How would you take a pov video like this without attaching the camera to your body?

I'm watching this video: https://youtu.be/2VujUm6K-IU

At times he is working with his hands with the camera directly on front of him while using both hands to work. The camera never moves or gets bumped. In one shot he is hitting something with a hammer. Is he just hugging a tripod carefully? Using a boom? I'm scratching my head.
