Performing the Exercise

  1. You can position yourself for this exercise in several ways, but standing up straight is the simplest way to begin. Stand straight and keep your shoulders back so that you're not slouching. [1]
    • While standing straight with good posture is best, comfort is more important, so don’t strain yourself by standing too erect.
    • You can also do this exercise on your back, on your stomach, sitting down, or kneeling. [2]
  2. Take a deep breath in, filling your lungs up with air. Take your time and continue inhaling for roughly 3-5 seconds. [3]
    • If your nose is congested, breathe in slowly through your mouth instead.

  3. Let out the air through your mouth instead of your nose for more control over your breathing. As you exhale for around 5 seconds, pull your stomach muscles inward and hold. [4]
    • Try to exhale all the air through your mouth in roughly 3-5 seconds.
    • You may also want to add a pelvic tilt as you contract your abdominal muscles to work your lower back.
  4. While you exhale, suck in your stomach as far as it will go. To get the best muscle workout possible, picture flattening your belly button against your backbone. [5]
    • The stomach vacuum is an isometric contraction (tensing the muscle without moving it) and can seriously strengthen your abs and back by exercising the transversus abdominis (TVA), which is your deepest abdominal muscle.
    • If you can’t suck your stomach in very far, that’s okay! This step takes practice, and your ability to execute it properly will improve over time.
  5. If you’re just learning this exercise, you may only be able to hold it for 5-10 seconds, but as you improve, holding this position for 20 seconds is ideal. It’s okay if your stomach protrudes again as you fill your lungs with air, just keep holding your muscles tight. [6]
    • Don’t feel the need to hold your breath while you perform this exercise, as continued inhales and exhales are expected.
    • Regularly practicing this exercise will help you increase the time you can hold your breath and contract your stomach muscles, eventually reaching as long as 60 seconds.
  6. Allow your muscles to relax and let your stomach fall into its original position. Then, take a nice, deep breath in. [7]
    • Remember to do this exercise slowly and carefully, monitoring your breathing.
  7. People with more experience doing this exercise can go up to 10 times before stopping, but starting with 5 reps is best. Breathe in and out deeply each time, counting the seconds of how long you’re able to hold in your stomach. [8]
    • You may need to break up the stomach vacuums. For example, you could do 2, then take a 1- or 2-minute break before doing another 3.
    • Stomach vacuum 3-4 times a week. You should notice your core getting stronger around 3 weeks after starting!

Choosing a Position

  1. Stand with your feet shoulder-width apart, making sure they’re both flat on the ground. Keep your back straight as you breathe in and out, repeating the same sucking-in technique for around 20 seconds. [9]
    • You can do this while standing in line at the store or even when you're cooking in the kitchen.
  2. If you’re in the car or sitting at work, you can still do these exercises to strengthen your body . Sit up straight in your chair and place your hands beside your thighs (if possible). Relax your shoulders by keeping them down and slightly pulled back. Begin breathing in slowly and exhaling all the air in your lungs before sucking in your stomach and holding the position for around 20 seconds. [10]
    • It’s especially important that you have great posture while doing this exercise if you’ve chosen to do it sitting down, as slouching may cause muscle strain.
  3. As you lie on your back, bend your knees, so your feet are flat on the ground. Place your hands on the ground next to you, and begin breathing in slowly before exhaling all of the air in your lungs. Then, suck in your stomach and hold the position for around 20 seconds in reps of 3. [11]
    • You may opt to round your body by lifting your head and shoulders slightly forward off the ground to make this exercise more effective.
  4. Place your hands with your palms flat on the ground right below your shoulders. Then, place your knees on the ground so that your legs make a 90-degree angle with the floor. The tops of your feet should be resting on the floor so your heels are off the ground. Breathe in deeply and suck in your stomach for 20 seconds while holding this position. [12]
    • Look down towards your hands as you hold this position.
    • Keep your back straight and avoid arching it.

    Yes, although you need to make sure that you're breathing from your diaphragm. It's really essential. If you don't, you're really not going to see a ton of benefits.

    Expert Answer
    Yes! It can definitely be a little tricky. I think it often helps to picture it as a kind of single motion. Imagine yourself drawing in the skin just above your pubic bone. Then, pull your stomach in at an upward angle towards your spine. Once you feel the deepest part of your core engaged, you've got it!

    The transversus abdominus, which is the deepest muscle in your core. This exercise is popular because it's usually really hard to exercise that part of your body.

      About This Article

      Article Summary X

      The stomach vacuum exercise is a great way to strengthen your abs and help improve your posture To do the stomach vacuum exercise, first stand up straight and breathe in through your nose for 5 seconds. Then, slowly exhale through your mouth for 5 seconds while sucking your belly button in as far as it will go. Hold your stomach in for at least 20 seconds. While you contract and suck your stomach in, continue breathing. After 20 seconds, release your stomach muscles and allow your belly to expand. That counts as 1 rep. Do 5 reps per workout. Over time, work your way up to holding your stomach in for 60 seconds per rep. You can do the stomach vacuum exercise in a variety of other positions too, like sitting in a chair, lying down, or while doing a plank. For more tips from our Personal Training co-author, including how to do the stomach vacuum exercise sitting or lying down, read on!
