What the training data shows

These are operating records, not a controlled trial. They describe what happened among people who chose to train at Hero's Journey and kept training — a group that is self-selected by definition. They are strong evidence that the format works for the people who use it, and weak evidence about anyone who would not have joined in the first place.

We publish the population behind each figure for that reason. A 95% attendance rate across all bookings means something different from a 95% rate among members who lasted a year, and the difference matters if you are deciding whether to join.

Body composition and strength figures compare an athlete against their own earlier results, not against other athletes. Individual outcomes vary with starting point, consistency and how closely the program is followed — and, as the attendance figure implies, showing up is the variable that moves results most.

Most gyms cannot publish numbers like these because they never collect them. Access-based gyms know when you badged in, not what you lifted. The measurement here is a by-product of how the training itself runs.

Every strength station has a tablet that already knows your history: it shows the exercises for the day, the weight you lifted last time, the reps you completed and what to load today. You confirm what you actually did, so the record is what happened rather than what was planned.

Every athlete trains in a heart rate monitor that reads every second and displays on the studio screen, so the coach can see who should push and who should ease off. And every two months the Assessment Center records body composition, VO2 max, strength benchmarks and endurance, which is what makes first-to-follow-up comparison possible at all.
