Mr Z
What Makes Mr Z Different From Other AI Health Coaches
Francesco Zen, founder of ZTraining · Last updated June 19, 2026
Where Mr Z starts from
Every rule inside Mr Z came from a real client conversation first — a body fat threshold, a protein correction, a travel protocol — tested across 18 years of one-on-one coaching before it ever became part of an AI. It's one coach's specific, tested approach to real situations, made available at scale.
Built around simplification
The philosophy underneath Mr Z is simplification: fewer decisions, clearer defaults, and real scenarios handled in a single message. A business dinner, a delayed flight, a week with no gym access — these are the actual starting conditions Mr Z is designed around, from day one.
"Real coaching starts from the customer's habits and real-life scenarios — the actual week someone is living."
Who this is specifically built for
Mr Z is built for one person: someone who wants a coach's judgment available all day, woven naturally into a normal life. If that's what you're looking for, that's exactly what this was designed to do.
