A spacer apparatus for maximizing a user's range of motion on a weightlifting exercise machine. The spacer apparatus includes a first interlocking part having a semi-circular body extending between top and bottom portions, and a lock portion extending between first and second ends of the semi-circular body. The first and second ends are spaced and a keyway is between the first and second ends. The spacer apparatus includes a second interlocking part having a body extending, at least partially, between first and second ends, and entirely between top and bottom portions. The body of the second interlocking part has a semi-circular portion with a key portion extending therefrom. In the interlocked configuration, the key portion extends between the keyway such that an outer perimeter of the first interlocking part and an outer perimeter of the second interlocking part are aligned.

An exercise device with a redundant monitoring and control circuit integrated within or otherwise in communication with various components of the exercised device to detect and act on real or possible improper operation of the exercise device. A redundant controller may, based on a determination of a potentially out of specification operating condition of the exercise device, transmit one or more control signals to alter (e.g., reduce or remove) power to the motor of the exercise device. The redundant controller may provide a control signal to a motor power gating device to remove power transmitted to the motor from a power source and/or enable an inhibitor line of a motor controller to disconnect main power from the motor. Controlling the motor power gating device and the inhibitor line may ensure that power is removed from the motor even when a conflicting signal is being transmitted to the motor.

A system for a treadmill with a tread that rotates on front wheels supported on a front axle and rear wheels supported on a rear axle includes a locking mechanism. The locking mechanism comprises a first device associated with one of the front axle or the rear axle and configured to prevent rotation of respective front wheels or rear wheels in a first direction and a second device associated with another of the front axle or the rear axle and configured to prevent rotation of the respective front wheels or rear wheels in a second direction opposite the first direction. The system also includes a controller and a sensor configured to detect a user on the tread. The controller is configured to, in response to the sensor detecting no user on the manual treadmill, engage the locking mechanism to prevent movement of the front wheels and the rear wheels.

An electromechanical device for rehabilitation includes pedals coupled to radially-adjustable couplings, an electric motor coupled to the pedals via the radially-adjustable couplings, and a control system including a processing device operatively coupled to the electric motor. The processing device configured to, responsive to a first trigger condition occurring, control the electric motor to operate in a passive mode by independently driving the radially-adjustable couplings rotationally coupled to the pedals. The processing device also configured to, responsive to a second trigger condition occurring, control the electric motor to operate in an active-assisted mode by measuring revolutions per minute of the radially-adjustable couplings, and cause the electric motor to drive the radially-adjustable couplings when the measured revolutions per minute satisfy a threshold condition, and responsive to a third trigger condition occurring, control the electric motor to operate in a resistive mode by providing resistance to rotation of the radially-adjustable couplings.

Disclosed herein is a quick release weight retaining system configured to improve the safety and effectiveness of a resistance training routine. In an exemplary embodiment, the system includes a weight retainer that is removably mounted to a weight support member. The weight retainer includes an engaging apparatus that can retain and safely release a weight load during exercise. The weight is released by way of the exerciser activating a trigger. A weight can be safely and securely mounted to the weight retainer when pushed against the engaging apparatus.

An exercise machine monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

An exercise machine, such as indoor cycle, including a multi-function wheel brake actuator. A braking force is induced on a wheel, such as through eddy currents or frictionally, by finely or coarsely adjusting the brake actuator. The brake actuator may thus include a knob whereby a user may finely adjust the braking force on the wheel and a lever to actuate interval settings whereby the brake actuator provides set positions of braking resistance. The exercise machine may further include a pop-pin assembly with an over-center cam mechanism to clamp members together. The pop-pin assembly also includes a fine adjustment to adjust the clamping force. So, for example, the seat stem may be clamped to the seat tube, or the handlebar stem clamped to the head tube, with a lever actuating the over center mechanism.

A fitness machine with continuously variable magnetic-controlled damping force and combined with a manual emergency brake includes a fitness bike, a console, a magnetically controlled damping device and a resistance and brake control device. The fitness bike generates and supplies power to the console, magnetically controlled damping device and resistance and brake control device by a rotating flywheel. The magnetically controlled damping device produces continuously variable electromagnetic damping force to the flywheel. The resistance and brake control device allows a user to operate in two different modes of the continuously variable electrically controlled brake and manual emergency brake, and the function of the continuously variable electrically controlled brake may control the flywheel to produce continuously variable electromagnetic damping, so as to achieve the results of generating and supplying the required electric power, providing the continuously variable controlled damping force of the fitness bike, and combining a gradual-change brake and a multifunctional brake.

The present invention provides a weight-adjustable dumbbell component. The weight-adjustable dumbbell component includes a dumbbell base, dumbbell plates, and a dumbbell bar assembly; two ends of the dumbbell base are provided with abutting bumps fitted with inserting holes, limiting mechanisms are unlocked when the abutting bumps extend into the inserting holes, the limiting mechanisms are locked when the abutting bumps are separated from the inserting holes, and the limiting mechanisms are used for limiting relative rotation of a rotating shaft. The dumbbell plates are prevented from loosening during use, parts for unlocking the limiting mechanisms are arranged on the dumbbell base, thus the danger that the limiting mechanisms are unlocked due to improper use is effectively avoided.
