This drill is a great way maximize power in a batters swing
This drill requires a punching bag (about $45 dollars at any sporting goods store) and somewhere to hang it.
Batters will take their stance with the punching bag slightly in line with the batters front foot.
The batter will swing, make contact with the bag, and then proceed to follow through with their extension pushing the bag.
The batter can adjust where she stands and makes contact with the bag depending on what pitch she would like to work on.
