Freediver from PA now training Navy SEALs and Olympic athletes
For Kirk Krack, his workplace is literally fluid as he travels around the world as a freediving instructor.
“On one breath of air from the surface, we descend under the water for varying depths and various amounts of time,” he said.
Krack's deepest self-propelled dive, which means he uses his own kicking power to get down, was 263 feet. That required him to hold his breath for about two-and-a-half minutes, although he can hold his breath for up to seven minutes.
Growing up on the prairies, Krack laughed when asked how he became involved in such a water-dependent sport.
