I'm not sure what's up with the "sport, sporty route" thing or the "Aron ralston Ray Charles" Comparisons, maybe pigsteak and mike just hit their heads a few to many times. As for opinions about trad vs sport it's preference. Climbing is climbing, give it a rest no one is here to deflate your ego, or are you so insecure that it makes you feel better?
Obcessed is what lazy people call those of us who are dedicated!

Back to our regularly scheduled geek out.
Not to over emphasize the importance of one arm strength (as I said, I have limited one arm strength, but manage to climb a bit despite these short comings. Nonetheless, I would like to develop more static one-arm power)
With that full disclosure (and I will beat you, OB Juan, to it. I am pathetic), onward...
So. Check this out. I dreamed this little gem up several years ago. I think it could unlock the world of one arm power for even the most spindly armed of us. There is hope for you too, Horatio. No longer do you have to suffer the humiliation of having Ray kick sand in your face at the cliff as he makes off with your dog, laughing his high maniacal cackle.
You will be able to confront him and say, "Stand back dude. Or I will bust out a little one arm pull up on your ass." You can grab the start jug to Ale 8 One and knock out a one armer and Ray will melt into submission.
Okay, so enough of the Ronco commercial..
I call this the Archimedes Crank machine (that is proprietary).
What you do is take a 1 1/2 to 2" piece of wooden dowel about 16-18" long. From an over head weight bearing point (a rafter, your wall, a door jamb, etc.. something you would ordinarily do a pull up from), hang a single loop of cord/ rope/ webbing. The loop should be about 4-5" long. Load the dowel through it and rest the dowel on the loop at some variable mid point. Presto! You have a lever mechanism. You place a hand on either side of it and do a pull up. To keep the dowel level the forces have to equal out with the length of the lever arms. If you want to use equal force with each arm, the lever arms have to be equal (remember physics 211?). However, if you want to start placing incrementally more force on one arm, just slide the dowel over to one side in whatever increments you choose. You can make infinitesimally small changes in the length of the lever arms and make correspondingly infinitesimally small changes in the forces necessary to equal the two lever arms. With the principle of increasing resistance (increasing force), over the period of weeks to months, train each arm to become stronger (muscle hypertrophy) to adapt to the increasing loads. Pretty soon you have the dowel slid all the way over to one side and are doing a one arm pull up with a minimal assist from the other hand.
Archimedes said, "Give me a lever arm long enough and I can move the world."
Elegant, isn't it?

God, I am such a pathetic loser.
