Symptoms of a Weak Core

In this section, we will examine typical indicators that many reveal insufficient core strength. These signs are frequently overlooked, but they can indicate a need to improve your core stability. Keep reading to learn more and keep your core strengthened today!

1. You Experience Pain in Your Lower Back

You Experience Pain in Your Lower Back

Are you tired of dealing with persistent lower back pain that just won't seem to go away? Did you know that weak core muscles could be the culprit?

It's true! Your core muscles play a critical role in supporting your spine and helping prevent injuries. Without a strong core, you may find yourself developing poor posture and experiencing discomfort or pain in your lower back.

2. You Lack Power & Stability in Your Upper Body

If you struggle with upper body exercises like pull-ups, weightlifting, or even swinging a bat, it could be a sign of weak core muscles. Your core muscles provide the foundation for power and stability in your upper body; without that support, your performance may suffer.

Not only does a weak core limit your ability to perform these exercises, but it also increases your risk of injury. As you compensate for the lack of core strength, you may overuse other muscles, leading to strains and sprains.

But it's not just athletes or weightlifters who need to be concerned. Lack of upper body strength and stability can also impact everyday activities like carrying groceries, lifting a child, or opening a heavy door.

Fortunately, there are ways to improve your core strength and enhance your upper body performance. By incorporating targeted exercises that engage your core muscles, such as planks, you can build a strong foundation for your upper body movements.

3. You Lie on the Floor & Feel Like Your Spine is Sagging

You Lie on the Floor & Feel Like Your Spine is Sagging

The third sign of weak core strength is a feeling of your spine sagging when you lie on the floor. This can be a telltale sign that your core muscles are not strong enough to keep your spine stable in a neutral position.

Picture this: you're lying on your back with your knees bent, hands resting by your sides, and your spine resting on an imaginary line. If your core muscles are weak, you'll find that your back is sagging towards the ground.

Like a clothesline that sags under the weight of wet and heavy clothes, a weak core can cause your spine to sag, leading to poor posture and back pain.

A strong core is crucial for maintaining good posture and preventing back pain. Your core muscles help to stabilize your spine and keep it in a neutral position. Without core strength, your spine can easily become misaligned, leading to discomfort and even injury. Fortunately, there are several exercises you can do to strengthen your core muscles and alleviate these symptoms.

Planks, crunches, and back extensions are great examples of exercises that can target your core muscles and improve your core strength. As you strengthen your core, you'll notice that your spine becomes more stable, and you'll feel less sagging when lying on the floor.

Don't ignore this sign of weak core strength - it's an opportunity to take action and improve your overall health and fitness.

4. When You Bend Over, Your Stomach is Sticking Out More Than Usual

If you find your stomach sticking out more than usual when you bend over, it could be a sign of weak core muscles. A strong core helps hold your midsection firm and stable, allowing you to maintain good posture and prevent excessive lower back arching.

However, if your core muscles are weak, you may find that your abdomen protrudes forward when you bend over, which can put unnecessary strain on your lower back and lead to discomfort or pain.

This can also be a sign of other factors, such as an increase in body fat around your core, but regardless, it's essential to pay attention to this sign and work on strengthening your core to prevent further issues.

5. You Feel Your Back & Shoulders Sagging and Tightening up During Weight Lifting

If you've ever experienced your back and shoulders sagging or tightening up during weight lifting, it could be a sign of weak core muscles. A strong core provides a stable foundation for your upper body, allowing you to lift weights with proper form and technique.

Without a strong core, your back and shoulders may compensate for the lack of stability, leading to discomfort or injury.

When lifting weights, pay attention to how your back and shoulders feel. If you notice them sagging or tightening up, take a break and focus on strengthening your core.

6. You Have Difficulty Standing Up From a Squatting Position Without Using Your Hands for Support

You Have Difficulty Standing Up From a Squatting Position Without Using Your Hands for Support

If you find it challenging to rise from a squatting position without using your hands to support yourself, it could be a sign of weak core muscles.

Your core muscles are essential in stabilizing your body during movements like squatting. Without adequate core strength, your body may be unable to maintain proper alignment, making it difficult to stand up without additional support.

Not being able to stand up from a squatting position without using your hands can indicate a weak core and can lead to further complications in your lower back, hips, and knees.

7. You Lack Balance and Stability in Your Lower Body

You Lack Balance and Stability in Your Lower Body

Have you ever felt unsafe or unstable standing on one leg or trying to balance on an unstable surface? This could indicate that your lower body strength and coordination are lacking due to a weak core.

Your core muscles stabilize your pelvis, hips, and lower back. You may struggle to maintain balance and coordination in your lower body movements if they are weak. This can make it difficult to perform exercises like lunges, squats, and deadlifts, which require a strong and stable base.

Additionally, a weak core can lead to compensations in other parts of your body, such as over-reliance on your arms or legs to maintain balance. This can increase your risk of injury and decrease your overall performance.

Strengthening your core muscles is essential to improve your lower body strength and coordination. Exercises like planks, bird dogs, and side planks are great for targeting your core muscles and improving your stability.

You can also incorporate balance training exercises like single-leg deadlifts and stability ball exercises into your workout routine to challenge your balance and coordination.

8. You Experience Pain in Your Lower Abdomen or Back

You Experience Pain in Your Lower Abdomen or Back

If you experience pain in your lower abdomen or back, it could be a sign of weak core strength. The core muscles are responsible for supporting the spine and maintaining good posture, and if they are weak, they can cause pain and discomfort in these areas.

