An adjustable kettlebell device comprising a solid right circular frustum as a base, a post, a sleeve, one or more weight plates, one or more quick release clamps, and a removable handle. The post has an outer diameter compatible with standard weights, and a sleeve that slides over the post has an outer diameter compatible with Olympic weights. The handle is configured to facilitate an addition/removal of the weight plates, and may be swapped with different sized handles for use with different sized hands.

A fitness slider is provided that is capable of holding a weight plate during use, to be manipulated by one or more extremities using the weight plate as the engagement surface for the user's hand or foot. Another fitness slider is configured to mate with different sizes of weight plates. Yet another fitness slider is provided that includes a handle on top of the weight plate as the engagement surface.

An exercise roller includes an elongated bar having grip handles arranged at opposing axial ends of the elongated bar, a cylindrical core supported by the elongated bar between the grip handles, and a cover that surrounds the cylindrical core and is formed of a material having a repeating pattern.

Multiple embodiments of a portable, handheld exercise device comprise a spherical outer shell with multiple parallel handles on the outer surface thereof containing a rotating mass therein. An inner shell is spaced from but attached the outer shell. A gyroscopic energy-generating structure (GEGS) is within the inner shell. The GEGS comprises a rotating disc or a rotating mass simulating a rotating disc. The rotating disc or a mass is powered to spin around an axis orientated in a preselected orientation to the multiple parallel handles. When the one or more handles are held by an individual the spinning characteristics of the rotating disc or mass creates a force against the user's hands. An internal or external controller allows the user to vary the spinning characteristics of the spinning mass and the level and intensity of the resultant exercise provided to the user in counteracting the forces created.

“Abstract Balls” is a new product that allow an individual to engage in an effective abdominal workout while walking or running. A fitness enthusiast would simply grasp the balls on the ends of the bar and walk or run in the conventional manner. While holding the unit, the person's arms would move from side to side, opposed to moving back and forth alongside his body. This would cause him to turn his or her abdomen and torso slightly to the left and right, which would isolate and target the muscles in the abdominal region and core. Of course, since the user would be walking or running while using the “Abdomen Balls” his or her heart, metabolic, and circulation rates would all increase, which would help him or her burn calories. Of course, using “Abdomen Balls” as part of a consistent fitness regimen would help an individual develop a slimmer abdominal region and lose weight. This could lead to lower cholesterol levels, lower blood pressure, and a healthier overall lifestyle. It would also result in a more defined abdominal region. In turn, this would result in a more attractive appearance, which improves and individual's self-esteem and overall outlook on life. Since “Abdomen Balls” would help improve abdominal/core strength, it would also improve performance in a wide range of sports and fitness activities. In addition, “Abdomen Balls” would be easy to use and ideal for individuals who were just beginning a fitness program. It would allow individuals to begin exercising at a slow pace, which would not only allow for consistent results when starting a fitness program but would also prevent injuries that could slow an individuals's progress and discourage him or her from continuing an exercise program. Such a product would also eliminate the need for an individual to perform abdominal exercises such as sit-ups and crunches. This would prevent stress and strain on the lower back, which would enhance comfort and could prevent injuries.

The present invention provides an exercise device (100) for exercising core muscles of a user’s torso. The exercise device comprises a frame (110), configured to be supported by the user and a radially outwardly facing channel (130; FIG. 6), the channel (130) configured to receive a resistance member. The frame defines an aperture (112) configured to receive a torso of the user and the device (100) is configured to provide a resistance force against which the user can exercise when the device (100) is in use. Also claimed is a kit of parts comprising the device (100) and a resistance member, and a method of exercising core muscles of one’s torso.

The device as disclosed herein is simple and easy to use, and inexpensive to produce. It provides a good calf workout from home for the calf and lower leg. It comprises a foot baseplate having a lower curved surface or frame, a series of straps to attach the user's foot to the baseplate and an attachment point for a resistance band.

An arm extension apparatus comprising a propulsion blade comprising a top half and a bottom half, wherein the top half is generally straight and wherein the bottom half comprises a curve, and wherein the bottom half comprises a proximal end and a distal end, and wherein the distal end comprises a foot, and wherein the foot comprises two split toes.

A leg muscle, abdominal muscle, and spinal exercise device adapted for imparting curvature to a lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force includes a frame for placement on a floor. The frame has a top surface and a bottom surface, wherein the top surface and bottom surface are in a spaced apart relationship forming a hollow portion there between. At least one inflatable bladder is carried by the top surface of the frame. A body strap attachment passes through the frame in non-fixed relationship and is partially disposed within the hollow portion for encompassing the user's thoracic-sacral spinal region and securing said frame. An elongate stirrup strap member is attachable to the body strap attachment thereby connecting to the user's spinal region. A stirrup is attachable to the stirrup strap member distal end.

An abdominal exercise roller with a powered wheel mechanism to assist the user during the abdominal exercise routine. The invention includes utilizing sensing technology and the electronic module to control the motor and optimize the performance of the abdominal roller during the exercise routine.
