A resistance applying device for use with an exercise apparatus includes a rotatable shaft, a rotatable impeller coupled to the rotatable shaft, a sealed housing surround the rotatable impeller, the sealed housing containing a fluid that provides resistance against the rotation of the impeller, and a barrier located between the rotatable impeller and the housing, the barrier and the rotatable impeller being configured to provide for relative movement between the barrier and the rotatable impeller.

Exercise resistance device

A physical activity monitor, during a first period, records data characterizing a physical activity by a user, and an exercise device uses the recorded data of the physical activity monitor to simulate the physical activity for the user during a second period.

Electronic exercise system

The present invention is directed to a bicycle trainer that permits a bicycle to be used for stationary riding. The bicycle trainer has a modular fluid resistance unit wherein resistance is provided by the rotation of an impeller against a fluid contained in a sealed housing. The resistance unit provides selectively variable resistance, is quiet to use, and simulates bicycle riding on a road.
