I think it's kinda like a poor man's rowing machine. At least that's how it feels the next day. What I'm doing is lying under my dining room table and grasping either the sides or the front edge and then pulling myself up until my nose comes close to touching the underside of the table. Sometimes I mix it up by placing my feet on a wooden bench as I do this.
On a side note, I love exercises like this that don't use weights and force you to get creative with what's on hand. Feel free to share more like it if you know some.
