Exercise apparatus for attachment to a chair having a center support post. The apparatus has a foot support, wheels mounted on the respective ends of the foot support for rolling on a floor, and a resilient member that exerts resistance as the foot support is moved. One or more sensors are coupled to the wheels for monitoring a user's body functions during exercise. The sensors provide inputs to software in the user's computer that calculate the level of the user's exercise activity as the user is at work on his/her computer. The results are displayed on the computer's monitor.
