How we work

gymnical turns published training formulas and public data into calculators and charts you can use in the gym or on the road.

How pages are written

Our text is drafted with help from AI writing tools. The numbers do not come from those tools: they come from the formulas and data sets named on our Sources page, and the calculators compute them with code we test against hand-worked examples.

How pages are checked

Before a page goes live, automated checks look at its links, its numbers and its build. Every week someone on our team reads a sample of newly published pages and fixes what is wrong. What we learn from those fixes changes how the next pages are written.

Corrections

What we never do

No fake reviews, no invented quotes, no made-up coaches or experts, and no before-and-after photos.
