Sethi's concrete method for doubling a service business's income, worked through live with a hypothetical personal trainer. Beyond automatic aggressive investing, you increase income on four levers: get more clients (via referrals), raise the lifetime value per client (packaged add-ons like meal planning), extend how long clients stay (six-month plans at a small discount), and move up-market. Each hour is your currency, so fill every hour and maximise its return.
Origin
Sethi role-plays a $100/hour personal trainer and walks through doubling revenue lever by lever.
Core principles
- 01Your time is the currency in a service business — fill every hour and maximise its return.
- 02Referrals from happy clients are the cheapest new-client channel.
- 03Packaged add-ons raise lifetime value without more hours.
- 04Longer commitments (six-month plans) stabilise revenue.
How to run it
- 1
Get more clients via referral
Ask current clients 'I've got a few slots — who would you recommend?' and run free group sessions to attract leads.
Pro tip A free Saturday session for clients' friends is a low-cost client-acquisition funnel.
- 2
Raise lifetime value
Package add-ons (meal planning, macros, food-delivery partnerships) that add thousands per client.
- 3
Extend duration
Offer a six-month plan at a small (~5%) discount to lengthen how long clients stay.
- 4
Move up-market
Once your calendar is full, specialise or serve higher-paying segments (executives, celebrity clients, virtual).
Pro tip Productise with video courses that 'scale while you sleep'.
Watch out Up-market moves are an advanced step — master filling and pricing your hours first.
In the wild
A $100/hour trainer with three-month average clients adds referrals, meal-planning packages, and six-month plans.
→ The four levers together can double revenue and boost profit substantially.
Common mistakes
Only chasing more clients
Everyone's first instinct is 'find more clients', ignoring the bigger gains from lifetime value, duration, and price.
Is it for you?
Best for
Service providers (trainers, coaches, consultants) trading time for money who want to scale income.
Not ideal for
Product or software businesses where the levers differ from a time-for-money model.
