An exercise machine includes a frame and a resistance mechanism attached to the frame. A crank assembly in mechanical communication with the resistance mechanism, and the crank assembly includes a crank arm and a roller connected to the crank arm. A pedal assembly is movably attached to the crank assembly and movable in a performance of an exercise. The pedal assembly includes a pedal beam and a first tensioned element that spans at least a first portion of an underside of the pedal beam. A second tensioned element spans a second portion of the underside of the pedal beam and the roller is disposed between the first tensioned element and the second tensioned element.

A motion base for displacing a force measurement assembly is disclosed herein. The motion base includes a base assembly; a support structure configured to be coupled to the force measurement assembly; a rotatable coupling device, the rotatable coupling device rotatably coupling the support structure to the base assembly; and an actuation system, the actuation system including one or more actuators operatively coupled to the support structure, the one or more actuators configured to displace the support structure relative to the base assembly. In one or more embodiments, greater than 50% of the weight of the support structure is supported by the rotatable coupling device. Also, in one or more embodiments, the motion base may be used for displacing objects other than a force measurement assembly, such as for displacing a flight simulator or a virtual reality simulator.

A fitness equipment unit has a controller that actuates a light between different states in response to service conditions. In one implementation, actuation of the light is based upon a combination of at least two of: a mileage parameter of the fitness equipment unit, a sensed electrical current of the fitness equipment unit, a sensed temperature from the fitness equipment unit and a sensed position of a portion of the fitness equipment unit. In another implementation, actuation of the light is based upon a combination of the first and second service conditions selected from a group consisting of: a connection error service condition; a part wear service condition; a motor/actuator error service condition; a sensor error service condition; a processor error service condition; and a power supply error service condition and further based upon a prioritization of different severity levels of the first and second service conditions.

An elliptical climbing exercise apparatus includes a base frame, a swing unit including a pair of swing arms, a pedal unit including a pair of pedal shafts respectively pivotally connected to the swing arms, a damping unit including a rotating wheel with a spindle, a guiding unit including a pair of cranks respectively affixed to the two opposite ends of the spindle, a pair of rockers respectively pivotally connected to the cranks and a pair of links respectively pivotally connected to the rocker. Cooperation between the base frame, the swing unit, the pedal unit, the resistance unit and the guiding unit is used to achieve a training of the leg muscles.

An elliptical exercise device has a frame supporting guide links and foot support links. A cam system has a vertical control cam portion. Vertical control followers are pivotally connected to a vertical follower support. Mechanical vertical control couplings couple the foot support links to the vertical control followers. A foot receiving area of each foot support link moves in a generally elliptical path when the cam portion rotates about the cam axis.

Belt wear of a treadmill is monitored. In one implementation, samples of electric current draw of a treadmill at different speeds of the treadmill belt of the treadmill are received. A value of each sample is differently weighted based on a speed of the treadmill belt at which the value of each sample was obtained. A belt wear notification is output based on the different weighted values of the samples.
