An exercise device for compression exercises is adjustable in height and in compression force. The device includes a central housing and a plurality of plungers extending from a top side. A support member is attached to the housing on a bottom side. The support member is movable longitudinally relative to the housing and plungers from a fully retracted position to a fully extended position and is lockable in a plurality of intermediate longitudinal positions to vary the height of the device. Each plunger is operatively associated with an internal bias member that biases the plunger away from the housing. Resistance force on a plunger is adjustable via changing tension of the associated bias member with an adjustment knob to finely adjust tension. An installed bias member is removable and replaceable with a different bias member to coarsely adjust tension.

An isometric force resistant exercise tool has a left handle form interfaced to a right handle form over an axle shaft locked to the right handle form, the axle shaft supporting a pressure plate, a compress able spring or set of springs, and a compression adjustment handle threaded onto the axle shaft and abutting the compress able spring or spring set, the pressure plate adjacent in assembly to a friction-resistive material fixed on the left handle form, the left handle form including a piston form interfacing with a ring housing on the right handle form, the piston form adjacent in assembly to a friction-resistive material fixed on the right handle form. Gripping the handle forms and rotating the against force resistance exercises one or more muscle groups.

A hand training device and corresponding method are used for sensing and measuring a capacitance corresponding to the pressure or force applied by the hand or fingers of the user. This hand training apparatus has slots for the index finger, the middle finger, the ring finger, and the pinky finger. The data obtained from the device can be utilized to create a 3-D model to indicate grip strength exerted by the hand or pinch strength.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

An exercise apparatus configured to combat postural maladaptations is provided. The exercise apparatus includes a rigid central spherical body having a channel passing through the center thereof through which a resilient band may be passed. The resilient band is removable and may be made of any suitable resilient material, such as, for example, a rubber material. The central spherical body may be formed of any suitable rigid or semi-rigid material that resists deformation.

A motor skill activity book for individuals having poor fine motor skills can be configured to be laid flat in an elongated fashion and to be closed into a compact rectangular prismatic form. Panels of the motor skill activity book can each include a face layer defining a cutout section, a backing layer, and at least one intermediate layer stacked between the face layer and the backing layer. The panels can be coupled via bindings such that the motor skill activity book can be configured between an open state in which the panels can lay flat such that the front face of each of the panels is substantially flush with the front faces of the other of the panels, and a closed state in which the panels stack on top of each other.

In various embodiments, an apparatus for exercising can include a housing, a first inner tube, a second inner tube, and a compression spring operable to resist motion when compressed. The first inner tube is coupled with a first end of the compression spring and the second inner tube is coupled with a second end of the compression spring. In addition, the apparatus can also include an extension spring inside the housing. Furthermore, a portion of the compression spring and a portion of each of the first and second inner tubes are inside the housing. Note that a first end of the extension spring is coupled with a first handle or loop and the second end of the extension spring is coupled with a second handle or loop. The extension spring is operable to provide resistance during pulling motion away from center of the apparatus.
