In which sport is the Wooden Dummy used?

When in doubt use process of elimination. Even if you didn't know the answer right away you would determine that the object in the photo had no realistic use in the other sports

I couldn't figure this out from the photo and description, so I looked it up. The dummy is human size. Although the "arms" and "leg" are stationary, they represent an attacker's limbs in motion. The student practices blocking the attack safely, i.e., without breaking their own bones.

I REMEMBER BRUCE LEE DOING THIS IN ONE OF HIS MOVIES.
