Ms. Corinne Vasquez-Hale Fitness Manager Northline Strength Club Lafayette, United States
Application for Personal Trainer, Northline Strength Club
Dear Ms. Vasquez-Hale,
I am applying for the personal trainer position at Northline Strength Club. I hold the NASM Certified Personal Trainer credential, current through February 2027, and I currently deliver 34 one-to-one sessions a week to a book of 28 active clients as an employed trainer on hourly pay plus session commission.
The number I would want you to weigh is retention rather than volume. Of the clients who started with me in 2025, 71% were still training twelve months later, against a department average of 58%, and 64% bought a second package. Nine of my 28 current clients came by referral from other clients rather than from the floor. I build the rest through three complimentary movement assessments a week, of which about 44% convert to a paid package, so I am used to filling a book rather than inheriting one.
Your posting mentions a growing older adult membership and a returning-lifter population. Six of my current clients are training around cleared orthopedic rehabilitation, always from the treating physical therapist's written clearance, and I work strictly inside the certification's scope: no nutrition prescription, and referral to a registered dietitian when it is asked for. I would want to build the structured twelve-week onboarding I use now into your assessment process.
My client records and client list are held by my current facility, so I would be starting from your floor rather than arriving with a book, which I would expect and which I have done before. My adult CPR and AED certificate runs through June 2027 and I carry professional liability insurance in my own name. Thank you for your time.
Sincerely, Tunde Adeyemi-Clarke
Summary
A personal trainer cover letter gives a fitness manager the three numbers that price you: sessions delivered a week, client retention over a stated window, and how you acquire clients. This guide gives you a full adaptable letter, how the letter changes between an employed role and a contractor one, and how to write about a book you cannot take with you.
Personal Trainer cover letter examples by experience level
A personal trainer cover letter is a one-page letter giving a fitness manager the three numbers that decide what you are worth to them: how many sessions you deliver in a week, how many of your clients are still training a year later, and how you find clients in the first place.
In practice, managers hire against a revenue line, and they already know what a normal number looks like on their own floor. As a result, managers read a letter with three real figures differently from a letter with none, which is most of them.
Guide to a personal trainer cover letter
That is why this guide and the corresponding personal trainer cover letter example will cover:
- How to structure the letter, paragraph by paragraph
- First, the three numbers that belong in the first two paragraphs
- Then, how to write about a book you are not taking with you
- How the letter changes between an employed role and a contractor one
- Finally, the openings that make a reader finish the file
How to write a personal trainer cover letter
| Paragraph | Its job | Length |
|---|---|---|
| Opening | The role, your certification, sessions a week and book size | 2 to 3 sentences |
| Evidence | Retention with a window, renewal, referral, and how you acquire | 4 to 5 sentences |
| Fit | Something real about their facility, and what you would build there | 3 to 4 sentences |
| Close | Certification expiry, insurance, availability, thank you | 2 sentences |
Three numbers, in the first two paragraphs
A fitness manager reading twenty applications is doing arithmetic. Sessions a week tells them your revenue line. Retention tells them whether that line holds. Acquisition tells them what happens in your first ninety days on an unfamiliar floor.
Write all three plainly: "34 sessions a week to a book of 28. 71% of the clients who started in 2025 were still training twelve months later. I run three complimentary assessments a week off the floor and convert about 44% of them."
If the numbers are small, write them anyway with the period attached. A book of 11 built from nothing in a year is a clearer signal than any adjective, and the manager can see the slope.

How to write about a book you cannot take
In fact, this is the paragraph most trainers get wrong, in one of two directions.
The first mistake is implying you will bring clients with you. If a facility employed you, it almost certainly owns the client records and the relationships, and your agreement may restrict you from soliciting them after you leave. A manager reading a hint that you plan to anyway is thinking about the letter their own leavers might one day send.
The second mistake is hiding the question, which reads as though you have never thought about it.
The line that works says both things at once: "My client records and client list are held by my current facility, so I would be starting from your floor rather than arriving with a book." It says you generate clients, that you understand the agreement you worked under, and that you are proposing nothing awkward. If you are a contractor whose clients contract with you directly, say that instead, and say what you paid for: rent, a revenue share, or both.
Employed roles and contractor roles
Say how you were engaged in the first paragraph: employed, employed plus commission, or independent contractor. For an employed role, lead with acquisition and retention, because the facility supplies the traffic and wants to know you convert it. For a contractor role, lead with book size and tenure, and add your liability insurance and start date. Name something real from the facility: their member profile, their equipment, a program they run.
Do not imply you will bring another facility's clients. Do not write "excellent retention" without a percentage and a window. Do not name a client or describe their body, diagnosis or progress, even without a name. Do not attach before-and-after photographs. Do not claim nutrition prescription or rehabilitation that your certification does not cover.
Certification comes before clients
The Bureau of Labor Statistics states that personal trainers usually must be certified before they begin working with clients, and that most fitness trainers and instructors hold certification in the area of fitness they specialize in (BLS Occupational Outlook Handbook, May 2025 wage data and 2025 to 2035 projections, published 27 August 2026).
The occupation, which BLS calls exercise trainers and group fitness instructors, held 388,400 jobs in 2025, is projected to grow 7 percent between 2025 and 2035, and produces about 68,000 openings a year. Self-employed workers make up 15 percent of it, against 55 percent in fitness and recreational sports centers (BLS Occupational Outlook Handbook, 2025 data).
So the letter has two jobs: clear the credential gate in the first sentence, with issuing body and expiry, and say which side of that 15 percent line you are applying from.
Length, format and sending it
One page, four paragraphs, 250 to 400 words. PDF unless the gym's portal says otherwise, named for yourself and the role: tunde-adeyemi-clarke-personal-trainer-cover-letter.pdf.
Address the fitness manager by name; they are usually on the facility's team page. "Dear Hiring Manager" on a letter otherwise full of numbers looks like a template.
Use the same figures as your resume so the two agree. Our personal trainer resume example is written with the numbers here, and if the role is actually studio teaching rather than one-to-one work, the yoga instructor cover letter is the better starting point.
Key takeaways for a personal trainer cover letter
- First, put sessions a week and book size in the first two sentences.
- Then give retention as a percentage with a window attached, never as an adjective.
- Give your acquisition method and its conversion rate.
- Also, say who engaged you and how they paid you in every role you mention.
- In addition, say plainly that you are not bringing another facility's clients.
- Finally, name the certification, its issuing body and its expiry date.
- Add liability insurance and CPR and AED dates in the closing paragraph.

Personal trainer cover letter questions, answered
How long should a personal trainer cover letter be?
One page, four paragraphs, 250 to 400 words. Managers read these between sessions and skim for the numbers, so lead with them.
What if my client numbers are small?
Write them with the period attached and let the slope speak. "A book of 11 active clients built from nothing in twelve months, all from floor assessments" is stronger than any claim about dedication, and a manager can extrapolate it.
Should I mention my rate or commission expectations?
Not in the letter. Say how you were engaged so the structure is clear, and leave the rate for the conversation. What does belong is how many sessions a week you want to deliver, since that is what the manager is planning around.
Do I need to say anything about scope of practice?
One clause is enough, and it is reassuring rather than limiting. Saying that you refer to registered dietitians and physical therapists rather than advising outside the certification tells a facility that their insurer will be comfortable with you.
How do I write to a gym I have never trained at?
Visit it, or read the membership pages first: the member profile, the equipment, the programs they run and who manages training. One accurate sentence about their floor beats a paragraph about your philosophy, and it cannot be pasted into the next letter.
