About The Fitizen
Library last reviewed: June 2026
What this site is
The Fitizen is an independent exercise-form reference: 886 movements you can browse by muscle, body part, or equipment, plus 20 in-depth form guides for the lifts where technique matters most. No account, no paywall, no app — just the information you'd want before putting a bar on your back.
Where the information comes from
The catalog is built on the open-source Free Exercise DB, which we've cleaned, reorganized, and extended. The in-depth form guides are distilled from the working consensus of the strength community: established coaching resources and the recurring advice in powerlifting and bodybuilding forums, cross-checked against each other. Where the community genuinely disagrees (low-bar vs. high-bar squats, for example), the guides say so rather than picking a winner. Each in-depth guide links its sources in a “Keep Reading” section, so you can check the receipts.
Who runs it
The Fitizen is built and maintained by Bryant Hagadorn, a software engineer and recreational lifter. Not a coach and not a doctor — which is exactly why every guide is grounded in the linked coaching sources rather than personal authority, and why corrections are taken seriously.
What this site is not
It is not medical advice, and it is not a substitute for an in-person coach. If a movement causes pain, or you're training around an injury, see a qualified professional — a form guide can't watch you lift.
Corrections
If a cue is wrong, a muscle listing is off, or a guide contradicts good coaching practice, we want to know and we'll fix it. The library carries a visible “last reviewed” date so you can tell how current the information is.
