You ever notice how old school bodybuilders like Arnold had insanely flat, almost concave stomachs?

Having massive, blocky ab muscles was important, but having a striking torso to waist ratio was a major point of emphasis.

Legend has it a lot of them used a special, and kind of odd, exercise to get their stomachs so lean.

It's called the stomach vacuum (fitness infographic below). Benefits include, not only tightening up the ol' belly, but also strengthening the support system around the spine, which carries over into a variety of big lifts.

(Arnold has even openly discussed the vacuum, both as a bodybuilding pose and as a technique for keeping a slim stomach)

If you want to learn how to take this "secret weapon" of legendary bodybuilders and use it to get a tighter midsection, you've come to the right place.

Stomach vacuum benefits and how to do stomach vacuums

Stomach vacuums are an isometric exercise that work the transverse abdominis (TVA) through static contraction.


 

What the heck is the transverse abdominis?

  • These are the ab muscles behind the ol' six pack

  • They're also sometimes called the “corset muscle” because they protect the spine and quite literally hold your gut in

 

What do stomach vacuums do?

  • Build rock solid posture and stability

  • Protect against injury during heavy lifts

  • Improve core engagement during other ab exercises

  • Fight protrusion of the stomach for a flatter tummy!

 

Alright, how do I do stomach vacuums?

You can do stomach vacuums pretty much any time, anywhere, and every single day if you want. Here are the basic steps:

  • Exhale completely while standing

  • Pull in your stomach as hard as you can from the belly button

  • Hold as long as you can go without a breath

  • Take a few breaths and repeat

  • Start small and work your way up to longer holds and more reps

A good structure of stomach vacuum sets and reps to follow: Try 3 sets of 10-20 second holds at first. It will be hard, but as it gets easier, bump up the time of the holds to 30 seconds or more. Eventually you may be able to do multiple sets of minute-long holds, or even more.

 

A little real talk about stomach vacuums:

  • Stomach vacuums won't burn fat without regular exercise and a solid diet

  • Their slimming effects will be strongest on people who are already somewhat lean

  • The good news? Their posture, stability, and strength benefits will work for everyone!

 

Quick tips for stomach vacuums:

  • Always do stomach vacuums on an empty tummy (food will make it hard to fully contract the muscles)

  • Pump your stomach in and out during holds without taking a breath for extra work

  • Try them lying flat on the ground, on all fours, or sitting to ramp up the difficulty

 

How long to see results with the stomach vacuum?

Most experts say you can expect to see some noticeable differences in your midsection within just two to three weeks of doing the stomach vacuum exercise, even claiming you'll knock off as many as three inches off your waistline.

I think that's a wee bit ambitious, and I'd temper expectations just a little bit. Results with the stomach vacuum will vary for everyone, but the key will be consistency in your training. I think it's far more likely that the results will be more visual and aesthetic then measurable, especially that early, but over time you may see a significant difference in the flatness of your stomach.

Again, though, one of the keys is going to be staying lean and maintaining a low body fat percentage to get the full benefits of the stomach vacuum. However, many of the benefits of the exercise will be unseen, like better support for your spine and improved posture.

 

My experience & before and after with stomach vacuums:

I've been doing stomach vacuums casually for a few weeks now and have noticed a few things:

Greater control over the movement. I'm starting to really be able to get my stomach to curve in under my ribcage more and more, as a result of those TVA muscles getting stronger. Some people get so good at this movement that they can control expand and contract individual ab muscles, which looks super freaky but is way impressive!

Extra tightness. Like I said, the vacuum won't burn fat, so a lot of the visual difference in my stomach is due to leaning down (I've lost about 7 pounds over the past two months). But there is a certain tightness and... elevation? for lack of a better word there that wasn't there before. I see what people mean about the TVA acting as a bit of a corset and holding your stomach in tighter to your body.

Hope this guide helps!

And remember, stomach vacuums aren't the end all be all to getting the six pack you've been dreaming of. Your best bets are still regular diet and exercise, along with traditional strength training and ab work. But stomach vacuums are an excellent and WAY underutilized method of getting that extra 10% of definition and slimness that can make a big difference.
