we all know Arnold was told by Reg Park to do sets of 10 with 1000lbs to make his calves grow, and alot of people have questioned the validity of the claim.
I remember reading in an edition of Muscle Mag International an interview with Mike Morris (remember him). He said that he once rigged up a machine with 1000lbs and got a few reps out of it, but calves dont respond to low reps so he never did it again.
Now if Mike Morris could rep with it, then why not Arnold? I know Mike had massive, powerful legs but then Arnolds werent too bad themselves
