Without a doubt, nice abs are a hallmark of a great physique. What makes great abs? For most people it is looking good in their bathing suit. If you do not already have a six pack, the first thing you need is to flatten your abs. A tight flat mid-section goes a long way toward your beach physique.

But what are the best ab exercises for flattening your stomach? Read on you may be surprised.

Your abs- basic anatomy

You mid section is composed of two sets of muscles. The abdominal muscles  can be divided into your Inner Unit and your Outer Unit.

The Inner Unit you cannot see, but works to flatten your stomach and support your spine as you move. The Inner Unit is made up of the transverse abdomens (TVA), diaphragm, pelvic floor and multifidus. Here is a link to an in-depth explanation of inner unit musculature http://www.coachr.org/innerunit.htm

The Outer Unit which are the muscles you can view are your lower and upper abs or rectus abdominis, obliques and lower back (erector spine).

Surprisingly, very little attention is paid to Inner Unit conditioning in most abdominal training programs, which are generally made up of crunches and their variants. Strengthening your inner unit muscles is important for overall core performance as well as aesthetics- a flatter stomach.

Here’s Why- when your inner unit is contracted your belly button moves in and up which results in a slight abdominal hollowing or your waistline getting narrower. When you contract your outer unit – abdominal bracing (like when you are about to get punched) your abs push out.

Here are some Inner Unit Exercises. We have provided one exercise from each position: standing, prone and supine. It is important to train your core from the different positions as well as with a variety of exercises in each position.

*Please note our complete ab training program 360 Degree Abs has all of these exercises plus complete conditioning for the outer unit as well. Our program is balanced between the different positions that you can train your abs in, for a balanced program and greater training effect. I highly recommend following a balanced training program vs. just adding some of these exercises to your current (likely unbalanced) training program for limited effects.
