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.

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.

A punch-and-cycle exercise device is described. The device includes a cycling mechanism, a frame to which a punch-pad is attached, a plurality of delineated target zones arranged on the punch pad, a sensor unit that may include an impact sensor, an accelerometer, and a single or plurality of hall effect sensors, each communicatively connected to the target zones. A control unit communicatively connects with the sensors, a punch-pad mounted camera, and a display. Gloves with built in magnets and/or unique markings/visual identifiers interact with the sensors and/or camera and provide data to the controller to track user success at responding with correct puncing form to illuminated and sequenced punching programs while cycling. Output can be displayed locally or on any paired device.

An electric magnetic resistance control structure for an exercise machine includes a base; a flywheel, pivotally connected to the base through a rotating shaft, the rotating shaft defining an axial direction, the flywheel, a non-magnetically sensitive layer being coupled to a circumference of the flywheel; a power unit, fixed to the base; a magnetic resistance unit, including a coupling portion corresponding to an arc of the non-magnetically sensitive layer, at least one magnetic member being provided on the coupling portion and kept at a distance from the non-magnetically sensitive layer to generate a magnetic resistance effect; a control unit, configured to control a current applied to the power unit to drive the magnetic resistance unit to move along the axial direction, thereby changing an overlapping area of the magnetic member and the non-magnetically sensitive layer in the axial direction, so as to adjust a magnetic resistance of the flywheel.

A controllable tension force is provided on a first cable. The first cable has a terminal end wherein the terminal end is adapted to attach to an accessory. The first cable is coupled to a motor. The first cable and motor are part of a resistance unit. The resistance unit is coupled to a user support unit having a sliding seat.

A resistive device that enables adjustable resistance in at least one direction using an attachment system and associated eddy current braking system. The resistive device can be bench-mounted, in some embodiments, used for physical therapy caused by neuromuscular diseases, such as stroke and cerebral palsy, orthopedic disorders, general disuse, or even for overall fitness.

A stationary indoor “smart” training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.

A direct-drive bicycle training system and methods of using the same are provided. The system includes a bicycle trainer that rests on a support surface and supports a bicycle frame in an upright manner with respect to the support surface. The bicycle trainer includes a stator, a rotor that rotates with respect to the stator, a cassette affixed to the rotor, a support frame supporting the stator, rotor, and cassette, and a resistance applying mechanism that operatively couples to a portion of a drivetrain of the bicycle frame and applies varying levels of resistance to the portion of the drivetrain. The support frame moves with respect to the support surface in response to a force applied to the drivetrain of the bicycle frame during use of the bicycle training system, generating a more natural movement of the bicycle and simulating on-road use.
