Pick a machine and watch the muscles light up in order of effort — primary movers first, then helpers, then stabilizers. Free, no signup, works on any phone.
Any AI can restate a spec sheet. None of them can let you pick a machine and watch a muscle respond. That difference is the whole point of this site.

Most equipment sites are a spec sheet with affiliate links stapled on. These are the three rules that keep this one from becoming that.
Anatomy you can verify
Muscle names follow standard anatomical terminology, and the activation levels are drawn from published resistance-training literature. If something looks wrong, check it against any anatomy atlas — we would rather be corrected than trusted blindly.

Honest about age
Every review carries the date it was last checked, and products that have been discontinued are labelled as such instead of quietly left online. A 2020 review that never got updated is not a review — it is a trap.

Commission never decides
We earn a commission when you buy through some links. It never changes a recommendation — some of the products we rate highest pay us nothing at all, and we say so on the page.
