How to tighten your core, abs during exercise (and why it’s so important)

by | Aug 12, 2015 | 19 comments

In this week’s #QandAWed video we tackle a really valuable question, “how do I tighten my core, abs?” Since this is such an important topic, I wanted to go into more detail than we did in the video here with this post to explain a few key points further and to offer some specific workouts to try to further develop core strength.


What exactly is your “core?”

Your “core” muscles involve much more than just your abs – in fact, these spinal stabilizing muscles run from your shoulder blades, along your spine and back and include the four muscles of the abs (transverse abdominis, internal and external obliques, rectus abdominius) as well as the major muscles in the hip.


How do I engage it?

The various cues for core engagement may vary depending on the specific movement you are doing, but in general, here are a few ways to turn on the core muscles while standing:

1) Engage your abs from the inside out by drawing your belly button into your spine (without holding your breath or ‘sucking in’ your stomach) and focus on holding the contraction of the abdominal muscles.

2) Press your shoulder blades down and away from your ears (this helps to ‘cap’ the contraction of the abs and engages the core muscles in your back).

3) Think of ‘lifting up’ through the pelvic floor to engage the muscles in the pelvic floor and deepen the contraction of your abdominal muscles. While not necessarily a defined part of your ‘core,’ contracting the pelvic floor muscles can help you maximize your abdominal contraction, and may additionally build strength in the pelvic floor at the same time.

Try it out — with feet hip-width and knees slightly bent, imagine standing on a unstable surface (like a rocky ship or subway train) and shift your weight quickly from one foot to the other, maintaining all of the contractions listed above (you can even place your hands on the sides of your waist to feel these muscles contracting).


Why is a strong core important?

Think of a strong core as your body’s support system – these muscles help you stand taller, move more smoothly, and potentially even lift more weight safely. By stabilizing your spine, your core muscles provide you with a strong, stable foundation for everyday activities like lifting heavy objects (like your toddler) and assist with movements that require balance and coordination (like jumping over that puddle at the last minute).

A strong core may also help boost your workout performance too, which could translate into both a better fitness level and faster results. One 2009 study done by researchers at Barry University found that 6 weeks of core training drills helped improve the performance of recreational and competitive runners.


What are some of the best ways to strengthen your core?

Targeted abs workouts can be great for engaging and strengthening the core, but don’t forget that you can also get build core strength from focusing on it during your total body workouts as well.

Aim for a mix of training that works your core in a multitude of ways, including exercises that involve challenging the core muscles to do what they are designed for — stabilize your spine. While most of our workouts involve engaging the core in some way, here are a few routines to try that really zero in on core strength.

These 3 abs-centric YouTube videos are specifically designed to help you practice deep core engagement:

#1: 15 Minute Core Concentration

#2: 12 Minute Standing Pilates for Flat Abs

#3: 15 Minute Crunchless Abs

And these 3 total body workouts that also challenge the core muscles while working the entire body:

#2: 35-Minute Straight Up Strength

#3: 30 Minute Kickboxing Ballet Body Sculpt

  3. Lauren

    I have had 2 previous C-Sections. I don’t have any feeling in my stomach so I cant feel when my abs are engaged and I noticed a firmness when I “clinch” and hold my breath. I don’t know if that is engaging them but I feel like I’m going to pass out when I do that…
    HELP 🙂

  4. Tina

    I can’t tighten my core and ab muscles without holding my breath, everytime I try to breath while having my muscles tightened it gets loose and just can’t keep it up. please help, I really don’t know how to dot this.

  5. Dawen

    Okay, so you say to “draw the belly button towards the spine without holding your breath or sucking in your stomach,” which is what my aerobics teacher also says and this doesn’t make sense. How do you do that? How /can/ you do that without sucking in or holding your breath? That’s the only way I know how to do that!

    Hi Jessica,

    Super amazing post!
    This is really helpful and so perfect! Just the exercise I was looking for.
    Cheers to you! and keep up the great work!

    One thing I have heard some pros say is to brace your core muscles like you’re preparing to get punched in the gut. That’s the only thing that has helped me understanding how to engage your core more than anything else. Hope that helps you too. 🙂

  8. Joy

    I have a lot of weight on my tummy and all the exercising does not seem to help. i have been exercising consistently over 3 months now – first with yoga and then I found your website. I started with the fit-in-15 which was completed 2 weeks ago and now I do other exercises from your channell – core, cardio. But my belly is still there. Help!

  15. Amy

    I have Degenerative Joint Disease in my spine and my doctor’s (and physical therapist) have determined and shown me how I have been using my core muscles incorrectly while exercising for the past 15+ years! Your tips above are crucial for everyone engaging in physical activity. Just because I have a relatively small waist, I thought my core was strong. WRONG!
    Thank you Jessica for such important information!

    • Jessica Smith

      Thanks for sharing that Amy! So glad you found this helpful. Thanks for reading and keep up the great work you are doing taking care of your body and your health 🙂

    One thing I try to always keep in mind is a tip of a friend (worth it ?) = we mustn’t have a blocked diaphragm to allow muscles of abs working well. In fact we must be rather relax and just think to breath !
