A method for operating a seat system, where the seat system includes a vehicle seat having a plurality of controllable moveable elements integrated into a seat cushion that forms a seat surface and/or into a seat back, includes prompting, during an activated muscle training program, a user on the vehicle seat to exert a pressure with a specific body region of the user on a predetermined region of the vehicle seat in which at least one of the plurality of controllable moveable element is arranged and determining a local and a temporal deviation between a pressure exerted by the user as an input signal and a specification as an output signal.

A fitness-equipment storage bench for use in aiding or supplementing a physical activity in a physical-activity environment whilst enabling storage of fitness equipment, the fitness-equipment storage bench comprising a cuboidal or substantially cuboidal body having first and second ends, two opposing sides between the first and second ends, a top and a bottom; at least one recess formed in one of the said sides; at least one cantilevered bar support in the recess for supporting a dumbbell such that a grip axis of the dumbbell is received entirely within the recess; at least one rotatable element at or adjacent to the first end or the second end to facilitate reorientation of the bench; a pivotable user back support on the top of the cuboidal body; and a stay associated with the back support to hold the back support in at least one raised condition.

An exercise apparatus includes at least one resilient member; a first weight connected to a first end portion of the at least one resilient member; a second weight connected to a second end portion of the at least one resilient member, and a holding member connected to a center portion of the at least one resilient member, the center portion being between the first and second end portions. Another exercise apparatus includes a holding member; a first resilient member having first and second end portions, the first end portion being connected to the holding member; a first weight connected to the first resilient member; a second resilient member having first and second end portions, the first end portion being connected to the holding member opposite the first end portion of the first resilient member; a second weight connected to the second resilient member.

A harness belt system for assisting in the performance of exercises includes at least one belt member, an adjustable belt clip on at least one of two opposing ends of the belt member, and a substantially V-shaped tether having at least a top portion coupled to the belt member and a bottom end. In some embodiments, the top end of the substantially V-shaped tether couples to the belt member and forms at least an angle with the belt member ranging from 91 degrees to 158 degrees. In some embodiments, the system is configured when in use to have the bottom end of the tether tethered to a stationary object and to have the belt member in a closed position for placement of the adjustable belt clip and belt on bent legs over a front of a user's thigh or behind the user's thigh or on a user's calves.

The invention relates to a power training apparatus (10) with a manually actuatable operating element (30) which is coupled via a lever mechanism (20) to at least one unit (39, 41, 42) generating a resistance, wherein the lever mechanism (20) has, at a distance from a grip element (32) of the operating element (30), at least one first joint (26) which is mounted in a first axle (21) via at least one first joint lever (25), and having at least one second joint (35) which is arranged between the at least one first joint (26) and the grip element (32), wherein the at least one second joint (35) is mounted at least indirectly in a second axle (22) via at least one second joint lever (36), wherein one of the axles (21, 22) is operatively connected to the at least one unit (39, 41, 42), and wherein the other of the two axles (21, 22) is blocked or is pivotable about a small angle.

Among others, the present invention provides exercise rollers each including two trays, each tray having an elongated track configured for receiving a roller element. Each roller element is movable along the corresponding track between its two ends, configured to enable a user to perform knee and leg exercise, and receive foot exercise, by moving the roller elements back and forth along the respective tracks.

An exercise apparatus includes a pedal main part on which a user U in a sitting posture places his/her foot, a pedal support part configured to support the pedal main part so that the pedal main part is movable within a predetermined range along a foot-length direction, and a guiding mechanism configured to guide the pedal support part so that the pedal support part moves along a predetermined rotational trajectory in a cyclic manner. According to the above-described configuration, it is possible to prevent each of joints such as a hip joint, a knee joint, and an ankle joint from moving outside the range of movement of the joint. The exercise apparatus may also include a rubber tube that resists the movement of the pedal main part relative to the pedal support part.

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 non-limiting example training instrument comprises a hollow main body formed of an aluminum alloy. The main body is constituted by two gripping portions opposite to each other with a space therebetween and a coupling portion coupling the two gripping portions. A load sensor is arranged in the coupling portion inside the main body. The load sensor is a load cell, a strain gauge affixed to an interior of the main body, and a part of the main body to which the strain gauge is affixed functions as a strain body. Therefore, if a user applies a force so as to bring the two gripping portions close to each other or a force so as to move the two gripping portions away from each other, a load thereof is detected by the load sensor.

Apparatus for bi-directional ankle exercise movements has a main frame with a seat and upwardly extending columns at either side to support a “U” shaped sub-frame, mounted so that it pivots about a horizontal axis passing very nearly through the ankles of a seated user and interconnecting linkages simultaneously enforcing ankle inversion, with plantarflexion and then ankle aversion, with dorsiflexion, about perpendicularly intersecting axes, while resisting such movements, so as to provide bidirectional ankle exercises according to a progressive resistance program, thus strengthening the ankle muscle groups for enhanced balance and dynamic stability.
