Beginning Kung Fu

My grandson has never met a stick that couldn't be used as a sword. He also likes to do round house kicks and make kung fu  motions with his arms. His mom has gotten him involved in kung fu lessions. The person who teaches the lessions has agreed to let him do this even though he is only 3 1/2 years old because of his level of coordination and strength. This should be really good for him especially to become more focused.
