Did a search this morning and found that the official one rep pullup record is a bit above 400lbs. Not to offend, but that is so bogus, when men, past & present, have exceeded that many times (the great Marvin Eder did 8 reps, wide grip at 202bwt totaling 402 lbs
Those were "historical performances" if we are talking official records they are going to be lower since witnesses and documentation is needed. 402 total and 206.2 added are current and obtainable to anyone who trains pullup seriously. My goal isn't to be the strongest at weighted pullups it's to encourage people to do them more often and get the very best to make their records official.
