Is There a Record for Curls One Hour?

He'd trained for this for three months. So he found out that there was a world record for 550 curls one hour with a 50 pound weight. He did 600, but he still had 30 minutes to go in his hour so he ended up with one thousand 32 curls in one hourw pound. But also, he mentioned later that he hurt his back in the proer of doing that and sharing for that - so he never went back try to reclaim his records.
