Abstract: A training aid for baseball hitters to assist in keeping a batter's lead arm flexed in a proper hitting stance. The training aid has a first cuff which attaches to the batter's forearm. A second cuff is attached to the batter's upper arm and one or more elastic straps are connected between the two cuffs.

Abstract: A practice bat for improving the swing of a bat used in a game such as baseball. The bat is hollow and has a moveable weight which moves between the handle end and the striking end of the bat. The weight may be held in the handle end by the squeezing of the top hand of the user's grip and, thus, is not properly released. In a relaxed grip, however, the swing of the bat causes the weight to move outwardly to strike the striking end of the bat. Preferably, the weight is held by making a portion of the handle end of the bat deformable so that it can be moved to press against the weight and hold it at the handle end.

Abstract: An improved baseball batting practice device of the type having a baseball suspended from a stationary arm on a flexible line. The device has a tethered baseball held by a generally horizontal arm which is supported above the ground by a vertical support arm affixed to a ground arm resting on the ground which, in turn, is affixed at right angles to a longitudinal support bar. A back foot rest bar is adjustably affixed to the longitudinal support bar so that the hitter can place his back foot at a predetermined distance from the tethered bar while hitting the tethered ball. The foot rest bar may be placed on either side of the ball so that both right-handed and left-handed hitters can use the device.
