In all seriousness, you should try using "bone support" instead of muscle to hold and stabilize the camera. In NRA/CMP High Power Rifle competition, we teach the concept of "bone support". Use your skeletal structure to gain support and don't muscle the gun onto the target. The same concept is applicable for large lenses.IMAGE LINK: http://www.flickr.com/photos/ocabj/4847420206/
Note the back/flat of the arm upper arm is supported against the lower leg just below the knee.
I don't have a photo of me with a 70-200 in the standing position, but keep my support arm (left) close to my torso, just like when I shoot the unsupported standing stage of fire in a High Power Rifle match. Although, the main difference is that with a camera, my body is squared off more to the subject. Video of *rifle* standing practice session: http://youtu.be/_dgrU5ydWyY?hd=1
