What each one actually does
- A personal trainer runs the hour you're in the gym: technique, programming, a spot, a push on the last set.
- A testosterone coach runs the rest of the week: food, sleep, which days you train, what you cut out — and checks in every night.
What they cost
A personal trainer typically runs €150–400 a month, depending on how often you see them. A testosterone coach here is €49 a month, with a call every night.
Get a trainer if…
- You've never lifted and need someone watching your form.
- You're coming back from an injury and need a hands-on programme.
- You train harder with someone standing next to you.
Get a coach if…
- You know what to do and stop doing it by Wednesday.
- The problem is outside the gym — food, sleep, late nights.
- You want someone to notice when you go quiet, every day, not once a week.
Or both
Plenty of men do both: a trainer a few times a month for technique, a coach every day for the follow-up. The coach builds the trainer's sessions into the week and asks whether they happened.
