The rotator cuff exercise device includes a ring unit, a mounting board, and a pair of mounting tracks. The rotator cuff exercise device may be adapted to exercise joints and muscles or may prevent the loss of flexibility in an elbow or a shoulder blade. The rotator cuff exercise device may be particularly suited for therapy after an injury involving a rotator cuff. A handle may detachably couple to an individual rotatable ring selected from one or more rotatable rings of the ring unit and may be adapted to be grasped by a hand of the user. The handle may be operable to move the individual rotatable ring in a circular motion. The circular motion of the handle may exercise the joints and muscles of the user.

A shoulder motion exercise device, kit, and method of use having a retainer, a plurality of connectors, an extender, and a slider. The device aids in the stretching and exercise of at least a shoulder and a portion of the torso.

A device for training and rehabilitation of a limb is provided. The device provides a board with an ability to magnetically levitate a movement base above the board to allow for controlled movement of a limb or other body part of a user needing training and rehabilitation in various directions.

A shoulder motion exercise device and method of use having a retainer, a connector, an extender, and a slider. When the user mimics a golf swing, the device aids in the stretching and exercise of at least a shoulder and a portion of the torso.

A resistance training device for hands-free exercising of the back and shoulders includes a frame. A bench is coupled to the frame and is configured to seat a user. A backrest is coupled to the frame proximate to a rear edge of the bench. A pair of arms is pivotally coupled singly to opposing side supports of the frame. A resistor is operationally coupled to the pair of arms. The arms are positioned on the frame such that the arms are configured to abut elbows of the user seated on the bench. The resistor is positioned to resist the user's effort to pivot the arms relative to the frame, thus exercising the back and shoulders of the user without use of the user's hands.

Apparatuses, systems, and methods of use are disclosed for enhancing upper body exercise. An apparatus includes a domed hand support section, the domed hand support section having a plurality of recesses configured to receive a palm, thumb, and fingers of a user's hand while the user's hand is held in a naturally curved open-position. The apparatus also includes a surface engagement section secured to an underside of the domed hand support section and configured to engage a supporting surface. When the surface engagement section is deployed on the supporting surface and the palm, thumb, and fingers of the user's hand are placed in the plurality recesses on the domed hand support section, the domed face supports the user's hand in the naturally curved open position while the user exerts force against the domed hand support section and that is at least partially directed toward the supporting surface.

A pulley system of an exercise device for suspended weight training includes a first block with a first pulley, a second pulley, and a first attachment point. A second block is removably coupled to a weight and includes a third pulley and a second attachment point. A grip is configured to be held by a user while exercising and has a third attachment point. A line having a first line end is fixedly coupled to the grip and a second line end fixedly is coupled to a connection element. The connection element is configured to be selectively coupled to each of the first attachment point, the second attachment point, and the third attachment point, permits a user to reduce an effective amount of the weight lifted by the user with movement of the grip to a pre-selected fraction of the weight.

Various hand-held exercise weights are configured to fit comfortably in a person's hand. Some embodiments define a circular loop about a central opening. Some embodiments have first and second segments that change in girth as a function of distance from a juncture defined therebetween. Some of the embodiments have handgrips of different shapes.

A method for controlling exercise load variations in a strength exercise machine, includes, at a current time instant t.sub.i, detecting an exercise position within a set range of motion of a user, and checking if a previously set trigger condition of an exercise load variation includes the detected exercise position of the user within the set range of motion. If a previously set trigger condition of an exercise load variation includes the detected exercise position of the user within a respective range of motion, the method includes setting a trigger condition of an exercise load variation as the current trigger condition of exercise load variation having a first speed threshold for execution of motion by the user, and reducing an exercise load based on a comparison of speed for execution of motion by the user and the first speed threshold.
