A coach just saved a swimmer's life after she fainted in the water during a competition.

Anita Alvarez, 25, an Olympic artistic swimmer, was in the middle of her routine at the FINA World Aquatic Championships in Budapest, Hungary, when she lost consciousness and began sinking to the bottom of the pool.

Her Team USA swimming coach, Andrea Fuentes, realized something was wrong, and she dove into the pool fully clothed to rescue Alvarez.
