cough cough bullshit...I guess its possible, but 100lbs????? come on. I found this. This is Bill Kazmaier's workout
Light Day: Regular bench presses, 225/10, 315/10, 410/3/15. Narrow and wide bench presses, 350/3/10. Dumbbell presses, 100/3/10. Front raises, 75/3/10. Lateral raises, 75/3/10 . Modified triceps presses, 300/4/15. Decline triceps presses, 335/3/15.
If the strongest man who ever lived, worked out with 75lbs, it's pretty crazy that you can do 100lbs for reps.
Just my thoughts..
