Guides

The reference library
that also runs in the app.

Evergreen training guides across four categories: fuel, recover, learn, prepare. Same taxonomy as the Engine tab inside the Pelaris app, so the training content surfaced to you while you train has a permanent public home here.

Why these four categories

The Pelaris Engine re-ranks research and guides for your day based on your program phase, sport, injuries, and recent views. Out here the ranking is editorial, but the categories are the same so anything you bookmark on pelaris.io slots into the same mental map you use inside the app.

Evidence

The science that backs our numbers

Every guide here, and every number Pelaris puts in front of you, stands on published sports science. We keep the whole shelf in the open: 16 sources checked by hand, from the World Health Organization, the American College of Sports Medicine and peer-reviewed journals, each one named beside the claim it supports. Read how we estimate VO2max and fitness age, what your body measurements can and cannot tell you, and how far to trust a projected one rep max or race time.

View the science and sources

Straight to a topic: VO2max and fitness age, body metrics and what they mean, or strength and race projections.

The Engine Room is where Pelaris surfaces fuel, recover, learn, and prepare content ranked for your current day, sport, and program phase. For the theory that drives the programs themselves, see the methodology library. For news and commentary, see the blog.
