Isaac Caldiero (born March 2, 1982) is an American athlete, rock climber and carpenter, who competed on American Ninja Warrior in seasons five, six, seven, and ten. He is best known for finishing all four stages of the National Finals course in season seven and becoming one of the first three Americans (along with Geoff Britten, David Campbell in SASUKE Vietnam 2, and later Drew Drechsel in season 11) to achieve what is known as "Total Victory". Caldiero was awarded a $1,000,000 cash prize after completing Stage 4 in a faster time than Geoff Britten. Career Carpentry Caldiero is a carpenter by trade. Rock climbing Caldiero, a rock climber, has made first ascents and free-solos. He started climbing at the age of 15, and bouldering at 17, and specializes in highball bouldering.

Because Caldiero's climb was faster, he was declared the season's official winner, and he received the title of the first "American Ninja Warrior." Because Britten ran first, however, some fans and competitors considered him to be the "first American Ninja Warrior"; Joe Moravsky stated: "In my opinion, Geoff is technically the first American Ninja Warrior and Isaac is the second.
