Patent ID: 7927265

Claim:
A resistance training apparatus comprising: a frame assembly; a shaft rotatably mounted to the frame assembly; a first disk mounted to the shaft, and a first one way clutch configured to transfer rotating torque to the first disk in a first direction only when rotating torque is imparted to the shaft in the first direction; a second disk mounted to the shaft, and a second one way clutch configured to transfer rotating torque to the second disk in a second direction only when rotating torque is imparted to the shaft in the second direction; a first caliper frictionally engaging the first disk; a first adjustment means for allowing selective adjustment of frictional resistance imparted by the first caliper onto the first disk; a second caliper frictionally engaging the second disk; a second adjustment means for allowing selective adjustment of frictional resistance imparted by the second caliper onto the second disk; wherein, the first and second adjustment means each include: an actuator housing, an actuator adjustment wheel with a hollow hub, the actuator wheel coupled to the actuator housing at the hub, an actuator shaft positioned within the housing such that its first end extends from the housing to engage a respective caliper piston, the shaft positioned to pass through the hollow hub such that its second end extends outwardly a distance from the actuator adjustment wheel, and, a spring configured to bias the shaft into engagement with the respective caliper piston, and wherein rotation of the actuator adjustment wheel selectively varies a biasing force of the actuator shaft onto the respective caliper piston.
