Disclosed herein are training devices having at least two elastic members connected to a respective end of an inelastic member. The training devices first and second handles coupled to a respective one of the two elastic members. The training devices may be used to add various strength training modalities to a cardiovascular workout or fitness regimen. The training device may be provided in the form of a kit including elastic and inelastic members having differing elasticities, lengths, and widths and including removable handles, potentially of differing types.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A headgear for neck rehabilitation and weight training includes first and second straps forming a loop for wrapping a forehead of a user, an upper strap device abutting a top of a head of the user, and a lower strap abutting a chin of the user. The second strap is coupled to the first strap and is adjustable in length to fit the head circumference of the user. The upper strap device is adjustable in length to fit the spacing between the forehead and the top of the head of the user. The lower strap is coupled to the loop formed by the first and second straps and is adjustable in length to fit the chin of the user. The headgear can be assembled with one of two rehabilitation accessories in a rehabilitation mode or assembled with a weight training accessory in a weight training mode.

The exercising device preferably has a handle with a proximal end and a distal end and a swing arm having a first end and a second end. The proximal end of the handle is rotatably connected to the first end of the swing arm, allowing the swing arm to rotate around the proximal end of the handle in a “clock-hand” fashion. A connecting shaft and swing arm stopper prevent the swing arm and handle from becoming separated during use. The exercising device may further have a weight member positioned in a weight member recess located close to the second end of the swing arm. The weight member increases the difficulty of using the exercise device and is removably attached to the swing arm. A safety sleeve can fit over the weight member recess to prevent the weight member from dislodging during use.

An exercise equipment configured to exercise muscles by require the muscles to generate torque intermittently is provided. The exercise equipment includes a sleeve. A pipe is slidably disposed within the sleeve. The sleeve is concentric to the pipe wherein the outer surface of the pipe is spaced apart the inner surface of the sleeve. A counterweight is mounted to at least one end of the pipe wherein the rotation of the pipe along an orbital path causes the pipe to turn within the bore of the sleeve. The turning of the pipe is a result of the counterweights completing a revolution as the counterweights rotate about the longitudinal axis of the pipe. The turning of the pipe generates a pulse so as to actuate muscular structure within the body of the user.

An adjustable sledgehammer workout apparatus may include a handle, a pair of supporting brackets connected to the handle, and a clamping assembly connected to the supporting brackets. The supporting brackets may be rectangular in shape with beveled or rounded edges. The clamping assembly may include a pair of lower c-shaped portions connected to a pair of upper c-shaped portions using a hinge assembly. Different size and weight dumbbells may be connected to the handle using the clamping assembly.

An exercise and massage device utilizes a substantially spherical body having a central cavity that extends to opposite sides of the spherical body so that the cavity forms openings on opposite sides of the spherical body. A transverse handle is positioned within the cavity that extends across the cavity. At least one grasping portion is located within the cavity and is spaced between the transverse handle and at least one of the openings of the central cavity to provide a fingerhold during use. A resilient outer layer surrounds the spherical body and provides an exterior surface of the spherical body. The resilient outer layer is provided with projections to facilitate massage when used in the massage mode when the device is used in a massage mode. The device is weighted to provide a total weight of from 2 lbs or more. In another embodiments of an exercise and massage device at least one ring member is encased within the spherical body to provide at least one of weight and structural support to the device.

An exercise and massage device utilizes a substantially spherical body having a central cavity that extends to opposite sides of the spherical body so that the cavity forms openings on opposite sides of the spherical body. The spherical body has an outer core of a first resilient hardness. A single rigid handle is positioned within the cavity. The openings of the cavity are sized and configured for allowing a user to access and manually grasp the handle through either opening. A resilient outer layer surrounds the outer core of the spherical body and provides an exterior surface of the spherical body. The resilient outer layer has a second resilient hardness that is less than that of the first resilient hardness of the outer core of the spherical body to provide a cushioning effect when the device is used in a massage mode. The device is weighted to provide a total weight of the device of from 2 lbs or more.

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.
