A pedal assembly for electromechanical exercise or rehabilitation of a user is disclosed and can include pedals to engage appendages of a user. A spindle supports each pedal and has a spindle axis. A pedal arm assembly is located between the spindle and a rotational axle of the equipment. The pedal arm assembly is radially offset from the spindle axis to define a range of radial adjustability for the pedal relative to the rotational axle. The pedal arm assembly can include an electrically-actuated coupling assembly to adjust the radial position of the pedal in response to a control signal, and regulate motion of the user engaged with the pedals.

A rowing machine provides resistance to both pushing and pulling motions of both the upper body and lower body. A linear sliding seat that moves in a longitudinal direction is connected to a flywheel to provide resistance to back and forth motion. A handle arm is also connected to the flywheel to provide resistance to back and forth motion. The flywheel creates cyclical back and forth motion of the seat and handles for the user to push and pull with the arms and legs. The handle arm and seat may be linked together, and then one or the other linked to the flywheel, providing synchronization between the handlebar, carriage and flywheel.

An improved strength machine is at least partly distinguished by the following features: having a housing (20), a housing frame (141), an inner supporting structure (145) and/or an inner frame (145, 150), having a rotatable flywheel weight (13) mounted in the housing (20), on the housing frame (141), on the inner supporting structure (145) or on the inner frame (145, 150), the flywheel weight is fitted on a shaft (12) or is seated on a shaft (12), having a flexible pulling element (3), the flexible pulling element (3) is attached to the shaft (12) or a reel (95) which is mounted on a freewheel bearing (94), which is pretensioned by means of a spring arrangement (96) in the wind-up direction of the pulling element (3).

An exercise machine having a force transmission assembly rotatable in first and second directions, first and second wheels rotatable in first and second directions, a first directional coupler that couples the force transmission assembly to the first wheel when the force transmission assembly rotates in the first direction, and a second directional coupler that couples the force transmission assembly to the second wheel when the force transmission assembly rotates in the second direction. The first directional coupler allows the force transmission assembly to rotate with respect to the first wheel when the force transmission assembly moves in the second direction, and the second directional coupler allows the force transmission assembly to rotate with respect to the second wheel when the force transmission assembly moves in the first direction. A resistance mechanism may be configured to resist rotation of the first and second wheels independently from each other.

A physical training apparatus includes a housing, a flywheel mechanism accommodated in the housing, the flywheel mechanism including a spindle, at least one flywheel mounted on the spindle and bearings to support the spindle in the housing, a windable pull element, such as a pull cord or band, which is arranged to be wound up the spindle and unwound from the spindle, and a handgrip attached to the pull element. The spindle includes a spindle end portion. The flywheel is exchangeably mounted on the spindle end portion against a stop located on the spindle. A fastening knob is releasably coupled to the spindle end portion and adapted to engage the flywheel and force it against the stop located on the spindle.

A resistance system, which can be suitable for incorporation in exercise equipment, is a hybrid resistance assembly having at least a first and a second resistance unit. The first resistance unit can be of a first type and the second resistance unit can be of a second type. The first resistance unit can be an inertial resistance unit, which incorporates an inertial load that creates resistance influenced by the inertia of a movable mass, such as a rotatable flywheel. The second resistance unit can be a static or non-inertial resistance unit, such as a displacement resistance unit, which incorporates a load that creates resistance influenced by displacement (e.g., linear or rotational displacement) of an input to the displacement resistance unit.

A climbing machine includes a resistance device, a driving device, and two climbing devices. The driving device comprises an upper wheel set, an axial wheel set, and a lower wheel set. The axial wheel set includes a first axial wheel and a second axial wheel. Through a plurality of connecting members, the alternate up and down movements of the climbing device drive the upper wheel set and the lower wheel set to rotate in a first direction, the upper wheel set drives the first axial wheel to rotate in a second direction, and the lower wheel set drives the second axial wheel to rotate in the first direction.

Electromechanical rehabilitation of a user can include receiving a pedal force value from a pedal sensor of a pedal; receiving a pedal rotational position; based on the pedal rotational position over a period of time, calculating a pedal velocity; and based at least upon the pedal force value, a set pedal resistance value, and the pedal velocity, outputting one or more control signals causing an electric motor to provide a driving force to control simulated rotational inertia applied to the pedal.
