Qualifications
Ask what qualification the trainer holds, who awarded it and whether it is relevant to your goals. Check continuing professional development, appropriate insurance and first-aid provision. Do not infer a lack of qualifications simply from a low price.
Experience
Ask whether the trainer has worked with people whose goals or circumstances resemble yours. A newly qualified trainer is not automatically a poor choice, but they should recognise the limits of their experience and refer on when appropriate.
The training
Good personal training means sessions designed around your needs and goals. Ask how the plan is adapted, how progress is reviewed and what support is included between sessions. Compare what you actually receive rather than assuming that expensive means personalised.
Advice
Discuss what nutrition guidance is included and whether the trainer is qualified to provide it. General healthy-eating support differs from medical nutrition therapy. A trainer should recognise when a registered dietitian or another healthcare professional is the appropriate contact.
Commitment and practical fit
Agree suitable session times, communication, cancellation terms and realistic expectations. Reliability and a respectful working relationship matter at every price point; neither is guaranteed by the fee.
Your health
Tell the trainer about relevant limitations and ask how they would adapt activity or seek specialist input. Personal training is not an operation or medical treatment. Be cautious about guaranteed transformations or claims to treat conditions outside the trainer’s qualifications.
If budget is an issue, group or paired training may spread the cost. Ask for current prices and what is included rather than relying on an old London price range. The best option is one that fits your needs, budget and ability to keep attending.
