Fitness

About

A free exercise library that shows each movement in 3D and explains the research behind every cue.

Who makes it

Raturi Fitness is written and built by Nitin Raturi, a software engineer who trains with a push/pull/legs split. Nitin is not a clinician, physiotherapist or certified coach, which is why the site is built the way it is: every page comes from a research doc with checked sources, and health content waits for review by a qualified professional.

Review status

No page on the site has had a professional review yet. Until a reviewer is in place, every page shows "Last checked by the author" with a date, carries the medical disclaimer, and never claims professional review. Pages still in draft are hidden from search engines and say so at the top. When a physiotherapist, sports physician or certified strength coach reviews a page, their name, credential and the review date will appear on it.

How pages are made

  1. Each exercise starts as a research doc: setup, joint angles, muscles, mistakes, safety and programming, with a source and certainty level for every claim.
  2. The doc is checked against the editorial policy, then turned into the page and its motion data.
  3. The 3D demo is tuned against the doc on six body types and four camera angles.
  4. Pages are updated when new evidence appears or a reader reports an error.

The 3D bodies

The figures are built from the MakeHuman base mesh, skeleton and body-shape targets, which the MakeHuman community released under the CC0 1.0 public-domain licence. The animation runs in your browser with three.js. Icons are from Lucide (ISC licence).
