## Notes

- [What belongs on an outdoor fitness trail, and what gets ignored](https://toffoligiochi.com/notes/outdoor-fitness-trail-equipment.html): Wear patterns show heavy use on pull-up bars, parallel bars and step boxes, and near-zero use on lever machines without resistance. Station spacing of 50-150 m for trails versus 2-5 m for clusters, pull-up bar heights around 2.1-2.3 m with a 1.2-1.4 m low bar, surfacing behaviour under use, and a five-station minimum circuit.
- [Fall height decides the surfacing, and the surfacing decides the budget](https://toffoligiochi.com/notes/fall-height-and-surfacing.html): Free height of fall measured from the user rather than the structure; the roughly 600 mm threshold above which impact attenuating surfacing is required and the 3000 mm usual maximum. Capability by surface type, why loose fill loses depth where landings occur, why outdoor fitness sits under a different standard than children's playgrounds, and how falling zones constrain circuit spacing.
- [Public circuits are built for people who do not need them](https://toffoligiochi.com/notes/training-from-a-desk.html): Outdoor fitness equipment assumes the user can already perform a pull-up, excluding the sedentary population it is intended to serve. The specific deficits of desk-based work and screen-based recreation, including digital gaming, and four entry movements (hang, inverted row, step up, support hold) available on standard equipment.
