What is a six pack??

A six pack is the perfect formation of stomach muscles on a guy, just like the pic above!

The 6-pack refers to the rectus abdominus muscle in the center of the human torso. While it looks like 6 different muscles, it's actually only 1 large muscle.

Then there is the transverse abdominals, which are more horizontal than the 6-pack muscles, and are also deeper in the abdomen itself.

Then on each side of your body are the internal and external obliques.

If you want strong and good-looking abs, work all of them and not just the 6-pack :)

A six pack is this before it goes to that
