5 Signs Your Core is Weak – And What You Should Do About it!

Core Strength

A strong, healthy core is important for our health and posture. When your core is strong and working properly, you will have less back pain, better posture, and will move with more ease and endurance.  But how do you know if your core strength is where it needs to be? I can tell you that chiseled abs, a thin waist, or the ability to do a hundred sit-ups are NOT reliable signs of a strong core. Instead, here are five signs to know if your core is weak and what you can do about it:

1. Your Back Hurts

The most common side effect of a weak core is back pain, and yet most people still don’t consider core strengthening as a way to address those problems. Your core’s job is to support your spine and act as the center from which all movement stems. If those muscles are not properly conditioned – meaning, if they aren’t conditioned to engage when they are supposed to – your spine is at risk for being overworked, and muscular strain and tension are inevitable. The pain will most likely occur in your lower back, but can even occur in your neck, making simple tasks like bending, lifting, and walking totally miserable for you.

2. You Have Poor Balance

This may not be an obvious one – but one of the main culprits of poor balance is a weak core!  Your core muscles help to stabilize your pelvis, and a stable pelvis allows you to have better balance.  If the muscles around your pelvis (particularly your hips and glutes) are weak, then your balance will undoubtedly be affected. This may not be an issue that you notice right away.  But next time you’re walking across an icy driveway, you’re going to wish that your balance was at 100%. We incorporate an Australian based Maitland core strengthening program ( which includes some Pilates and also functional day to day movements) into our physical therapy practice because it is such an effective whole-body strengthening system that can really make a huge difference in core strength and balance. A strong, coordinated, and engaged core helps you to react to balance challenges more efficiently, and may prevent that next fall!

3. You slouch all the time

Most people struggle to maintain good posture when they have a weak core. It becomes so easy to slouch, and you may not even realize you’re doing it.  Observe your posture right now… Are your shoulders rolled forward? Is your low back missing its natural curve? Is your head poked forward? When you go to correct your posture, does it feel difficult or tiresome to maintain? If so, your core might need some endurance-training!  A lot of people will argue that core strength has nothing to do with your posture. But here’s the thing, a strong core makes it easier and more natural to have good posture, and when better posture becomes effortless, it starts to become your norm. Your whole body – especially your spine – will thank you.

4. Your feet and wrists hurt

Many of our clients come to see us with an initial complaint of foot pain (also known as plantar fasciitis) or wrist pain. It keeps coming back no matter how many times they get rid of it or go to physical therapy. Sound familiar? When you have a weak core, and lack the proper central support and stability you need, your outer muscles and joints will eventually suffer. We already talked about balance. If your core isn’t working to help you stay more stable, your feet will have to work harder, resulting in overtaxing of the tissue on the bottom of your foot. If your middle back can’t support you when you’re pushing or pulling, your wrists will take the brunt and this can result in stiffness or pain over time. If you’ve got any chronic problem that isn’t getting resolved over time, something is missing. In the case of your wrists and feet – it may be a sign of a weak core!

5. You’re always holding your breath

If you’re always being reminded to breathe when you move or exercise, this is another sign that your core is weak and not working properly. You’ve heard me talk about this before, but your deep core is made up, in part, of your diaphragm, which is your main breathing muscle.  When your core lacks stability, or in most cases, doesn’t know how to engage in the right way to give you the stability it needs, your diaphragm will contract to compensate. One of the most tell-tale signs that this is happening is that you always hold your breath during exercise. This is probably one of the most overlooked signs of a weak core, and one of the most difficult to correct! It’s why we dedicate a great deal of time reviewing this with our clients during their core strengthening programs that we teach them and it’s one of the most important things we work on with every single client as we prepare them to confidently return to exercise.

If any of these signs seem familiar to you, then you might want to start paying more attention to strengthening your core! But don’t just start doing sit-ups or planks haphazardly and expect good core strength to follow. Being able to do sit-ups and planks are the RESULT of good core strength. You must first learn how to strengthen your core properly. We’ve got an entire 8 week program that is custom designed to help people do exactly this. We can offer you a free 30 minute in-person assessment to see if your core qualifies for this type of strengthening.
