An exercise table was an apparatus in sickbay of the Constitution-class USS Enterprise. It was used in conjunction with a pair of foot pedals which were above it. To test the vital signs of a patient during exercise, the patient lay on the table and pumped the pedals; a body function panel monitored the patient's readings. A person could take this test while wearing a shirt or while topless.
In 2269, while inhabiting Kirk's body, Janice Lester used this apparatus. McCoy, unaware of Lester's transferred consciousness, told "Kirk" that his heart would last forever. (TOS: "Turnabout Intruder")
