Choosing the right personal trainer: what to look for

Hiring a personal trainer is one of the most personal purchases you can make. You're buying time, expertise and trust — often with someone you've never met. This guide gives you a simple framework for choosing the right person the first time.
Start with verification, not Instagram
A polished Instagram grid tells you about marketing, not coaching. Before you look at anything else, confirm the trainer is verified on a register like REPs. That single step covers qualifications, insurance and identity — the three things that protect you legally and physically.
Match the speciality to your goal
A trainer who specialises in postnatal recovery is rarely the right pick for a powerlifting meet. On REPs, every professional lists their specialisms, the populations they work with, and the settings they coach in. Filter ruthlessly — the right specialist will get you further in eight weeks than a generalist will in six months.
- Define your goal in one sentence before you contact anyone.
- Filter by specialism, location and setting (gym, home, online).
- Shortlist three professionals and read every review on their profile.
- Send the same enquiry to all three and judge them on the reply, not the rate.
Questions worth asking on the consultation
Most trainers offer a free 20-minute consultation. Use it. Ask how they structure the first six weeks, how they measure progress, what happens if you don't see results, and how they handle injury or illness. A good professional will have clear, calm answers — not a sales pitch.
"Pay attention to how the trainer listens during the consultation. The best coaches ask more questions than they answer."
