Leverage machine exercises

Leverage machines are plate-loaded or selectorized units with a fixed path: chest press, row, hack squat, and similar frames. The catalog slug is leverage_machine. These are not cables and not a Smith bar. The advantage is a guided path and often a seat that removes the need to balance a free weight. This hub lists those machine movements so a search for machine exercises that map to this slug has a URL. A cable fly stays on cable. A barbell bench stays on barbell. Cards name the target muscle so a chest-press machine still belongs to the chest atlas. Similar exercises prefer other leverage-machine rows. No brand names, no pin-vs-plate debate. Published exercise counts on the page update with the catalog so this introduction stays about anatomy and equipment rather than a stale number.
