Improvements to a desk and exercise semi-recumbent bicycle is disclosed, the desk allows a person exercising while utilizing the desk with a computer, as a table or read a book. The desk has a 3-way adjustment relative to the seat for elevation of the desk, angle, sliding forward and backward of the desk or the proximity of the desk relative to the chair and or the pedals. The desk pivots to allow the desk to be easily tilted towards the user when they are studying and tilted away from the user when the user wants to exit the exercise bicycle. The dimension from the seat to the pedals is adjustable to accommodate these different desires. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. A recording mechanism can count distance, elapsed time, calories or other information.

A method for cooling a motor on a treadmill includes rotating a flywheel with a drive motor. A ring member coupled to the flywheel is be rotated with the flywheel. A pressure drop is generated in an annulus of the ring member between the drive motor and a lift motor. Intake air is drawn in a first direction across the lift motor toward the pressure drop.

An exercise apparatus (5) comprising: a user input device (5i) mounted to a frame for movement in a first direction (6f) and for movement in a second direction (6o) that is generally opposite the first direction (6f), the user input device (5i) comprising a manually engageable device (5e) interconnected to a first fan (20) adapted to be rotatably driven to exert a first resistance (R1) on rotation in one direction and a second fan (22) adapted to be rotatably driven to exert a second resistance (R2) on rotation in one direction.

A resistance adjusting apparatus is disposed on a frame and has a rotating member, a magnetic resistance member, and a wind resistance member. The rotating member has an axle rotatably disposed on the frame, an assembly seat fixedly disposed on the axle, and a magnetic wheel detachably disposed on the assembly seat. The magnetic resistance member is disposed on the frame, is located out of the magnetic wheel, and has an adjusting seat disposed on the frame and multiple magnetic elements. The magnetic wheel is inserted into an inner space of the adjusting seat. The magnetic elements are disposed in the adjusting seat and are located in the inner space of the adjusting seat. The wind resistance member is detachably disposed on an outer surface of the magnetic wheel. The wind resistance member and the magnetic resistance member are independent and can be detached individually.

A pedal drive system, in particular for an electric vehicle or a training apparatus, and for generating electrical power from muscle power of a user with at least one pedal and an electric generator, connected mechanically with said at least one pedal, is provided. To improve the haptic feel and feedback at the pedal, a control unit is provided for controlling a feedback torque, applied at said pedal, wherein the control unit comprises a haptic renderer, configured for control of said feedback torque based on at least one predefined pedal reference trajectory.

The present invention concerns an improved rowing machine, for the execution of gymnastic exercises similar to strokes and the like, comprising actuating means movable between a rest position and a working position, and a first braking device, operatively connected to said actuating means configured to brake the motion of said actuating means during the passage from said rest position to said working position, characterized in that said rowing machine comprises a second braking device operatively connected to said actuating means, said second braking device being configured to brake the motion of said actuating means during the passage from said rest position to said working position.

A treadmill can include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a drive motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, a runaway load component in electrical communication with the drive motor. The runaway load component draws electrical power generated by the drive motor during a runaway motor condition.

An adjustable pedal assembly for an exercise machine, such as an elliptical trainer, may include a link and a pedal pivotally connected to the link The pedal assembly may further include a damping assembly, which may provide dynamic damping to the pedal during use of the exercise machine. The damping assembly may be adjustable such that a user can select the level of damping. The damping assembly may include at least one resilient member configured to engage the pedal for damping pivotal movement of the pedal, and an actuator operable to selected a level of damping provided to the pedal by the at least one resilient member.

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.

Apparatus (10) for performing an arm curl exercise comprising: a frame (12), a seat (16), an elbow pad (19) an input arm assembly (24) interconnected to a resistance mechanism (42) and a manually graspable mechanism (30h), the seat (16) being arranged relative to the input arm assembly (24) to position the user in a user start position (USP) that enables the user to manually engage the manually graspable mechanism (30h) with a posterior surface (PSE) of the user's elbow user's elbow (13e) engaged with the engaging surface (ES) of the elbow pad (19), the input arm assembly comprising a first arm (30r) and a second arm (30f) pivotable around a first linear axis (AA).
