Caine Eckstein is an Australian Ironman champion and a Guinness World Record holder. Recently, on the set of the Today show, he completed 4,210 pull-ups in 12 hours. This secured for him the record for the greatest number of pull-ups in both 12 and 24 hours.
To perform this incredible feat, Eckstein did 6 pull-ups every minute for the first 10 hours of his attempt, then 5 pull-ups every minute for the last 2 hours.
It really tore up his hands!
Maybe Eckstein will try it again sometimes with his pinkie fingers, as this man did.
