Wouldn't it be cool to be able perform just one of these exercises?

I'm getting more and more interested in bodyweight exercises and calisthenics after seeing videos like these. Wouldn't it be cool to be able to perform just one of these exercises? The guys in these videos look more fit than any other athletes I've seen. The pull-up bar rules!

My goal in 2014: Be able to perform one hand pull-up by end of year.
