Carter Williams started CrossFit when he found out he had a chance to be a contestant on "Survivor" in the Phillipines. In order to prepare to be a "Tarzan athlete," he went to Solution 1 CrossFit. 

"I fell in love with it," Williams said. "I realized that being a full-body athlete was right up my alley."

Williams said "Survivor" challenges and CrossFit are similar in that you're going to "be the master at anything, but be ready for anything."
