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.

An exercise tool 1 for improving oral function inserted and used in an oral cavity includes: a base 10 inserted in the oral cavity; and a hollow bulge 20 which is made of an elastic body and protrudes from the base 10. Level difference portions 41-43 and 51-53 are provided in a vertically intermediate region of at least one of an outer surface and an inner surface of the bulge 20.

A training device includes a tether having inelastic portions disposed between its ends, where each inelastic portion is separated by an elastic portion, and where each of the ends is configured for engagement with hands of a trainer. The training device may include a belt that wraps around an athlete's body including a ring on a back portion thereof having an opening for receiving an end of the tether therethrough. When the belt is secured around the athlete's body and the tether is disposed through the ring, the training device may create a coupling between the trainer and athlete when the trainer secures the ends of the tether. The coupling may be substantially released when the first user releases one end of the tether such that the released end is substantially unrestrained to traverse through the ring thereby fully disengaging the tether from the belt.

Muscle contraction device including: a frame intended to be wedged between a floor surface (30) and an upper structure (29) of a room, the frame including a structure bar forming a circular arc, an upper element attached to a first end of the structure bar and a lower element attached to a second end of the structure bar both intended to cooperate with the upper structure of the room and the floor surface, respectively, a feedback element attached to the frame, a loading element coupled to the feedback element adapted to be pulled by a user (27) toward the inside of the circular arc of the structure bar and to exert on the loading element a feedback force opposing the pulling force of the user.

A practice device for simulating a cheerleading stunt includes a frame that has a base plate and a top plate; a tubular shaft that extends between the base and top plates; a weight that is disposed in the tubular shaft; a spring that is disposed in the tubular shaft and that contacts and biases the weight; a shoe structure; and a mount that supports the shoe structure at one end thereof and that is constructed and arranged to be disposed within the tubular shaft with the spring disposed between the weight and the mount.

A shoulder motion exercise device and method of use having a retainer, a connector, an extender, and a slider. The extender is gripped in one hand, the slider, which is in slidable engagement with the extender, is held in the other, and the slider is attached to the retainer at, or above, the elbow of an intended user. 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.
