Most men dodge a haymaker. Few will protect their liver, the number one area of their body which, if struck, will knock them down. Hard.

Most MMA courses provide vague diagrams and text, leaving most fighters confused. Attacking the Liver is an instructional video course where you will follow John Hackleman and his students, making instruction easy (and fun) to understand and execute. Following along requires simple equipment and can be done from home.

Why attack the liver?

THE LIVER IS UNIQUE The blood supply of the liver is unique among all organs of the body due to the hepatic portal vein system. Blood traveling to the spleen, stomach, pancreas, gallbladder and intestines is collected in whats called the hepatic portal vein which then delivers this blood to tissues of the liver. contents of the blood are divided up into smaller vessels and processed before being passed on to the rest of the body.

With a composition similar to that of a sponge, any strike or blow to the liver is essentially similar to squeezing the water out of a sponge.

The sudden drop in blood pressure will cause victims of liver strikes "keel over." The body tries to instinctively control the blood pressure, and if it can’t raise the heart rate or restrict the blood vessels your body will essentially enter shut down mode until blood pressure can be stored to near normal levels.

THE LIVER IS EXPOSED Unlike other internal organs, the liver protrudes from under the right floating rib. It's exposition makes it a prime target for left hooks or roundhouse kicks.

But don't take my word for it. Let's take a look at some of the most famous fight-ending liver shots across combat sports.
