  • Dumbbells have their origins at least as far back as ancient Greece, where a crude dumbbell, the haltere, was used for conditioning as well as for holding in the hands during long jump competitions.
  • the current dumbbell first showed up in the 1600’s, where two equal weights were distributed at the ends of a handle.
  • the dumbbell today is the best-known free weight, used by millions of physical fitness enthusiasts around the world.
  • the dumbbell as it is used today has two equal weights attached to either end of a handle. The user grips the handle and lifts the weight to exercise.
  • the kettlebell has its origins in Russia. Kettlebells were originally used as a weight for field crops, and by the 1900’s the Russian Army was using kettlebells for exercise and conditioning. The kettlebell appears like a cannon ball to which a handle was attached. As opposed to a dumbbell where the weight is evenly balanced on either side of the user’s hand, the kettlebell has the center of weight significantly beyond the hand of user. Thus, while a dumbbell is better for doing curls and other exercises involving and up-and-down movement of the weight, kettlebells are better for swinging exercises and many users feel they provide a better aerobic workout than do dumbbells.
  • kettlebells Over the past several years, interest in kettlebells has increased dramatically, in part because many physical fitness enthusiasts feel that the swinging exercises in which the kettlebell is a superior weight to the dumbbell are more in line with cardiovascular benefits and calisthenics workouts using multiple muscle groups. As such, many gyms, both commercial and those individuals will keep in their homes, have both a dumbbell set and a kettlebell set. This provides a number of problems, including having to purchase and store two sets of weights. From an environmental perspective, a set of dumbbells next to a set of kettlebells represents two separate uses of resources and two sets of pollution from the manufacturing and shipping of each weight set.
  • dumbbells, kettlebells and plates are generally made from cast iron or another heavy metal, it would be desirable to provide a new product that provided the fitness benefits of both dumbbells and kettlebells in a single weight unit.
  • a combination dumbbell/kettlebell in US Patent No. 9,597,543 to Kaszer.
  • this invention does not claim use with a bar, the ability to add additional weights, or provide any protective coating.
  • the protective coating is optional, and intended to be only applied to the silicone wrap that covered the entire BetterBell in one embodiment. It is also contemplated that there may be some “boots” made to slip over the footings of the BetterBell, and could provide a bit of a “protective coating” though, in addition to providing a buffer to contact and make weight identification and branding easier.
  • the current invention provides a solution to these problems by providing a weight that combines a dumbbell and a kettlebell in a single weight that can be used as either a dumbbell or kettlebell, which can also be used in tandem with one unit at the end of a weight-lifting bar. It is contemplated that this can be accomplished either with a hollow center bar, or with holes in the side of the product into which prongs of a weight-lifting bar can be inserted, or a threaded insert cap on the product into which a weight-lifting bar can be screwed.
  • the invention also provides a handle that extends through the weight unit to which additional weights can be attached.
  • the invention comprises a kettlebell with a hole in the center with a handle that a user can grab.
  • the handle is located such that the weight is evenly balanced from side to side, and from front to back, which basically equates to symmetry in shape AND mass/weight across 2 of the XYZ planes... and symmetry in mass across all 3 planes such that it behaves as a dumbbell when grabbed by the central handle.
  • On the other hand because it has the typical kettlebell handle on the top, it can also be used as a kettlebell.
  • An alternative embodiment calls for symmetry in shape AND mass/weight across 2 of the XYZ planes... and symmetry in mass across all 3 planes.
  • a kettlebell could be manufactured with a hollow built into its center through which a rod, similar to the rod holding together two weights to make a dumbbell. It is contemplated the the “handle” could be hollow, and even fitted with threads at either end to allow for the attachment of either lifting rods, or a hexagonal nut that would fit into a hexagonal cavity on the side of the device to allow the hollow handle to be “screwed into place”.
  • a kettlebell could be manufactured with an open bottom portion into which a rod is molded, allowing a user to grab the weight by either the kettlebell top or the dumbbell bottom, or holes in the sides into which prongs of a weight-lifting bar can be inserted.
  • the rod could extend through the sides, and additional weights could be placed on the ends of the rods.
  • additional weights could be placed on the ends of the rods.
  • One embodiment calls for the adjustable weight BetterBell to have no rod that extends outside the shell body.
  • the top of the invention could have a threaded receptacle into which one end of a weight-lifting bar could be inserted, such that one invention could be attached to either end of the weight-lifting bar.
  • the current invention provides a solution to the problem of having to manufacture, ship, and store a set of dumbbells and a set of kettlebells and multiple plate attachments components by having a multi-function bell with a cavity in its center with a handle that can be gripped like the handle on a dumbbell, gripped on the top handle like a kettlebell and used as a variable weight component on a bar like a plate.

  • Another object of the invention is to provide a device that can be attached to the end of a weight-lifting bar such that two of the inventions on opposite ends of the bar can allow for a traditional weight-lifting bar type of workout.
  • Another object of the invention is to provide a device that has four holes in the side portions that would allow for a weight-lifting bar with two “prongs” at either end to skewer one of the devices on either end of the bar, including a version where the bar would be a different “end” shape with the 2 prongs instead of the standard bar end.

  • the dumbbell handle is located such that the kettlebell top hemisphere - defined as that portion of the kettlebell above the dumbbell handle - may be equal in weight to the kettlebell bottom hemisphere - defined as that portion of the kettlebell below the dumbbell handle. Because the kettlebell body and the cavity are symmetrical, the right-side hemisphere - defined as that portion of the kettlebell to the right of the center of the dumbbell handle - is equal in weight to the left side hemisphere, -- defined as that portion of the kettlebell to the left of the center of the dumbbell handle, are equal in weight.
  • the kettlebell handle is attached to a kettlebell body, allowing a user to swing the kettlebell in a traditional manner.
  • the kettlebell bottom is flattened and allows the invention to rest on the ground in a secure manner.
  • the kettlebell body has a cavity, in which a dumbbell handle is location. The user can, as an alternative to grabbing the kettlebell handle and using the invention like a traditional kettlebell, grip the dumbbell handle and use the invention like a traditional dumbbell.
  • the portions of the cavity above and below the dumbbell handle are large enough to accommodate the hand of an average adult.
  • the kettlebell body still has a kettlebell handle which allows the invention to be used in a traditional manner, but the cavity in this case is an open cavity in the bottom portion of the kettlebell.
  • the open cavity in this case extends from the kettlebell bottom 6, which in that case comprises two flattened ridges extending parallel to the cavity on either side of the open cavity.

  • BetterBell 3.0 provides an ability to use a bar to link 2 or more BetterBells together. It is also contemplated that a single device could be attached to the end of a far, thereby creating a long bar with a heavy object at the end.
  • the top handle makes an easy grip to help slide the BetterBells on and off a bar. helps line up the holes with the bar with one hand... vs plates typically need 2 hands.
  • the bar allows a user to perform exercises that link 2 or more BetterBells together... effectively adding weight as well as new movement patterns.
  • Bench Press deadlift, squats. These exercises can be performed with just 1 BetterBell but using a bar helps to link the mechanics to both sides of the body simultaneously.
