How to choose a personal trainer in Trento: the questions worth asking

Qualifications: what is worth asking

When you look for a personal trainer, the first sensible question is about preparation: a sport science degree, recognised certifications, continuing education. It is not nitpicking, because a title on its own says little unless you understand what it means in practice. An analysis of 615 job postings for exercise professionals in the United States (Pojednic and colleagues, 2024) found that over 70% required a bachelor's degree, but that the education and certification requirements varied widely from one posting to the next. A 2025 narrative review of 15 studies (Shivgulam and colleagues) points to a similar lack of uniformity: in the scientific literature, the qualifications of so-called "exercise professionals" differ greatly from one setting to another. These are North American settings and they do not describe the situation in Italy, but they are a reminder that it is reasonable to ask calmly about a trainer's education, specific certifications and experience with people who start from a situation similar to yours.

How a trainer thinks matters too, not just the title. A qualitative study published in 2024 in Psychology of Sport and Exercise (Oi, Vijayan and Ler) interviewed 16 fitness trainers in the Kuala Lumpur area, Malaysia, to understand how they decide what goes into a programme. The interviews revealed a difference between individual and group training: in personal training, the feedback given to the client was more personalised. This is a descriptive piece of work, with a small sample from a single geographic setting, so it does not prove that an individual programme delivers better results. It does confirm, though, that asking how a programme is built and adapted is a sensible question, and that a well-prepared professional's answer should be about you, not about a one-size-fits-all scheme.

The first conversation comes before the programme

A good first meeting feels more like a conversation than a sales presentation. It should bring out your training history, past injuries, any health conditions your doctor has mentioned, the time you can realistically commit and what you expect from the process. If these questions never come up, it is hard for the programme to be built around you. For the same reason, an initial consultation is a good sign only when it is a genuine assessment and not a showcase of the service.

There is a limit to keep in mind, though: a questionnaire filled in before you start is useful, but it does not replace a medical assessment. In an Italian study of 464 men (mean age 38.4 years) enrolled in a workplace screening programme (Palermi and colleagues, 2022), applying pre-participation questionnaires alone would have left 24% of the abnormalities found by the full medical evaluation undetected. The sample was male-only and came from a single programme, so the numbers should not be generalised, but the practical message is simple: if you have a known cardiovascular, metabolic or joint condition, or any doubt, talk to your doctor first. A serious trainer will be the first to suggest it.

Personalisation and reviews: a programme is not a template

The difference between a plan built around you and a standard template shows over time. In a randomised study carried out in a fitness club (Storer and colleagues, 2014, Journal of Strength and Conditioning Research), 34 men aged 30 to 44 trained three times a week for 12 weeks: half with a qualified personal trainer applying an evidence-based periodised programme, half on their own. The supervised group increased lean body mass by 1.3 kg on average, while the self-directed group showed no change, and chest press strength and leg power also improved more. The sample was small, entirely male and drawn from a single club, however, and the result depends on both the quality of the trainer and the structure of the programme: it is not a promise that holds for everyone.

That is why it is worth asking how often the programme is reviewed, on what basis, and what happens if an exercise does not work or causes discomfort. There is no ideal schedule for everyone: what you can reasonably expect is that changes come with a clearly explained reason, and that nobody asks you to ignore pain.

How progress is checked

Ask, too, how results will be verified. You do not need a complicated spreadsheet: a few clear reference points, revisited over time, are enough. A meta-regression of 122 evaluations of interventions to increase physical activity and improve eating, with 44,747 participants in total (Michie and colleagues, 2009, Health Psychology), estimated an average effect of 0.31 (95% confidence interval: 0.26 to 0.36). The technique that explained the largest share of the differences between studies was self-monitoring, that is, keeping track of what you do: interventions that combined it with at least one other self-regulation technique derived from control theory averaged 0.42, against 0.26 for the others.

These are standardised effect sizes, not kilograms or percentages, and they refer to behaviour-change programmes in general, not to personal training itself. They do not tell you how much you will improve, but they suggest that having clear reference points and reviewing them with someone is a habit worth looking for in a programme.

The environment and a practical summary

Then there is the environment. Training in a space where only one person trains at a time is different from training in a shared room: the attention you receive changes, and so does the freedom to get something wrong and fix it without feeling watched. We have no studies to cite on this point, and it is mostly a matter of personal sensitivity, so visiting the studio before deciding is time well spent. In short, before starting, ask: how is the programme personalised, how often is it reviewed, what training does the trainer have, how does the initial consultation work and how is progress measured. The studies cited have limits in population, duration and sample size, and no programme, however well built, can guarantee a specific result.