Weak core muscles can also lead to an imbalance in the muscles of the lower back and abdomen, which can cause further strain and pain. This can lead to difficulty performing everyday tasks, such as lifting objects, bending over, or even sitting for extended periods.

To alleviate this pain and strengthen your core muscles, it's important to incorporate exercises that target the muscles in your abdomen, lower back, and hips.

9 .You Have Difficulty Walking Upright Without Swaying Towards One Side or the Other

Do you feel like you're leaning to one side when you walk? This might mean your core muscles are weak. Core muscles help you keep your body stable and balanced.

When these muscles are weak, you may struggle to walk upright without swaying. This lack of balance and stability can not only be frustrating, but it can also increase your risk of falls and injuries.

By strengthening your core muscles through exercises like planks, Russian twists, and bicycle crunches, you can improve your balance and reduce your risk of injury.

10. You Have Difficulty With Everyday Tasks That Require Core Strength

 You Have Difficulty With Everyday Tasks That Require Core Strength

A weak core will make it difficult to carry out core stability exercises such as lifting a child, carrying a bag of groceries, or holding a box in your arms. It can also make everyday core strength activities like paddling a kayak, playing with your kids, and walking up the stairs difficult.

Your core muscles help keep your spine stable and working well so you can do the activities of daily living without experiencing pain or discomfort.

Core stability exercises will strengthen core muscles making it possible to perform core strengthening tasks more easily and with less stress on your body.

Exercises to Strengthen Your Core Muscles

Looking to strengthen your core muscles and improve your overall fitness? Incorporating targeted exercises into your routine can help improve posture, reduce lower back pain, and enhance athletic performance. Here are five effective exercises to strengthen your core muscles.



A plank is one of the best core-strengthening exercises. It works on the entire core by challenging your abdominal, lower back, and shoulder muscles. Your core works to support your spine while holding a plank.

  • Rest your forearms on the floor with your elbows directly underneath your shoulders and hands facing forward to form a ninety-degree angle
  • This position requires you to keep your back straight and balanced on the balls of your feet and elbows
  • Ensure your head, shoulders, hips, knees, and ankles are aligned straight
  • Keep your lower back from arching and hold the position

Ab Wheel Rollout

Ab Wheel Rollout

Ab wheel rollouts are one of the best exercises for a strong core. The exercise strengthens your abs, shoulders, and arms while burning fat all over your body.

This exercise will work 20 different muscles simultaneously, including more than just your abs, because you will need to tense up other major muscle groups to succeed with this exercise.

  • Put both hands on the ab roller and kneel on the floor.
  • Place the ab roller in front of you. Slowly roll the ab roller out as you stretch your body straight.
  • After the pause, start to move back to the starting position.

Hanging Knee/Leg Raises

Hanging knee/Leg Raises

These core strengthening exercises are also one of the best core workouts because they strengthen your abs, lower back, and hip flexor muscles by working them all at once.

  • Hang from a pull-up bar or gymnastic rings with your body in a straight line and use an overhand grip.
  • Bend your knees and use your lower abs to raise your legs. Your thighs should be parallel to the ground at their highest point. Lower them under control back to the starting position.
  • The best way to strengthen your core is by performing high-rep sets that tire the muscle out. The slower you move each rep under complete control, the better results and speed of those results.
  • You can do different variations of this exercise, such as hanging oblique knee raises and hanging trunk rotations.

If you want to make this exercise more comfortable for you, you can use a pair of ab straps that you can use to support yourself. By using these hanging ab straps, your focus will entirely be on engaging your core and getting a core workout.

V Sit Ups

V Sit Ups

V-sit exercises are a great way to strengthen your core by working multiple areas of the core simultaneously. In this exercise, you form the letter V with your legs and torso. If you are a beginner, you can use your hands to help. You can also do this with bent legs. The exercise is also an excellent addition to intermediate-level abdominal and core workouts.

  • Begin by contracting your abdominal muscles and try to tense up the core. Slowly raise your legs to a 45-degree angle with your torso.
  • Reach your arms forward or toward your shins as you are able. Make it a point to keep good posture with your spine and avoid rounding the shoulders. Do not hold your breath throughout the motion-continue breathing deeply.
  • Hold this V-shape for a few seconds if you are a beginner. When you are stronger, hold it for a longer time.
  • Keep your abs engaged and return to your starting position slowly.

If you are a beginner, have low back problems, or simply want to do this exercise comfortably, try using an ab mat. This tool is a covered piece of foam made specifically to support your spine, providing the perfect angle to work out.

Slider Knee Tucks

Slider Knee Tucks

Core sliders are useful core strengthening tools that are simple, easy to use, and improve core strength. They also help core exercises become more challenging by moving the feet closer or further away from the core.

Multiple studies have shown that core sliders can be used for rehabilitating patients who suffered recent back injuries, as they can strengthen core muscles without putting a lot of force on the spine. Sliders can also be used for core exercises that strengthen core muscles while putting less stress and strain on joints like knees and hips.

  • From a high plank position with both feet on sliders, brace your core muscles and pull both feet in toward your chest.
  • Avoid allowing your shoulders to hunch and lean inward, as doing so will hinder the effectiveness of the core stability exercise.
  • Slowly push your feet back to go to the planned starting position.


Core exercises are essential to living a healthier, more active lifestyle. When core muscles become weak, it can result in lower back pain. Core exercises help strengthen core muscles and prevent injuries by strengthening core stability. If you want to build core strength and endurance, incorporate core strengthening exercises into your fitness routine.
