How to Start a Personal Trainer Business
From certification and a place to train to the first client package you bill, set out step by step.
Training clients on your own account means more than programming sessions: you need the right certification, a place to train, a registered business, tax IDs and insurance, and a way to sell and bill packages. This guide walks through that setup. Session packs, memberships and late cancellations are explained line by line in the personal trainer invoicing guide in the links.
On credentials, the BLS fitness trainers and instructors profile (In the US, last modified August 27, 2026) says "Personal trainers usually must be certified before they begin working with clients or with members of a gym or health club." It also says "Most trainers or instructors also need certification in cardiopulmonary resuscitation (CPR) and first aid, as well as in use of automated external defibrillators (AED)."
Starter invoice, sample figures only: a 10-session pack at 10 × $65.00 = $650.00 plus a fitness assessment at 1 × $80.00 makes $650.00 + $80.00 = $730.00. Swap in your own rates.
Step-by-step startup guide
Follow these steps to launch your personal trainer business on solid footing.
- 1
Get certified and keep it current
The BLS (In the US, last modified August 27, 2026) says "Many organizations offer certification." Pick one that fits the training you plan to offer, and keep CPR and first aid up to date.
- 2
Decide where you will train
Wherever you plan to train, whether a rented gym slot, a studio, clients' homes, parks or video sessions, ask your city or county what applies and an insurance agent about cover.
- 3
Set up and register the business
The SBA (In the US, SBA, checked October 31, 2026) says "You’ll need to choose a business structure before you register your business with the state." Talk the options through with a lawyer or accountant.
- 4
Get an EIN
The SBA (In the US, SBA, checked October 31, 2026) says "Your Employer Identification Number (EIN) is your business’s federal tax ID number." The IRS (In the US, IRS, last reviewed or updated October 16, 2026) says "You never have to pay a fee for an EIN."
- 5
Arrange insurance
The SBA (In the US, SBA, checked October 31, 2026) says "You also may be legally required to purchase certain types of business insurance." Ask an insurance agent what policy fits training clients in person and online.
- 6
Sell the first package and bill it
Write down what each pack contains, when it expires and your cancellation notice, then invoice the pack when the client signs up.
Tips for starting your personal trainer business
- Hold back part of each payment for tax; the IRS (In the US, IRS, last reviewed or updated October 30, 2026) says "The self-employment tax rate is 15.3%."
- Keep a session log per client, so you and the client can both check what's left on a pack.
- Put your cancellation notice period on the booking form, not only on the invoice.
- Note each client's start date and goals; renewals can be easier to sell when progress is written down.
