The sjoutrunz is a bodybuilding technique involving lifting leather briefcases filled with lead or other heavy material.

The inverted sjoutrunz is a nasty variation of above. It was invented by Marco Venturini-Autieri while training with his sparring partner Seán. It consists of executing the sjoutrunz while hanging, upside-down, from an elevated bar, with the ankles tightly tied. Enough breath must be spared because, during the reps, a few chapter s of Arnold Schwarzenegger’s bodybuilding bible must be read aloud.

It is recommended to execute the inverted sjoutrunz with empty stomach.
