Mr Z
An AI Coach That Actually Knows Coaching, Not Just Workouts
Francesco Zen, founder of ZTraining · Last updated June 19, 2026
Over 18 years of coaching, the thing clients credit most isn't a formula. It's being asked how they're actually doing — and having that answer change what happens next.
Why personality came before logic
The first thing built for Mr Z wasn't a macro calculator. It was his personality. Most people expect knowledge and strategy to be the differentiator in coaching — and they matter — but the real edge has always been care: asking how someone's day went, how they're feeling, before deciding what they need.
That kind of conversation surfaces details a static intake form never would. Mr Z is built to start there — genuinely understanding the person and respecting their boundaries — before it offers anything.
What this looks like in practice
If someone is low on energy and tired, handing them a hard session and saying "let's go, you've got this" isn't good coaching — it's a missed read. Mr Z is built to mirror the person's actual state first. That's not a soft add-on to the method; it's the starting point of it.
"My secret isn't strategy. It's care."
Sustainability over intensity
Mr Z's personality is built in service of sustainability, wellbeing, and an easygoing relationship with training — not constant pressure. It carries the same coaching methodology and nutrition logic Francesco Zen has used for 18 years, but it starts from intention, not data.
