Bill Pearl is one of my favorite old-school bodybuilders who doesn't get nearly enough praise for his accomplishment.
In 1971, he mopped up the floor with three-time Mr. Olympia, Sergio Oliva, along with Dave Draper, Frank Zane, and several other IFBB legends, to win the NABBA Universe.
I remember using his "20 Months to a Champion's Physique" articles in IronMan magazine. That was great stuff. "Train; don't strain", similar to Haney's "Stimulate; don't annihilate" mantra. That's when I stopped training to failure, which helped me recover from my workouts.
