Yes, lets all try landing with a loaded bar on our upper back. The force becomes impactual to the entire spine, the discs in your thoracic and lumbar spine, and the cartilage in your hips, knees, and ankles. Once any of these are displaced or crushed, or injured...you are done. What could possibly convince people to try movements like this? I am a chiropractor and I can tell you, I have seen the MRI's and CT scans from stunts like this..not pretty and completely non-necessary. There is zero need for impactual forces when loaded with a weight. I couldn't hardly create a more dangerous setup. First, do no harm people.
