The real numbers, training twice a week
| Typical cost | Monthly, 2x/week (~8 sessions) | |
|---|---|---|
| UK average, outside London | £30–£80/session | £240–£640/month |
| London / premium trainers | £50–£150+/session | £400–£1,200+/month |
| Mr Z | Flat rate, no per-session cost | $59/month, or $299 for 180 days |
Personal training rates are in pounds, based on published UK industry pricing guides, 2026. Individual trainer rates vary by experience, location, and specialism. Mr Z is priced in US dollars.
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.
