Watch as Coach explains, and slappers demonstrate the Bosu Balance Drill. This is a progression drill that incorporates the swing, walkthrough, and running to 1st base. The slapper will get into their crossover position and use the Bosu Ball for balance as they take a swing off the tee, holding the position for a second. It is important that the crossover foot is directionally in the proper position. All slappers are different so make sure they are in a comfortable spot when doing this drill.
