An exercise apparatus is described. The apparatus includes a body having a first end disposed opposite a second end. The body also includes a first side disposed opposite a second side and a third side disposed opposite a fourth side. The first side includes a first hand grip and the second side includes a second hand grip. The body includes one or more receiving portions configured to receive one or more weights therein. The body has a hollow interior. In some examples, the hollow interior is divided into two hollow interior portions.

A user-assembled free weight includes a container made of a contiguous material and having at least one cavity. A heavy curable fill material is placed inside the at least one cavity. Together the heavy curable fill material and the container produce at least a target weight and the heavy curable fill material is non-removable from the container.

The disclosure provides an exercise device comprising a weighted head and handle to simulate swinging a sledgehammer without causing the damage typically resulting from a sledgehammer having a solid head or hammer portion attached to a handle. Some embodiments provide quick release connectors between the weighted head and the handle. Methods for producing and using the weighted head and handle are also disclosed.

A method of producing an exercise weight structure comprises mixing a particulate material with a binder material and molding the resulting mixture to an appropriate shape. An outer skin for the exercise weight structure is firstly formed of a resilient material, and forms a mold into which an inner weight section or body is molded or cast. The inner weight section and the outer skin are both formed of recycled material and include a common binder material.

In some embodiments, a heavyweight jacket includes a main body configured to fit on the torso of a wearer and sleeves that are fully detached from the main body. The sleeves advantageously facilitate putting on the heavy jacket, while providing a jacket of high weight. To form the heavyweight jacket, a pre-bonded fabric may be used. The fabric is pre-bonded and may optionally be further layered to increase the garment's weight without sacrificing flexibility or breathability. The layered fabric distributes the garment's weight evenly and ensures that the garment does not excessively restrict a wearer's freedom of movement or cause the wearer to overheat. The weight of the fabric may be increased by using a heavyweight glue to bond various layers of material together.

Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

Embodiments of the present invention are directed towards a tubular exercise device for performing loaded movement training exercises and a method of manufacturing the device. In embodiments, the device may comprise a substantially cylindrical, tubular body have flared ends that extend radially outward from the longitudinal axis providing added grip versatility and various structural benefits. In embodiments, the device may comprise one or more apertures have sides with curved indentations that are suitably shaped to facilitate the entry of one or more hands into the apertures and to increase the versatility of gripping positions. The device may comprise a thermoplastic elastomer for its rigidity and structural stability. In further embodiments, the exterior surface of the body may be textured to facilitate gripping the exterior of the surface. In embodiments, the device may comprise one or more interior ribs that provide desirable inertial properties to the device for performing various exercises.

An improved dumbbell free weight is discussed, which includes one or more base weights, the dumbbell further having a pair of second, upper weights positioned above where the upper weights are suspended by upper braces extending from a handle attached to the one or more base weights.

A muscle activating and exercising device and a method of activating and exercising muscles of the human body. The device includes an outer material and at least one flexible inner material. The device is an elongated device that is pliable enough to be wrapped around an object. The device also has an outer surface that creates a frictional fit between the device and the wrapped object. The wrapped object could be, for example, a wrist or ankle on a human limb or a location on a portion of sports equipment (e.g., a lacrosse stick, baseball bat, hockey stick, golf club or tennis racket). The method includes a method of activating muscles using the device. Through such a method, a user can, for example, build muscle strength and/or reduce muscle tremors.
