An adjustable resistance system for use with an indoor cycle comprising a magnetic resistance assembly, a friction brake assembly, and a resistance adjustment assembly.

Among other things, a rowing technology includes a first rowing machine having an electromagnetic brake providing a resistance to a rower of the machine in each rowing stroke of a series of rowing strokes of the rower An electronic controller causes the resistance of the electromagnetic brake to vary over each rowing stroke in a profile that emulates resistance to which another rower in a shell on water or on a second rowing machine is subjected in each rowing stroke of a corresponding series of rowing strokes.

A folding exercise bike can be easily assembled and disassembled/folded for storage and/or transportation. The exercise bike can include a telescoping seat, a telescoping stem, a fold to stow handlebar and fold down locking legs. Various configurations for the exercise bike can be used. The exercise bike can include a wireless transmitter to transmit cycling data to a user's portable electronic device.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

A stationary exercise machine according to the present disclosure may include a frame, a crankshaft rotatably supported by the frame, first and second lower linkages, and first and second crank arms connected to opposite sides of the crankshaft such that rotation of either of the crank arms causes rotation of the crankshaft. The lower linkages may be operatively connected to the crankshaft and to a respective one of first and second pedals. Each of the lower linkages may include a reciprocating member operatively connecting one of the pedals with one of the crank arms. Each of the lower linkages may include an adjustable linkage connected between the reciprocating member and the respective crank arm, the adjustable linkage may vary a distance between an output end of the reciprocating member and an input end of the crank arm. Each of the pedals may be pivotally connected to the respective reciprocating members.

A towing equipment used to train athletes' speed, strength and agility is disclosed to include a training unit, a magnetic resistance unit and a transmission mechanism. By an elastic training belt of the training unit, the towing equipment is connected to the human body. The kinetic energy generated by the human body pulling the elastic training belt is transmitted to the magnetic resistance unit through the transmission mechanism to generate resistance. The magnetic resistance unit includes a magnetic device set and an adjustment device set. The user can adjust the resistance generated by the magnetic device set through the adjustment device set. The magnetic device set includes a resistance wheel set on the frame body and a bearing block set corresponding to the resistance wheel. Use the overlap area of a magnetic field in the resistance wheel and the bearing block to generate magnetic flux.

An exercise apparatus having a frame with attachments to multiple independent bidirectional resistance devices used by arms and/or legs of a user to provide resistance against movement of the user's appendages in two substantially opposed directions. The resistance devices may have a mechanism to control bi-directional resistance. The movement of the user's appendages in bi-directional resistance offers near full body exercise of agonist/antagonist muscles using flexion and extension action of larger muscle groups in a gait pattern, simultaneously. Hand engaging members attach to arm resistance devices and foot engaging members attach to leg resistance devices. The exercise apparatus may include an attached inclined backboard, mat, bench, or cushion to fully or partially support the user. The exercise apparatus may have separate height and/or length adjustment mechanisms for adjusting a range of motion of the user's appendages.

A magnetic resistance structure and an exercise machine having the same are disclosed. The magnetic resistance structure includes a seat body, a turning disc unit, a movable seat, a control unit, and a magnetic field component. The turning disc unit is pivotally connected to the seat body in an axial direction. The turning disc unit has a non-magnetic induction part extending in a radial direction. The control unit is connected with the movable seat for controlling the movable seat to approach or move away from the non-magnetic induction part. The magnetic field component includes a first component and a second component. The first component is located on the seat body. The second component is located on the movable seat. The first component and the second component selectively generate a magnetic field by changing their relative positions.

A motor brake device of an exercise apparatus includes a motor, a brake device and a lifting device. The brake device has a rotating disc and a magnetic brake mechanism. The rotating disc is coaxially mounted on a motor shaft of the motor. The magnetic brake mechanism has at least one magnetic portion. The lifting device is configured to drive the magnetic brake mechanism to move between a first position where the magnetic portion is located close to the rotating disc and a second position where the magnetic portion is located away from the rotating disc. The second position is located higher than the first position. When there is no electric power supplied to the exercise apparatus, the magnetic brake mechanism can move downward to the first position to stop rotation of the motor shaft by gravity due to potential difference between the second position and the first position.
