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 as part of their physical, the patient lay on the table and pumped the pedals while a body function panel monitored their readings. A person could take this test fully clothed or shirtless.
Shortly after arriving aboard the Enterprise that year, Charles Evans used the exercise table. After observing his results, Dr. McCoy declared that Evans was "four-oh, 100%, sound of wind and limb." (TOS: "Charlie X")
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")
