In the video, a man is seen in a gym, wearing a green shirt and a black cap. He is holding a large knife in his hand and appears to be demonstrating how to use it. The man is speaking to the camera, presumably explaining the proper way to handle the knife. The gym is equipped with various exercise machines and equipment, and the man is standing in front of one of them. The lighting in the gym is bright, and the man's movements are deliberate and controlled as he handles the knife.
