10. The adjustable kettlebell device according to claim 1, further comprising at least one quick release clamp secured to at least one of the post and the sleeve to prevent vertical movement of at least one of the standard and Olympic weight plates along an elongate length of the post.
11. The adjustable kettlebell device according to claim 1, further comprising at least one additional handle of a different size or shape than the handle, configured to adapt the adjustable kettlebell device to a different user's hand size.
12. The adjustable kettlebell device according to claim 1, further comprising a coating applied to at least one component of the adjustable kettlebell device.
13. The adjustable kettlebell device according to claim 12, wherein the coating is applied as one of a paint and a powder.
14. The adjustable kettlebell device according to claim 1, wherein the base has a form of a spherical frustum.
15. The adjustable kettlebell device according to claim 1, wherein the base has a form of a cylinder having a transverse dimension and a thickness wherein the transverse dimension is larger than the thickness, the cylinder having an outer edge, the outer edge having an upper portion that is curved inwardly.
16. The adjustable kettlebell device according to claim 1 wherein the stop mechanism comprises a ledge formed by a transverse dimension of the bottom portion of the post being greater than a transverse dimension of the upper portion of the post such that the ledge defines the stop mechanism.
17. The adjustable kettlebell device according to claim 2, wherein the pin is angled such that a longitudinal central axis of the pin forms an angle between opposite ends of the pin.
18. The adjustable kettlebell device according to claim 1, wherein the Olympic weight plate has an aperture through which the sleeve slidingly receives the Olympic weight plate, the Olympic weight plate having an outwardly extending opening in addition to the aperture, the outwardly extending opening extending through a thickness of the Olympic weight plate.
19. The adjustable kettlebell device according to claim 1, wherein the post is unitary.

Description

ADJUSTABLE KETTLEBELL DEVICE CROSS-REFERENCE TO RELATED APPLICATION [0001] The present application claims priority under 35 USC 119(e) to U.S. Non-Provisional Patent Application No. 18/219,726 filed on July 10, 2023, the contents of all of which are incorporated herein by reference in their entireties. BACKGROUND Statement of the Technical Field [0002] The present disclosure relates generally to exercise devices. More particularly, the present disclosure relates to adjustable kettlebell devices. Description of the Related Art [0003] The traditional kettlebell is a cast-iron or cast steel weight (resembling a cannonball with a handle) used to perform all types of exercises, including but not limited to ballistic exercises that combine cardiovascular, strength and flexibility training. The Russian kettlebell was a type of metal weight, primarily used to weigh crops, in the 18th century. Kettlebells began to be used for recreational and competition strength athletics in Russia and Europe in the late 19th century with the birth of competitive kettlebell lifting dating back to 1885. The use of kettlebells in exercise programs in the USA and Western Europe is a relatively recent phenomenon but has quickly gained momentum in recent years as evidenced by the increased use in home gyms as well as public gyms and athletic clubs. This is understandable because, by their nature, typical kettlebell exercises build strength and endurance, particularly in the lower back, legs, and shoulders, and increase grip strength. The basic movements, such as the swing, snatch, and the clean and jerk, engage the entire body at once, and in a way that mimics real world activities. Furthermore, research has demonstrated not only that the unique biomechanics of certain kettlebell exercises transfers well to certain key sporting movements but that, in general, the potential power and strength benefits of kettle bell training provide a viable alternative to traditional resistance training methods. In addition, kettlebells are now widely used not only in numerous types on anaerobic exercise but also in many types of aerobic exercise. Studies have shown that kettlebells are not only beneficial in when used in ballistic and anaerobic activity but can be very effectively used as a complementary or alternative mode of improving cardiovascular fitness. Furthermore, studies also show that kettlebells can play an important role in the domain of physical therapy and rehabilitation. [0004] The typical traditional kettlebell is a non-adjustable, cast iron weight which requires the purchase of a set of kettle bells in order to allow for the performance of different types of exercises and/or to vary the amount of weight used depending on the exercise and the strength of the user. This can be very expensive with the cost of a full set of kettle bells ranging from, for example, $1000 to over $2,000. In addition to the considerable expense, a full set of kettlebells requires a significant amount of space for storage. SUMMARY [0005] The present disclosure concerns implementing systems and methods for using an adjustable kettlebell device. The methods comprise: decoupling a handle from a post having a first outer diameter that allows the adjustable kettlebell device to be compatible with a first weight plate of a first type; sliding the first weight plate on the post; coupling the handle to the post so that the first weight plate is retained on the post and is movable in unison with the handle, post and base; using the post to prevent horizontal movement of the first weight plate relative to the base and handle when the adjustable kettlebell device is being held by a user for exercise purposes during a first time period; decoupling the handle once again from the post; removing the first weight plate from the post; sliding a sleeve over the post (where the sleeve has a second outer diameter that allows the adjustable kettlebell device to be compatible with a second weight plate of a second type different from the first type); sliding the second weight plate on the sleeve; coupling the handle to the post once again so that the second weight plate is retained on the sleeve and is movable in unison with the handle, post and base; and using the sleeve to prevent horizontal movement of the second weight plate relative to the base and handle when the adjustable kettlebell device is being held by the user for exercise purposes during a second time period. [0006] The methods may also comprise: using the post or sleeve to structurally support the handle and maintain the handle's position relative to the base; using the post or sleeve to limit a distance in which the handle can travel along the post towards the base; optionally securing a pin or clamp (or other securing mechanism) through or around the post above the handle to prevent vertical movement away from the base; securing a clamp (or other securing mechanism) to the post below the handle so as to prevent
