Abstract: A support member is connected to an exercise device, and extends upward from the connection point to a point above the exercise device. A kill switch is attached to the upper end of the support member. One or more connectors extend downward from the kill switch, and attaches to a body harness configured to be secured around a user's torso and/or other body part(s). In the event of a fall, the downward force created by the weight of the user triggers the kill switch, causing the operation of the exercise device to cease immediately. The length of the connector(s) should provide enough slack so that as the user moves, the kill switch is not falsely triggered the user's movement in performing various exercises. Likewise, the length of the connector(s) should be short enough to catch and suspend the user in the air in the event of a fall.
