I saw this movie a few years back. Where this guy goes to the marines, or bootcamp, something like that, and trains better than anyone else their, beats everyone's record, at the end of the movie, the guy was in a helicopter rescuing men from the ocean in a hurricane and he held on to this one guys fingertips for like 8 seconds or something, and he beats this guys record. ii wish I knew more about the movie but that's all I can recall.

Sounds like The Guardian (http://en.wikipedia.org/wiki/The_Guardian_%282006_film%29)
