Do you see these people walking around all day long, who appear not to be that fat, but whose bellies stick out like they are preggo? This happens because their internal abdominal muscles are weak and loose. Don’t let this happen to you.
The best way to flatten your belly is to work your invisible abdominal muscles. The transverse abdominis lies beneath your rectus abdominus; the rectus abdominus of course being the muscle that most people refer to as “the six-pack”.
When you suck in your stomach and your waist appears to be flatter, the muscle responsible for this is indeed the transverse abdominis. The good news is that the transverse abdominis can be trained with exercise.
The old time famous bodybuilder Frank Zane perfected a move called the Vacuum, and you should too. To do the Vacuum, suck your belly button in towards your spine. Hold that position for 20 seconds, but for crying out loud, please breathe normally. I don’t want anyone telling the paramedics that Project Swole made you pass out.
Repeat the Vacuum 5 times. Do this workout several times a day every day. In due time you will train your transverse abdominis to stay contracted, perpetually sucking in your stomach and making it appear as though you have a flat belly.
The Vacuum won’t do a whole heck of a lot to develop your 6 pack, but it really works for flattening your gut.
