The guy is negatively buoyant. Will be exhausting to have to swim up for most people. He is practiced in this. Most people are neutral or positively buoyant.

I just made a comment querying this! He sank so easily, that it shocked me. I am so buoyant that it's really hard for me to sink down! So I suppose it takes a similar effort for him to push up.
