Interview tips for this role
- Include a practical assessment where the candidate coaches you through an exercise and provides corrections.

- Look for trainers who talk about client outcomes rather than just their own fitness achievements.
- Assess their communication style. The best trainers adapt how they speak to each individual client.
Frequently asked questions
What qualifications should a personal trainer have?
In the UK, a Level 3 Personal Training qualification accredited by CIMSPA (Chartered Institute for the Management of Sport and Physical Activity) is the minimum standard. REPs (Register of Exercise Professionals) membership demonstrates professional commitment. Additional specialisations in areas like nutrition, pre/post-natal or corrective exercise add significant value.
How do you assess a personal trainer practical skills?
Have them demonstrate coaching an exercise, including cueing, correction and progression options. Observe whether they assess before prescribing, explain the purpose of exercises and watch for safety. A short practical session with a real or simulated client reveals more than any interview question.
What makes a great personal trainer versus a good one?
Great trainers get results for every type of client, not just the naturally motivated. They combine technical knowledge with genuine empathy, adapt their communication style and build programmes that fit real lives. They also understand the business side, retaining clients long-term through consistent value rather than dependency.
