A apparatus or system defined by a handheld exercise device that includes a weighted body; a handle arranged along a radial axis of the weighted body; and a connector that creates at least one connection between each radially distal end of the handle and a component of the weighted body. The handheld exercise device, in use, minimizes one or more peak forces and rotational inertia acting on a forearm of a user actively engaging the handheld exercise device in motion.

A jump rope device includes a connection assembly having a male connecting member and a female connecting member. The male connecting member includes a head having first and second locking projections. The female connecting member defines an opening configured to receive at least a portion of the male connecting member into an internal cavity. The female connecting member includes first and second locking arms that are biased into a first position, and configured to move from the first position into a second position when the male connecting member is inserted into the opening. Rotation of the male connecting member relative to the female connecting member moves the locking projections out of contact with the locking arms and into respective apertures defined in the female connecting member, allowing the locking arms to return to the first position and creating a secure connection between the male and female connecting members.

A hand held workout bar with rotating decagon shaped weights that have cutouts to affect weight distribution.

An apparatus and method for exercising with a child attached to the legs is disclosed. An example embodiment includes: a child wrap element having a portion that can be wrapped around and secure a child; a leg wrap portion having at least one loop that can be secured to the legs of a user; and a connecting portion integrated between the child wrap portion and the leg wrap portion.

A device to strengthen a person's arm muscles through the utilization of a portable device including a handle portion and a weight component with the two components separated by a flexible rod is provided. Such a device allows for the user to grip the handle portion and act as if they are throwing such a handle portion while the weight end moves along an arc defined through the length of the flexible rod. The resultant action is the generation of centripetal force along the defined arc with the reactive centrifugal force providing resistance to the user's arm muscles in a manner that is unique and heretofore unattainable through the utilization of a portable exercise device. The flexible rod component provides at least 1 foot (100 cm) of spacing between the handle portion and the weight portion.

A device and method for influencing the movement and muscular function in the neck, includes a helmet, the helmet has a rim, said rim has notches along the edge, on top of the helmet there is attached a vertical rod, on top of this vertical rod there is attached at least two laser sights pointing forward, at least one rod is attached at one end to the vertical rod, and the at least one rod can rotate around the vertical rod.

A pronation supination wrist deviator exercise device includes a handle having a proximal portion and a distal portion; a shaft defining a longitudinal axis extending from a proximal end to a distal end; and a head portion having a predetermined weight. The head portion or the handle are mounted for relative movement on the shaft between a first position and a second position. The head portion and the handle define a first distance. The predetermined weight of the head portion represents a first weight. The first weight multiplied by the first distance represents a first effective torque of the device. When the distance between the head portion and the distal portion of the handle is changed to at least a second distance, the first weight multiplied by the second distance represents at least a second effective torque of the device.

Training neck muscles in such a way as to improve responsiveness to head acceleration forces, and to help prevent concussion and/or screening subjects who are at high risk of concussion, especially from contact sports or military activities, may be accomplished by a device and/or method of training that incorporates an adjustable centripetal force about a fixed axis on the head. The centripetal force may be adjusted through varying the weight and/or length of a force arm, and neck muscle performance may be measured by a number of revolutions of the force arm completed over a set time period or a time required to complete a pre-determined number of revolutions of the force arm.

The present invention relates to a device for exercising the pelvic floor muscles in women, which comprises a main component (A), a secondary component (B) and a set of external weights (P). Component (A) is directly related to pelvic floor muscle contraction exercise. Component (B) allows the evaluation and monitoring of contraction exercises by measuring the displacement of a rod on a graduated ruler. The set of weights (P), with different loads, allows it to impose resistance of different magnitudes on the muscle exercises to be performed, according to the user's needs and objectives. Thus, this invention falls within the technical field of mechanical functioning devices, with application to the medical area, for the treatment and/or prevention of pathological situations related to the alteration of the muscular function of the pelvic floor region.

A centrifugal exercise device for performing rotator cuff exercises. The device comprises a hand grip, a freely rotating pivot shaft extending from the upper end of the grip, and a flexible, semi-rigid cable extending through an intermediate portion of the pivot shaft at a location spaced longitudinally from the upper end of the grip. A shorter inner terminal portion of the cable extends from one side of the pivot shaft, while a longer weighted portion of the cable extends from the other side of the pivot shaft with a weighted member secured to its end.
