Baton impact weapons training is an optional part of Frisee that much. Baton training can help to develop upper body speed and power. It will help with throwing sports and batting sports too.
Here's a Youtube video showing me striking a martial arts shield using my polypropylene batons.
I struck the shield 11 times in a row with each one of my batons. I viewed the video in slow motion in order to count the strikes. You're welcome to do the same if you're curious.
