A baseball practice bat having a main bat barrel, a movable handle portion, a fixed handle portion, a shaft running through the handle sections. The shaft may also run through the bat barrel. When properly aligned, a projection on one of the handles impacts the other handle, thereby creating a sharp crack, indicating that the practice swing was good. If the handles are not properly aligned, instead a soft thud is created indicated that the practice swing was not properly executed. The handles take the form of tubes surrounded by resilient grips. In one embodiment, a post extends from the movable handle and a resilient washer with a cut-away portion is located at the top of the fixed handle. When the handles are properly aligned, the post can impact the tube portion exposed by the cut-away portion of the washer. In another embodiment, projections extend from the tubes of the fixed handle and movable handle. When the handles are properly aligned, the two projections impact, creating the sharp crack.
