True, Carl may not have had a big squat which is a indicator of absolute strength, but it was pretty obvious that his elastic strength was outstanding, and that is one of the things that allowed him to attain such great hip height. You can actually see the change in his sprinting technique if you look at very old videos of him, i.e. circa 1981-1982 and compare them with 83->92…96. I would venture a guess that the specialized jump training combined with the technical changes he learned from Coach Tellez were contributing factors.
