To complete this goal: Take an aerial class- could be silks, corde lisse, trapeze, hammock, or lyra (though lyra might be a cop out, as I've already done that).
Why? I bought a groupon for 5 classes at a pole fitness place in my area last year. When I finally used it this summer, I ended up doing almost all lyra (aerial hoop) classes, and bought another groupon to take more. It is crazy, crazy fun! There's just something very empowering about pulling up your own body weight and dangling from the ceiling. . . I would really like to try some of the other aerial apparatus, especially silks (a blogger I follow is an awesome silk aerialist, very inspiring).
