Eder could bench 500, overhead press 350 and dip with 400+ lbs. i would like to see ANY bodybuilder now match all 3.
Park was the first BB'r to bench 500 and Pearl squatted 600 for reps.
Sipes was a very strong bencher, but don't know about his other lifts.
Columbu was a freak and his short size helped a lot.
Platz was a monster squatter and hack squatter.
Casey Viator should get a mention. 600 lb squats for reps, 225 lb curls, etc.
Just a few from the the pre 90 era.
