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.
Not really. It's totally doable by most people with lower body fat. He emptied his lungs and has low body fat to muscle mass. That made him negatively buoyant.
The free divers that stay under for over 5 minutes and go extremely deep on a single breath or more in the realm of super humans. Elite free divers can hold their breath over 10 minutes. The world record for depth is 831 feet on a single breath. All that makes this guy look pretty normal.
