Task exposure index for this occupation
Averaged across the week, this work sits in the middle of the exposure scale: a real part of it is already automatable and a real part is not. O*NET breaks Exercise Trainers and Group Fitness Instructors into 17 distinct work activities. Weighted by how much of the week each one takes, 19% of the job sits at or above the threshold where current systems can do the task end to end. The single largest contributor is "Teach exercise or fitness techniques", which scores 34 and takes roughly 36% of the week. That is the average for the job title. It is not a measurement of any particular person’s week, and the difference between the two is usually larger than the difference between job titles.

Why your own number is different
Two people with the title "Exercise Trainers and Group Fitness Instructors" can spend their weeks on almost entirely different parts of this list, and the parts they choose move the number far more than the title does. Who signs off when the work is wrong, whether the job needs you physically present, and how fast you have picked up the tools all change it again — and none of that is in an occupation average.
The assessment asks you to divide your own week across these activities and answer fourteen questions about the parts of the job an occupation average cannot see. It takes six to nine minutes.

Questions
Will AI replace Exercise Trainers and Group Fitness Instructors?
We do not answer that, because nobody can. What is measurable is how much of the work is already doable by machine: for Exercise Trainers and Group Fitness Instructors, about 19% of a typical week, across 17 activities. The other 81% is not, and what happens to the job depends on things this index does not contain — cost, regulation, who carries the liability, and what the people doing it decide to do next.
What part of this job is most exposed?
"Maintain client information or service records" — it scores 95 out of 100 on task automatability and takes roughly 1% of the week.
What part is least exposed?
"Administer first aid", at 12 out of 100. Work like that is where the hours you protect tend to be worth the most.
Where do these numbers come from?
The activity list and the time weights come from O*NET 30.3, the US Department of Labor's occupational database. The exposure score for each activity is ours, from a published model — the weights, the priors and the limitations are all on the methodology page. No language model is involved in the arithmetic.
Does this apply to my job?
Only roughly. This is the average for the title, and the number that matters is the one for the week you actually work. The assessment asks you to divide your own time across these activities and answer fourteen questions about accountability, the parts of the job that need you specifically, and how fast you have adapted. That produces a different number, and usually a more useful one.
