. . . As the story goes . . . Babe Ruth use to stand next to a tree and swing a heavy axe just like a ball bat.  He would move close to the trunk, as if standing over it like home plate, and then he would back away, taking multiple swings in different locations.  He did this so that he could feel the "Deep Impact" of the axe hitting the tree and thus learn where his point of most power lies. 

The Deep Impact XP Warm-up and Training bat allows for the same concept that Babe Ruth used to determine where he was losing power, and where he was most effectively making contact. 

The Deep Impact XP promotes more practice swings in the on-deck circle!!  The sliding weight on the inside releases at the swings' point of most power.  You know the results of a good or bad swing immediatly!!  By feeling the weight transfer in the bat as the batter takes a full and regular swing, it allows the batter to work on key areas of hitting, such as bat speed, and power points.
