7 Questions to Ask Before Hiring a Personal Trainer
60% of PT clients leave within 3 months. In most cases, the mismatch was predictable — they just didn't ask the right questions before committing.

These seven questions cut through marketing and reveal whether a trainer is qualified, compatible with your goals, and worth £40-90 per hour. Ask all seven before your first paid session.
1. "What accredited certification do you hold, and can I verify it?"
This eliminates 35% of the market immediately. Legitimate trainers respond with a specific certification name and number: "NASM-CPT, number 12345678."
If they say "I did a course online" or can't name the accrediting body, they're not certified to a professional standard. Our certification guide lists every accredited body worth recognising.

2. "How many clients with my specific goal have you trained?"
Specificity matters more than total experience. A trainer with 100 hours of marathon preparation experience is more valuable to a runner than one with 5,000 hours of general personal training.
Good answer: "I've trained 20+ clients for half-marathon prep. My average client improves by 15 minutes over 12 weeks."
Bad answer: "I work with all types of goals."
3. "What does your assessment process look like?"
Quality trainers screen before they train:
- Movement assessment (overhead squat, single-leg stance)
- Health history questionnaire
- Baseline measurements relevant to your goal
- Lifestyle and availability discussion
A trainer who skips assessment and jumps straight into "let's start with bench press" is guessing at your programme.
4. "Can I see a sample 4-week programme?"
The programme reveals the trainer's methodology. Look for:
- Progressive overload — weights or reps increase week to week
- Exercise variety within structure — not random
- Periodisation — different phases for different adaptations
- Regression options — alternatives for exercises you can't yet perform
- Rest programming — recovery is planned, not accidental
No written programme = no systematic approach. This is the biggest red flag in personal training.
5. "What happens between sessions?"
A trainer's value extends beyond the 60-minute session. Quality trainers provide:
- Written programme for your independent training days
- Nutrition guidance or referral to a registered dietitian
- Check-in messages between sessions
- Form review via video
- Programme adjustments based on your feedback
If the answer is "nothing — I'll see you next week," you're paying for a spotter, not a coach.
6. "How do you track and measure progress?"
"You'll feel it" isn't measurement. Ask what metrics they track:
- Strength benchmarks (specific lifts, rep maxes)
- Body composition (if relevant to your goal)
- Performance tests (run times, endurance benchmarks)
- Mobility assessments
- Subjective markers (energy, sleep quality, mood)
Good trainers show you data at 4-week intervals. They don't wait until you ask "am I making progress?"
7. "Can I do a trial session before committing to a package?"
The only way to evaluate coaching quality is to experience it. A trial session reveals:
- Communication style (motivational vs technical vs quiet)
- Attention to detail (do they notice form errors?)
- Preparation (did they plan the session based on your assessment?)
- Punctuality and professionalism
- Whether you actually enjoy training with them
Any trainer who refuses a trial session is either overconfident or hiding something. Most professionals welcome it — it demonstrates their value.
The Decision Framework
After asking all seven questions and completing a trial:
| Signal | Proceed | Walk Away |
|---|---|---|
| Certification | Accredited, verifiable | Unverifiable or unaccredited |
| Experience | Specific to your goal | Generic "all goals" |
| Assessment | Structured screening | No assessment |
| Programming | Written, progressive | No plan, winged sessions |
| Between sessions | Active communication | Zero contact |
| Tracking | Objective metrics | "You'll feel it" |
| Trial | Available and welcomed | Refused or pressured to skip |
Score 6-7 green signals: commit with confidence. 4-5: proceed cautiously with a short-term package. Below 4: keep looking.
FAQ
Should I interview multiple trainers? Yes. Trial 2-3 before committing. The experience difference between a 3/10 and a 9/10 trainer is dramatic.
What if the trainer gives great answers but bad sessions? Actions > words. The trial session is the definitive test. Some trainers interview brilliantly and coach poorly. Trust what you experience, not what you hear.
Is price a good indicator of quality? Weakly. Expensive trainers can be mediocre. Affordable trainers can be exceptional. Credentials, experience, and trial quality are better indicators.
