Abstract:
1. A lat exercise machine for exercising the latissimus dorsi (“lat”) muscles of the back, comprising: a main frame having a front end and a rear end; a user support pivot mount; a user support which is adapted to support a user in an exercise ready position when performing a lat exercise, the user support being pivotally mounted on the user support pivot mount for pivotal movement relative to the main frame in a predetermined pivotal movement path about a user support pivot axis from an exercise start position during performance of a lat exercise by a user supported on the user support; the user support pivot mount comprising a four bar pivot linkage between the user support and main frame, the four bar pivot linkage defining the location of the user support pivot axis whereby a gravitational center line extending vertically through the user support pivot axis extends through a user engaging part of the user support during at least part of the pivotal movement of the user support along said predetermined pivotal movement path; one exercise actuating user engagement device movably mounted relative to the main frame and having at least one handle gripped and actuated by a user positioned on the user support in order to perform the exercise; a connecting linkage which links movement of the user engagement device to movement of the user support whereby the combined movement of the user engagement device and user support defines a lat exercise; and a load which resists movement of at least one of the user support, user engagement device, and connecting linkage; whereby the user performs a lat exercise on the machine by actuating said one user engagement device only.
