A muscle trainer comprising curved, elongate spring elements is disclosed. The spring elements are arranged with facing concave sides and include end areas formed at each of the ends of the spring elements. The muscle trainer includes a first joint element being formed at a first end area of each spring element and a second joint element being formed at a second end area of each spring element. The spring elements are connected at their two end areas via joints formed from the joint elements. The first joint elements are designed as brackets having a bend in the direction of the concave side of the respective spring element and in each case at least partially enclosing the second joint element of the respective other spring element. A method for producing the muscle trainer and its use as a hand trainer are disclosed.

Methods for instructing a user to perform head and neck exercises with head and neck apparatuses are disclosed. The apparatus may include a member operatively arranged with a valve mechanism with a threshold pressure. The apparatus may further include an acoustic apparatus, membrane, chromogenic material, or moveable element that may be configured to respond when the pressure within the member is greater in magnitude than the threshold pressure. The head and neck exercise apparatus may also include a member operatively arranged with an acoustic apparatus, membrane, chromogenic material, or moveable element that may be configured, without a valve mechanism, to respond when the absolute pressure within the member is greater in magnitude than a threshold absolute pressure.

Disclosed herein are various embodiments of an exercise apparatus. In certain embodiments, an exercise apparatus comprises a frame and a seat assembly, the seat assembly comprising a seat, the seat configured to move between a first position and a second position, wherein the first position accommodates use of the exercise apparatus by a user sitting on the seat and wherein the second position accommodates use of the exercise apparatus by a user sitting in a wheelchair. The seat assembly may be pivotably coupled to the frame. The seat assembly may comprise a stop configured to inhibit movement of the seat, and may further comprise a biasing element that is biased to disengage the stop.

A variable stride exercise apparatus may provide a novel linkage assembly and corresponding exercise apparatus suitable for linking circular motion to relatively more complex, generally elliptical motion. Left and right cranks are rotatably mounted on a frame. A foot supporting linkage is movably connected between a rocker and the left and right cranks in such a manner that may provide variable paths of motion controlled by a user of the apparatus.

An office chair that is ergonomically configured to allow for the coordination of stretches to the pectoralis minor muscle, trapezius muscle, and scalene muscles to open up the thoracic outlet, release muscle tension, and reinforce proper structure is provided. The stretches may be performed by an average human user while sitting in the office chair throughout the workday. The ergonomically configured chair assembly may have a brace supported by the seatback and extending downwardly therefrom over a left and right shoulder of the seated average human in a cantilevered fashion and an arm restraining device positioned rearward with respect to the rear face of the upstanding seat back.

The disclosure provides an apparatus for exercising muscles of the head and/or neck. The apparatus comprises a harness, and a plate is pivotably connected to the harness. The plate is movable between a collapsed position and an exercise position where a back of the head of the user can engage with the plate. A biasing member biases the plate towards the collapsed position.

The present invention provides for an exercise apparatus comprising a pair of footplates arranged for reciprocal movement on respective support means, the support means extending outwardly from either side of a central frame portion of the apparatus, the footplates being arranged to receive a pair of human feet and so as to be moved by a user in a reciprocal manner in the direction of the support means as part of an exercise routine, and wherein the apparatus includes handgrip portions extending from the central frame portion of the apparatus, the handgrip portions being arranged for movement, such as for example upward and/or downward movement against a resilient bias during the exercise routine.

An exercise apparatus has an arrangement of strategically placed attachment points on a wall structure, floor and ceiling that enables easy attachment and detachment of a variety of resistance devices (e.g., a handheld and/or inline cable operated resistance creation device, or a stretch band resistance device) to any of the vertical and/or horizontal structures, thereby providing a nearly 360 degree dimensional point of resistance to perform a wide variety of exercises for different muscle groups and subgroups of the body. In one embodiment, an adjustable resistance creation device includes a cable that winds onto a cable spool and the adjustable resistance creation device providing a constant force of resistance throughout the performance of an exercise movement as the cable is pulled and unwinds from the spool. The adjustable resistance creation device may be incorporated within a gym grip or, alternatively, attached to an exercise machine.

Disclosed herein are various embodiments of an exercise apparatus. In certain embodiments, an exercise apparatus comprises a frame and a seat assembly, the seat assembly comprising a seat, the seat configured to move between a first position and a second position, wherein the first position accommodates use of the exercise apparatus by a user sitting on the seat and wherein the second position accommodates use of the exercise apparatus by a user sitting in a wheelchair. The seat assembly may be pivotably coupled to the frame. The seat assembly may comprise a stop configured to inhibit movement of the seat, and may further comprise a biasing element that is biased to disengage the stop.

An exercise machine is disclosed. The exercise machine comprises a tension generating device. The exercise machine comprises a translatable arm mount coupled to the tension generating device. The exercise machine comprises an arm coupled to the translatable arm mount. The exercise machine comprises a cable coupled to the tension generating device via the arm.
