Chaps,
It is very interesting that you are using this lift in the USA.
As for origins (of the Name anyway) , it was a lift created by Tony Cook around 1999 in honour of his gym member Paul James, who used to show off his shoulder flexibility after making a cclean by pressing the bar overhead and maintaining the full squat, all the others who tried it fell flat on their arses much to the mirth of Paul.
I think Paul was good for about 70kg on this, his press being the limiting factor not his flexibility.
The complete lift got a bit complicated, you had to clean the bar, front squat, hold the full squat position, press, complete the squat and then return the bar to the floor, thinking about the order was harder than teh actual lift !!!
This was competed in a BSAG comp, where I managed about 60kg.
As for a 150kg press, I would love to see that in PRINT.
regards, just thought you would like to know the origin of the name.
