Freediver Guillaume Néry calmly descends to the bottom of the Y-40 Pool — the world's deepest pool at 131 feet — in Italy as his wife films the action.

Freedivers are able to train their bodies to do amazing things, and this video of Guillaume Néry descending to the bottom of the world’s deepest pool is proof.

Néry, a champion freediver from France, can be seen casually making his way to the depths of the Y-40 Pool, considered the world’s deepest pool by the Guinness World Records at 131 feet (40 meters). The pool, located at Hotel Terme Millepini in Padua, Italy, has an underwater tunnel for land-bound guests to visit, platforms and caves for divers to explore, and a tube descending all the way to the bottom. Y-40 holds more than 1.1 million gallons of water — kept at a toasty 91 degrees F.

Néry displays his grace and calm demeanor in the water — an impressive feat as I was left gasping for air at my computer — while his wife, Julie Gautier, films the action. Néry, 35, freedived past 380 feet at the 2011 world championship, so this feat does not rank among his most impressive dives, but it is a wonderful example of just how calm competitive freedivers must stay to hone their craft.
