can see.
What stays with people
50% of the working time: the conversation, in-person and hands-on parts of the tasks.
- Assess clients and design programs, the in-person work, 11%
- Coach exertion levels, the in-person work, 5%
- Track progress and adjust programs, the in-person work, 5%
- Maintain fitness equipment, the hands-on work, 5%
- Lead exercise activities, the in-person work, 4%
- Offer options for fitness levels, the in-person work, 4%
What becomes checking the machine
47% of the working time: desk work a model could do by then, in tasks where a mistake costs something or a licensed person signs. A person checks it.
- Plan class routines, costly if wrong, 23%
- Assess clients and design programs, costly if wrong, 11%
- Plan fitness programs, costly if wrong, 10%
- Track progress and adjust programs, costly if wrong, 3%
- Advise on nutrition and lifestyle, costly if wrong, 0.8%
What to learn
- Reviewing work you did not do yourself. The tasks under What becomes checking the machine, where a mistake costs something, stay a person's to check: spotting what a draft gets wrong is a skill of its own.
- Briefing a model and checking its drafts. About 47% of the time is documents and data, the part models reach first: writing a clear brief, giving the right material, and checking what comes back.
- The conversations. About 44% of the time is conversation and in-person work, which this site leaves with people: listening, explaining, persuading, calming.
- Dealing with people outside the organization. Customers, patients, suppliers or the public: trust with them is built by a person.
- Handling protected records. Much of the work touches protected personal records: knowing what may be shared with a model, and how, is part of the job.

Within reach, per task: the share of the task's time whose instances are short enough for a model to finish at the chosen date, pace and reliability. Half by: the date half of that time comes within reach. Made of: how the task's time splits among five kinds of doing. Only the documents and systems parts can count as within reach, so a task that is 30% documents can be at most 30% within reach.

Questions about this job
- How much of the work of Exercise Trainers and Group Fitness Instructors is within reach of AI now?
- An estimated 48% of the working time is within reach of AI models now and 48% by the end of 2028, on METR's long-run pace at four in five. Within reach means a model could finish work that long at that reliability. It is not a forecast of jobs lost or of savings.
- Which tasks of Exercise Trainers and Group Fitness Instructors come within reach first?
- Weighted by the time each takes, the tasks with the most within reach now (projected from METR's April 2026 measurement and Epoch's November 2026 index) are: Plan class routines (100% of the task's time now); Assess clients and design programs (50% of the task's time now); and Plan fitness programs (96% of the task's time now).
- Which tasks of Exercise Trainers and Group Fitness Instructors stay with people?
- Tasks that are people work or body work are not counted as within reach at any date. The largest: Coach exertion levels; Maintain fitness equipment; and Lead exercise activities. Together such tasks are about 30% of the working time, and the people and body parts of the other tasks stay with people too.
- What should Exercise Trainers and Group Fitness Instructors learn as AI takes on more of the work?
- By the job's own task-by-task review, the first things to learn are reviewing work you did not do yourself; briefing a model and checking its drafts; and the conversations. By the end of 2028 on the long-run pace at four in five, about 50% of the working time stays with people, 47% becomes checking a model's work and 1% could be handed over with lighter checks. It says which parts of the work change, never whether anyone keeps a job.
- Do people already use AI for the work of Exercise Trainers and Group Fitness Instructors?
- In the Claude.ai conversations Anthropic sampled for May 2026 and tied to a work task, 0.053% went to this job's tasks, the 227th largest share of the 447 jobs that showed up; 2 of its 20 tasks appeared. Anthropic's labor market measure puts the share of the job's tasks seen in real Claude use at work at 0%. These are measures of use, not of how much of the work AI could finish, and they cover Claude only.
- Can robots do the physical work of Exercise Trainers and Group Fitness Instructors?
- Anthropic's robot exposure rating (September 2026) finds 27% of the working time is physical work, and that a robot has been shown doing most of the task, somewhere, for 5% of the working time. Its index is 0.05 of 3. One example: Somatic BCR (bathroom cleaning robot) for "maintain fitness equipment". A robot shown somewhere is not one in every workplace; this site's own estimates still count no physical work as within reach.
- How is this estimated?
- From the 20 tasks O*NET lists for the occupation, each with an estimated length checked against GDPval and a share of the working time, reviewed one task at a time on September 30, 2026 for what each is made of (documents, business systems, conversation, in person, hands-on), and METR's measurements of how long a task the best AI models can finish, carried forward to the date from the latest, Claude Mythos Preview (early) in April 2026. Data checked November 10, 2026.
