An exercise apparatus includes a pair of apparatuses wearable on feet of a user. Each apparatus is configurable between expanded configurations and compressed configurations to simulate a selected motion when the user wearing the pair of apparatuses travels by foot. One of the apparatuses can move towards an expanded configuration while the other apparatus moves towards a compressed configuration.

A magnetically-controlled damping device has a fixing disk, a rotating disk, a plurality of friction-proof sleeves, a plurality of brake shoes, a plurality of magnets, an elastic element, and an operating element. The rotating disk has a plurality of guiding rods sleeved by the friction-proof sleeves respectively. By adjusting a distance between the magnets and a rotating wheel, a damping value of the magnetically-controlled damping device can be adjusted. Moreover, since the friction-proof sleeves are between the guiding rods and the guiding grooves, the guiding rods do not wear out. The magnetically-controlled damping device can provide a more stable damping value and a longer service life.

Controlling an exercise machine includes receiving a stream of measurements of extension of a component of an exercise machine. It further includes characterizing the stream of measurements including detecting at least one extremum having at least one extremum parameter. It further includes matching the extremum parameter with a previously determined signature associated with a user. It further includes changing an output of the exercise machine based at least in part on the match.

An exercise machine includes a first and second vertical member extending from a base section. A moveable section is mounted to said first and second vertical members and is configured to move vertically along said first and second vertical members as well as horizontally. A third and fourth vertical member also extend from said base section. A first and second functional training device are mounted to said third and fourth vertical members, respectively, and are configured to be selectively secured at various locations along the same. At least one cable connects a resistance device to the moveable section as well as to the functional training devices.

A device for supporting the head of a person, having at least two lips that are placed around a first main axis and around a second main axis oriented perpendicular to the first main axis and that form, together with at least one securing system, a closed curve with a hollow space formed therein for supporting the person's head. The securing system can be designed, by matching a circumference of the curve, to form a homogeneously acting positive engagement or frictional engagement between the lips and the person's head. Also, a combination of a training apparatus and a device for supporting the head of a person is provided.

Wearable assistance devices and methods of operating the same are provided. A wearable assistance device includes an upper-body interface with a front side and a rear side and a lower-body interface with a front side and a rear side. The assistance device also includes one or more elastic members, each of the elastic members mechanically coupling the upper-body interface to the lower-body interface and extending from the rear side of the upper-body interface to the rear side of the lower-body interface and along a back of the user so as to provide an assistive force parallel to the back of the user. Further, the assistance device also includes a clutch mechanism associated with each one of the elastic members, the clutch mechanism configured for selectively adjusting the assistive force provided by the one of the elastic members.

Apparatus for performing an arm extension exercise comprising: a frame, a seat having a seating surface (S), an elbow pad having an engaging surface (ES), an input arm assembly interconnected to a resistance mechanism and a manually graspable mechanism, the input arm assembly being adapted to reside in a start motionless position (SMP) that disposes the manually graspable mechanism in a start exercise position (SEP) that is disposed vertically above UW) the user's elbows, the input arm assembly being pivotable around a linear axis disposed rearwardly of the user's elbow.

A manipulator (110) for e.g. gait training is constructed from an Evans mechanism with an additional degree of freedom to provide a two dimensional workspace.

A gym tower which includes a base and a plurality of internal weights vertically stacked on the base. A frame is connected to the base and extends upward from the base to engage with the plurality of internal weights. A top plate is connected to the frame, so that the base and the plate enclose the plurality of internal weights within the frame. The tower also includes a spine is adapted to selectively engage the plurality of internal weights. A main pulley is connected to the top plate and a main cable is fed through the main pulley. The main cable is connectable to the spine at a first end and includes a connector device at a second end. The tower also includes a rod adapted to engage with the spine and to select an internal weight and is adapted to secure to external weights.
