US Patent 12109456 Modular exercise machine

An exercise machine includes a first housing, a central electromagnetic resistance unit, a resistance mechanical interface, and a mechanical expansion portion. The resistance mechanical interface includes a spool and a cable configured to provide a force from the central electromagnetic resistance unit in response to a control interface that receives commands from an exercise actuator. The cable extends out from a first side of the first housing. The mechanical expansion port is configured to link the first housing to a second housing via a mechanical attachment. The mechanical expansion port is located at a second side of the first housing. The second side of the first housing is adjacent to the first side of the first housing.
