5 Signs That You Have A Weak Core And How To Strengthen It


The core muscles have to be some of the most underrated muscles in the body. You have your core muscles to thank for many basic activities that are usually taken for granted; things like walking, standing upright, bending down, and yoga all depend on your core strength.

What are the Core Muscles?

A lot of people think “core” and “abs” can be used interchangeably, but the two don’t necessarily mean the same thing. Some of the muscles that make up the core are not abdominal muscles.

The core is the group of muscles that make up the center of your body, including your abs, back, hips, and pelvis. This muscle group is vital to maintaining proper posture, balance, and stability.

Most of your body movements require core stability. With a weak core, it becomes harder to do everyday activities such as walking, sitting, and even breathing.

Signs of a Weak Core

Lower Back Pain

Do you experience lower back pain that seems to never go away? This is a common symptom of a weak core. When your core muscles are not strong enough to support your spine, it puts extra pressure on your lower back, leading to discomfort and pain.

Poor Posture

Slouching, rounded shoulders, and a protruding belly are all signs of poor posture, which is often caused by a weak core. A strong core helps you maintain proper alignment and prevents your body from collapsing forward.

Poor Balance and Coordination

Do you stumble or have trouble keeping your balance while walking or doing other physical activities? This could be due to a weak core, as it is responsible for maintaining stability and balance in your body. You may also lack upper body strength and coordination. This would make it hard to do upper body movements like throwing a ball or doing pull-ups.

Digestive Issues

Surprisingly, a weak core can also contribute to digestive problems. When your core muscles are weak, your digestive system can become sluggish and less efficient.

Breathing Difficulties

Your outer core muscles play a significant role in breathing by supporting the diaphragm. The diaphragm is an internal muscle that controls breathing. So, if the muscles that support it are weak, it can be harder to breathe deeply, leading to shallow breathing and decreased oxygen intake.

Causes of a Weak Core

Sedentary Lifestyle

A sedentary lifestyle, which includes prolonged sitting or lack of physical activity, can lead to a weak core. Your core muscles need to be engaged regularly to maintain their strength and endurance.

Poor Posture

Spending long periods of time sitting or standing in a slouched position can weaken your core muscles over time.

Pregnancy and Childbirth

Pregnancy and childbirth can weaken the core muscles, as they undergo significant changes during this time. It’s essential to focus on core strengthening exercises postpartum to regain strength and stability.


Unfortunately, as we age, our muscle mass and strength naturally decrease. This includes our core muscles, which can become weaker if not properly maintained through exercise and physical activity.

Ways to Strengthen Your Core

You can increase core stability and strength by having a consistent exercise routine and making a few lifestyle changes. Here, we’ll list a few core-strengthening exercises, but if you think those are too challenging, you can check out these simple beginner exercises to improve your core stability:
