Purpose:
Players learn and practice what the back arm does during a swing.
Setup:
The player kneels at the side of a tee.

Instructions:
1. The batter gets down on her back knee and swings the bat and hits the ball off the tee using just her back arm.
Coaching Tips:
- When using the back arm, it’s important for the batter to keep a firm wrist and arm to keep the barrel higher than the hands as it comes through the contact area.
- On the swing, the batter should come down through the ball instead of dropping the bat first and then coming forward on a level plane.
- Raise the tee higher to test the batter’s wrist strength.
- With the one-arm drills, it is best to use a youth (16- or 17-ounce) bat.
For Younger Athletes:
- Start with the fundamentals of the back arm swing, focusing on mastering the basic movement before adding power.
- Incorporate exercises to improve grip strength, as a strong grip is crucial for controlling the bat with one arm.
- Use positive reinforcement, acknowledging efforts and progress to build confidence and encourage development.
For Older Athletes:
- Introduce advanced techniques like adjusting the swing based on pitch location, helping develop a more versatile hitting approach.
- Challenge with heavier bats in the drill, if comfortably manageable, to help develop greater wrist and arm strength.
- Utilize video analysis for feedback, allowing older players to visually understand and correct their mechanics more effectively.
