I found this interesting! The whole article is here
...but this was a cool section here I think:
In 1993, Tom Platz, owner of perhaps the biggest wheels in bodybuilding history, entered into a squatting competition with Fred Hatfield (aka "Dr. Squat"), the first guy to squat 1,000 pounds.
Although Tom's legs were much bigger than Fred's, Fred kicked his butt in a one-rep max, hoisting 855 pounds to Tom's 765 pounds. But when they took some plates off the bar and decreased the weight to 525 pounds for a test of lower-body endurance, Tom dusted Fred, performing 23 reps compared to Fred's 11.
Fred Hatfield, and Tom Platz
Bottom line is, bodybuilders seem better at high reps with a smooth cadence, whereas powerlifters seem more adept at low reps performed explosively.
Mr. Olympia Jay Cutler wrote some very honest and forthright commentary on strength and muscular size in his Muscular Development
column in 2010. He listed his all-time best lifts along with his current strength. He used to train with much heavier weights several years back, but he's more muscular now than he was back when he was much stronger. While he still goes heavy, these days he focuses more on quality than quantity.
