About this site
Last reviewed October 20, 2026
Two kinds of page
The site has 886 exercise pages, and they are not all the same kind of thing. 20 are full guides, written for this site: setup, cues, mistakes, drawbacks and the questions people search for. The other 866 are reference entries: steps, start and end photos, the muscles involved, and swaps on other equipment where the data supports one. Every page says at the bottom which kind it is.
Where the reference entries come from
The exercise list, the step-by-step instructions, the muscle and difficulty labels and all 1,772 photos come from the Free Exercise DB, an open dataset released into the public domain. Its labels have not been re-checked one by one here, and some are odd: it rates simple stretches such as the lying hamstring stretch as advanced, for example. The muscle diagrams, the category pages and the swap lists are computed from those labels, so an error in a label shows up in all three. If you spot one, the contact form is the fastest way to get it fixed.
How the full guides are written
Each guide is written from the coaching articles and coach Q&A threads listed under “Sources” at the bottom of the page: 56 links across 19 publishers, including Barbell Medicine, StrongFirst and Bret Contreras. Where those sources disagree, as they do on squat bar position or how upright a row should be, the guide says so instead of picking a side. Nothing in a guide comes from filming or coaching anyone, because nobody here does that.
What you won't find
No star ratings, no “best exercise” rankings, and no popularity order: there is no data here that could honestly support one, so lists run guides first and then A–Z. No ads, no affiliate links, no account, and nothing for sale.
Who keeps it
Bryant Hagadorn, a software engineer and recreational lifter. Not a coach, not a physical therapist, and not a doctor. That is the reason every guide links its sources: you should be able to check a claim against someone who does this professionally.
Not medical advice
If a movement hurts, or you are training around an injury, see a physical therapist or a sports-medicine doctor. A web page cannot watch you lift.
