What this comparison isn't saying
This isn't an argument that a personal trainer is a bad investment. In-person spotting, hands-on form correction, and the accountability of a fixed appointment are real, and they're not things an AI replicates. What this comparison shows is access: for roughly the cost of a single session, Mr Z is available every day of the month, not just on the days you've booked and paid for.
