Further thought. . .
Al Gerard would train throughout the year with his new Trap Bar. Because of some injuries he'd use the Trap Bar exclusively to build more strength. As his competition neared, he'd switch back to squats and deads for a short time to re-learn the lifts and be able to utilize his new strength built with the Trap Bar. He couldn't just show up at a competition and squat, he had to basically remember how to do them.
