Years ago someone tracked these numbers down for Columbu in a few European competitions-
Powerlifting:
Bench Press 520 lbs.
Squat 655 lbs.
Deadlift 750 lbs.
Weightlifting:
Olympic Press 325 lbs.
Snatch 270 lbs.
Clean and Jerk 400 lbs.
In the 70's, you have lots of competition-
Chuck Sipes was crazy strong. A fellow named Bill Seno was an absolute beast in Bodybuilding and Powerlifting, winning major contests in both. Also a very good OL'er. He was still around in the early 70's.
