The difference between a programme and a coach.

A programme is a static document. Coaching is a continuous conversation.

Until now, only the wealthy or the elite had access to the conversation. Everyone else got the document. Written once, never updated, indifferent to recovery, indifferent to perceived exertion, indifferent to whether last Tuesday actually happened.

The standard training plan

Written once. The same session, whatever happened.

Rewritten weekly. Every session informed by the last.

How it works.

Read

The system reads what actually happened: perceived exertion, completion, recovery. Not what was prescribed.

Write

It rewrites what comes next. Volume, intensity and exercise selection adjust to the athlete you are this week.

Repeat

Every block compounds on the last. The longer you train, the better it knows you.

“I've trained off standard programmes for years with every team I've played for. This is the first time a programme actually knows me and adapts to my needs.”

Today's session, written for you.

The home screen shows what to train today, why this load was chosen, and what the system noticed about last week. On a rest day it tells you it's a rest day, and that's the whole interaction.
