An improved apparatus for physiotherapy includes a lever arm. A biasing device pivotally biases the lever arm about a pivot axis. There is a support configured for supporting the lever arm above an exercise equipment. A harness is configurable on a torso of a user to couple the user to the lever arm. The pivot axis corresponds to an anatomical longitudinal axis of the user and the torso of the user is biased by the lever arm about the anatomical longitudinal axis.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

Control system of a cycling simulation device, said device comprising a support frame, with which a user carries out training by acting on the pedals of said bicycle, a flywheel rotating around a main shaft, connected to said coupling members, and a braking device, acting on said flywheel, comprising: a control logic unit, capable of connecting in transmission and reception with a remote device, by which a user can set one or more training parameters, and a torque sensor for detecting and sending to said control logic unit a signal related to the torque acting on said main shaft during the rotation of said flywheel, and said control logic unit being configured so as to adjust the braking force exerted by said braking device on said flywheel as a function of training parameters and of signal related to the torque acting on said main shaft detected by torque sensor.

A stationary exercise device includes a support structure and one or more input members such as pedals, handles, or other feature movably connected to the support structure. A movable output member such as a wheel is movably mounted to the support structure, and operably connected to the one or more input members such that movement of the one or more input members causes the output member to move. A resistance member interacts with the output member when the output member is moving to generate a variable resistance force tending to prevent movement of the output member. The variable resistance force may at least partially simulate the effects of inertia and/or momentum.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

A resistance device includes a first rotating assembly having a first rotating member, and a second rotating assembly having a second rotating member and a plurality of magnets. A transmission unit is connected to one of the rotating assemblies for driving rotation of the same. A drive unit is connected to the other one of the rotating assemblies, is configured to receive a control signal, and is configured to drive rotation of the other one of the rotating assemblies according to the received control signal. Eddy currents generated by the first rotating member provide resistance to the transmission unit. A resistance training machine having the resistance device is also disclosed.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

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 method for displaying archived exercise classes comprising displaying information about archived exercise classes that can be accessed by a first user via a computer network on a display screen at a first location, wherein the first user can select among a plurality of archived classes, outputting digital video and audio content comprising the selected archived class, detecting a performance parameter for the first user at a particular point in the selected class, displaying the performance parameter on the display screen, and displaying performance parameters from a second user at a second location on the display screen such that at least one of the performance parameters from the first user and at least one of the performance parameters from the second user at the same point in the class are presented for comparison.

A climbing exercise machine includes a beam supported on two columns supported on a base. Two handles are movably supported on the columns, respectively. The handles are movable in opposite directions. Two treads are movably supported on the columns, respectively. The treads are movable in opposite directions. An input axle is supported on the columns. The input axle is rotated as the handles and the treads are moved. A transmission case connects the input axle to an output axle. A disc is connected to the output axle. A frame is connected to the beam. A resistance element is supported on the frame. The resistance element includes a magnet. The resistance element is movable relative to the disc to adjust magnetism exerted on the disc by the magnets.
