Abstract: An exercise system includes a load bearing element having a control element. It further includes a resistance mechanism responsive to a signal from the control element. The signal from the control element is selectively rejected based on state information relating to a state of the load bearing element.

Abstract: An exercise accessory includes a load bearing shaft. It further includes a ring-shaped actuator oriented substantially concentrically to the shaft that is responsive to radial pressure from a user. The radial pressure from the user causes a control signal to be transmitted from the exercise accessory to an exercise machine.

Abstract: In response to physical connection of an exercise accessory with a portion of an exercise machine, an identifier of the portion of the exercise machine is received. A signal including the identifier of the portion of the exercise machine is transmitted.

Abstract: An exercise machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.
