What it actually does

Built to do a few things very well.

Reads your body, not just your weight

Send a photo and Mr Z estimates your body composition, then sets your nutrition targets from that, not a generic calculator.

Remembers everything, every time

No re-explaining your situation. It picks up exactly where your last conversation left off and adjusts your plan from there.

Technique enhancement

Ask, and learn how to activate your body the right way for any movement.

Available the moment you need it

2pm or 2am, mid-flight or mid-set.
You message, it answers.

Why this isn't just another AI

Built by one coach, not a prompt.

Most AI fitness tools are a generic chatbot wearing a fitness skin. Mr Z is built from Francesco Zen's eighteen years of real-world coaching results, encoded into a system equipped for the situations real life actually throws at you: travel, plateaus, no time, no motivation. Powered by Claude, Anthropic's most advanced AI.

The only way to actually know is to try it.

Questions

Before you start.

Is this just ChatGPT with a fitness prompt?+
No. Mr Z runs on Claude, but the coaching logic underneath was built from one coach's eighteen years of real client results, not a generic prompt.
Do I still need a real coach?+
Depends what you need. Mr Z handles day-to-day questions, nutrition, technique, accountability. If you want someone reviewing your actual training in person, that's ZTraining.
Can I cancel anytime?+
Yes. Manage or cancel your subscription anytime from inside Telegram.
What if I run out of messages on Core or Premium?+
You can upgrade to the next tier anytime. It takes effect immediately.
