Please Help

Hello,Blender community.I’am looking for help to model something like this:

No,its not what you may think it is.I have been trying to model this several times and couldn’t succeed.I need this so i can use it as the main body of a character from my game that is currently being developed

Can anyone teach me how i make this shape?

Something like this?
Create a cube, extrude in two directions, subdiv modifier, tweak to your liking…
