1. An apparatus for exercising latissimus dorsi muscles (“lats”) of a user, the apparatus comprising:
a frame providing a user space in which the user is located when exercising the lats using the apparatus;
a lever having a handle and rotatably mounted to the frame, the lever configured to be rotated with respect to the frame by the user via the handle about a working axis through a working range of motion (“ROM”) in a concentric direction starting at a first rotational position and ending at a second rotational position and configured to be rotated in an eccentric direction that is opposite the concentric direction and ends at the first rotational position, wherein the lever includes a rigid working arm configured to force an arm of the user to maintain a substantially constant angle between a forearm and an upper arm of the user throughout the working ROM to isolate the lats;
a resistance system;
a range selector configured to selectively couple and decouple the lever with the resistance system and to selectively modify the working ROM;
wherein, when the lever is coupled to the resistance system via the range selector, the resistance system acts on the lever to provide a resistance force that resists rotation of the lever in the concentric direction.
