I heard a rumour that Jon Pall used to read in his earlier training years George F. Jowett Training Course. It's a very old course about working out without weights. Just click on the link or use the tag system and click 'George Jowett' .
Furthermore the magazine "Powerlifting USA 1988 (mar)" cited that Jon Pall Sigmarsson followed the "Hatfield Training System".
There was no training routine included in this powerlifting magazine. Thus the following routine is just a example how Jon Pall may trained.

Jon Pall used the Hatfield Training Method. He trained every fourth day the back, every third day arms, every two days calves, every sixth day he trained the lower back and every fifth day to sixth day he trained legs.
All is done with proper technique.

770lb for six reps after only a six week training cycle. His best bench in training 551lb and 485lb for 6 reps.

His best squat in training 770lb for 3 reps

Best barbell curl: 220lb for strict 10 reps
Forarm curl: 310lb for 10 - 20 reps
He used to train his abs with 200 reps reach training session.
Jon liked to stretch and after training he used to run several sprints..
"I eat any kind of fish, most days of the week, throwing in a chicken or two and a beef steack."
His diet is similiar to the vikings: a lot of fish and milk products, shark meat, whale meat. But of course even Jon Pall cheated and ate sometimes fast food.
