BACKGROUND
It has been said the act of striking a pitched spherical baseball with a cylindrical bat is one of the most challenging feats in all of sport. Typically, pitchers at the professional and collegiate level are capable of throwing a baseball in excess of 90 miles per hour (1594 inches per second). As such, a baseball thrown at 95 mph reaches home plate in 0.4 seconds, and will traverse home plate in approximately 1/100th of a second. Further, many pitchers are capable throwing a baseball with various rotations, thereby changing the flight characteristics of the thrown ball. As such, a batter must first determine what type of pitch was thrown, extrapolate the ball location when crossing home plate, and initiate swinging the bat on an intersecting plane with the thrown ball. Further, the batter must strike the thrown ball with the bat with sufficient force to drive the ball into playing field. Ideally, the ball will be struck with sufficient force to render to the ball unplayable, thereby resulting in a home run. It has been shown that the speed at which the batter can swing the bat greatly affects the batter's likelihood of success. More specifically, the greater the speed at which the batter can swing the bat the more likely the batter will succeed in striking and driving the thrown ball.
In the past, a number of devices and techniques have been employed to increase the bat speed of a batter. For example, weighted rings referred to as “doughnuts” may be positioned on the barrel of the bat to assist a batter in warming up before entry into the batter's box. While these devices have proven somewhat successful in increasing the weight of the bat prior to use, a number of shortcomings have been identified. For example, the weighted ring must be removed from the bat prior to striking the ball. Further, the addition of the weighted ring drastically alters the balance characteristics of the bat, which may result in unwanted variations in the batter's swing. Lastly, at times the batter may wish to practice his swing using a lighter bat than he would otherwise use.
Thus, in light of the foregoing, there is an ongoing need for an adjustably weighted training device permitting a hitter to practice his/her swing when striking a ball.
SUMMARY

More specifically, the present application discloses an adjustably weighted training device permitting a user to easily increase or decrease the weight of a bat, thereby permitting the user to selectively increase or decease the speed at which he/she swing the bat. Further, unlike prior art devices, the device disclosed in the present application
