How To Charge More As A Personal Trainer (Without Losing Clients)

Most UK personal trainers undercharge by roughly 40%. They picked their per-session rate by looking at what the trainer next to them charges, added or subtracted a fiver, and never touched it again.

The result is predictable: full diary, no money, burnout by month 14. (We mapped exactly how this kills careers in Why most personal trainers fail within their first two years.)

Here's how to fix it — without losing the clients you already have. This is the same Pricing framework we teach inside Forge Academy.

Why "What Everyone Else Charges" Is The Worst Way To Price

Your rate isn't a number you copy. It's a number you reverse-engineer from the income you actually need.

The bad way: - "Tom across the floor charges £35. I'll charge £40."

The right way: - "I need £4,500 a month after tax. I want to work 25 client hours a week. With my realistic retention rate, that means my per-session rate has to be £X."

When you run that maths honestly, almost every PT discovers they need to charge 50–100% more than they currently do.

The Three Variables That Set Your Rate

Stop pricing on vibes. Pricing comes from three numbers:

• Minimum viable income — what you need to live and save, after tax and gym rent.
• Sustainable session volume — how many sessions you can deliver per week without burning out (usually 22–28, not 40).
• Retention rate — how long the average client stays. The longer, the more lifetime value per acquisition, the more flexibility on price.

Plug those in and the rate isn't a feeling — it's the answer to a sum.

How To Justify A Higher Rate

You don't justify a higher rate by talking about your qualifications. Nobody buys a PT because of their Level 3.

You justify it by:

• Outcomes, not sessions. "12 weeks to wedding-ready," not "12 sessions of personal training."
• Specialisation. A "personal trainer" charges £40. A "post-natal strength specialist for women returning to lifting" charges £85.
• Proof. Before/after photos, retention numbers, client testimonials — not certifications on a wall.
• Package design. Selling outcomes in 12-week blocks reframes the price from "per hour" to "per result."

Repackage, Don't Just Reprice

If you've been charging £40/session for two years, you can't just message your clients "I'm now £60/session." They'll bolt.

Instead, change the product:

• Bundle sessions into a 12-week transformation programme (12 PT sessions + check-ins + a written programme + WhatsApp support).
• Price the programme at £1,000–£1,800 depending on positioning.
• The per-session maths is now £80–£150 — but nobody is comparing per-session, because you're not selling sessions anymore.

This is the single highest-leverage change most PTs ever make. Done well, it doubles income without adding a single client.

How To Roll Out A Price Rise To Existing Clients

The mistake is doing it badly. The fix is doing it like a professional:

• Give 8 weeks' notice. Never spring it on people.
• Send a personal message — not a group text, not an Instagram post.
• Frame it around what they're getting more of, not just paying more for. (Quarterly progress reviews, a written programme, nutrition check-ins.)
• Lock in existing clients at the new rate via a 6 or 12-month package, paid up-front or by monthly standing order.

In practice, most PTs lose 1–2 clients on a rate rise. They make that back in revenue from the first month at the new price.

What To Do This Week

1. Calculate your minimum viable monthly income, after tax.
2. Decide your maximum sustainable client hours per week.
3. Do the sum. That's your new per-session rate.
4. Repackage it into outcome-based blocks.
5. Pick a launch date 8 weeks out and start telling clients.
