A vertical knee raise machine that is portable, which can be folded into a compact unit for storage but than be quickly and easily set up for use. The machine includes a foldable tripod base and folding arms to allow it to be folded up for ease of storage.

An apparatus and method for training muscle strength and mobility in the neck, and providing a dynamic resting position without pressure on the neck, of a person when in lying position is disclosed. The apparatus includes a base element, a head support suspended floating above the base element, and a neck support rising from the base element. The neck support provides a fulcrum that defines head movement to a pivoting motion about a first axis (X) which runs sideways substantially along the shoulder line of the body, a pivot connection between the head support and the base element defines head movement to a pivoting motion about a second axis (Y) transversely to the first axis, and by its floating suspension the head support defines head movement to a pivoting motion about a third axis (Z) running in the longitudinal direction of the neck and body.

Apparatus and method for facilitating a dynamic plank exercise comprises a generally horizontally disposed structure, a plurality of legs supporting, at their upper ends, the structure, rollers disposed on lower ends of the plurality of legs and adapted to rest upon a floor surface, the rollers allowing the legs, and the structure, to be translated relative to the floor surface, and a pair straps vertically suspended from the structure, the straps adapted to support the users' legs, whereby, the users may place their legs in the straps and perform exercises with the users' arms supported by the floor surface, wherein the users are able to translate their legs relative to their arms as the structure is translated on the floor surface.

A device for suspending gymnastic rings and handles is described. The device has a power spring to automatically retract a strap onto a spool. There is a cam buckle that holds the strap in place at a desired height. There are marks on the strap to use as reference to easily match the rings to the same height. The device is typically used as a pair, one device for each ring. Many handle and bars can be attached.

A portable bodyweight exercise device collapses into a neat and compact folded state. The device is simple to use, relatively inexpensive, and is self-contained and useful in virtually any environment and without need of other materials or conditions. The primary functionalities stem from the device's provision of an elevated weight-bearing anchorage from which to suspend all or part of one's weight, either by direct contact or through connecting equipment such as webbing straps. This allows for a variety of exercises to be performed for every major part of the body and can obviate use of expensive larger home gym equipment or commercial gym membership. In addition to muscle development, the device is favorable to other health and fitness purposes such as physiotherapeutic and palliative care.

Embodiments of the invention provide a safety system for coupling a rider to an amusement attraction with a track assembly including a junction box, and a plurality of control surfaces. The plurality of control surfaces includes slideable and rollable control surfaces. The safety system includes a carriage system for coupling the rider to the track assembly including a main support assembly, and a rolling safety mechanism including a rotatable element. The rotatable element includes a track engagement surface including rolling and sliding surfaces. In some embodiments, the rolling safety mechanism includes a plurality of pucks. Some embodiments include a rolling safety mechanism with a partially truncated ellipsoidal member rotatably mounted to a control support. In other embodiments, the rolling safety mechanism includes two partially truncated ellipsoidal members each positioned at substantially opposite ends of a support frame that includes at least one lanyard support.

A retractable wall mounted exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The retractable wall mounted exercise rack system generally includes one or more brackets attached to a wall, a pair of support members, and a plurality of arms pivotally extending from the brackets and pivotally connecting to the support members. One or more actuators are connected between the brackets and the arms to assist in lifting the structure into a compact retracted position for storage.

A device for performing ankle-based inversion postures. A primary loop in combination with retainer loops forms an ankle enclosure which contracts in response to the application of load tension. An expansion of the ankle enclosure occurs when an upward force is applied to it with a simultaneous application of downward force on the release loop. A linkage between the lowest points on the primary and release loops transfers applied tension between these components to ensure a smooth expansion action of the ankle enclosure. A connector loop forms a topmost location on the device and is the junction point for the mounting loop which anchors the device to support structures for its use.

A robotic sports apparatus includes a plurality of robotic arms and a plurality of fastening members operably coupled to a respective robotic arm of the plurality of robotic arms. Each fastening member is configured for receiving a limb of a patient. Each robotic arm is configured to move each respective fastening member in at least one of a different direction or a different speed relative to one another for opening neural pathways in the patient.
