Abstract: An exercise machine has a flywheel, a rotary input member, and a clutch mechanism that is positionable in a freewheel position in which rotation of the rotary input member causes rotation of the flywheel and wherein thereafter ceasing rotation of the rotary input member permits continued rotation of the flywheel. The clutch mechanism is alternately positionable in a direct drive position in which rotation of the rotary input member causes rotation of the flywheel and wherein thereafter ceasing rotation of the rotary input member prevents continued rotation of the flywheel. Advantageously, movement of the clutch mechanism from the freewheel position to the direct drive position is prevented when rotation of the rotary input member is out of synchronization with rotation of the flywheel.

Abstract: Systems and methods are for determining and indicating a desired corrective change in exercise technique to an operator and optionally for determining and indicating a correct or incorrect fit between an operator and an exercise equipment. The systems comprise an exercise apparatus that is engaged by an operator at least a first contact location; a first load sensor device that senses an operator-applied load amount at the first contact location; a controller that determines a desired corrective change in exercise technique and/or the correct or incorrect fit between the operator and the exercise equipment based at least upon the operator-applied load amount at the first contact location and a current body weight of the operator; and an indicator device that indicates the desired corrective change in exercise technique and/or correct or incorrect fit, for example to an operator or an instructor.
