Use the Arm Strong anywhere.
Along with this device you will get an indoor quick clip, the “Throw Like The Pros” instructional booklet, a sport travel bag and an instructional DVD.



My daughter also used this when she was younger, and I really think it did a great job of building up her arm strength. She was a catcher. and really could fire the ball.. The main thing is they must be dedicated enough to use it on a regular basis.
