What is Core Strength? Amazing Benefits & More


Whenever we talk about fitness, experts advise focussing on strengthening the core.

A core is an area around the abdomen, back, and pelvis. Strengthening the core means adding strength to abdominal muscles, back muscles, and the muscles around the pelvis.

Core strength is not only crucial for athletes and sportspersons. A strong core benefits everyone, including children, older adults, and people with sitting jobs. It makes our day-to-day tasks swift and improves overall well-being.

Core muscles are broadly categorized into deep core and shallow core muscles. They support spine stability and protect and reduce stress on the spine.

In this article, we’re going to talk about

  • Why is core strength important?
  • What are some major core muscles?
  • The benefits of strengthening your core

Eager to learn more? Let’s dive in.

Why is Core Strength Important?

When the deep and shallow core muscles are strong and function together normally, spinal stability is maintained, and the load on our intervertebral discs is reduced. Core muscles are used in almost every movement of our day-to-day life. 

Weak core muscles might cause dysfunction resulting in neuromusculoskeletal issues like muscle spasms, back pain, and neural compression. 

Strong core muscles can prevent injuries or falls during sports and other activities. But it does not mean you do not need a strong core if you are not physically active or a desk job person. Prolonged sitting, typing, or computer use can make our back muscles stiff and sore; therefore, it is advisable to keep your core muscles engaged, loosen up a bit, and breaks in between.

Major Core Muscles

The major muscles of the core are:

  1. Transverse abdominis: These muscles support skeletal alignment, withhold bowel movements, and facilitate contractions during childbirth.
  2. Multifidus: They are involved in all anti-gravity activity. The multifidus stabilizes the vertebrae as the spine moves.
  3. Internal and external obliques: Oblique muscles can work both unilaterally and bilaterally. Internal oblique muscles help maintain intra-abdominal pressure in micturition, defecation, and childbirth. While external obliques help rotate the trunk, assist in breathing, and help pull the whole chest downwards. 
  4. Erector spinae: This muscle is located on either side of the vertebral column and helps maintain a steady posture during walking, 
  5. Pelvic floor muscles: They help support the functions of the large intestine and reproductive organs. Pelvic muscles can become weak post-pregnancy, menopause, or due to chronic constipation. 
  6. Abdominal muscles: They protect the spine, help keep the body stable, and hold the organs in place by regulating internal abdominal pressure.
  7. Diaphragm: Diaphragm muscles are primarily used during breathing and are located below the lungs and heart. These muscles contract when we inhale and relax when we exhale. They also keep pressure on the oesophagus to prevent acid reflux.

11 Benefits of Core Strength

One can enjoy these benefits by practising core strength exercises in the daily workout routine. 

1. Lower back stabilization

Core exercises are perfect for stabilizing your back and improving balance and alignment. Studies support core strength training as an effective strategy to alleviate chronic low back pain 1.  

A study was conducted on 120 subjects aged between 20-60 years suffering from lower back pain. Participants were treated with routine core stabilization exercises for six weeks, and at the end of the study, the participants reported a remarkable reduction in pain 2

2. Increases adaptability and flexibility

Core exercises focus on strengthening and conditioning deep trunk muscles that work together to stabilize the spine. These exercises also positively affect muscles that improve balance and flexibility 3. It has been observed that young people have neck, back, and shoulder pain predominantly. Experts suggest that core training must be a part of rehabilitation and injury prevention programs to enhance dynamic and static balance. 

3. Assists with balance

Balancing is a key component even for performing simple day-to-day activities. Beginners, people on certain medications or with conditions like arthritis may have difficulty coordinating and balancing. It might also occur due to ageing. Core stability training targets the muscles within the abdomen, pelvis, and shoulders, providing the foundation for all arm and leg movements. Progress in balance performance is associated with improvements in leg strength. 

A study on older adults observed improved endurance and muscle strength after introducing a 6-week core strengthening home exercise program 4

4. Better posture

Weak and unbalanced core muscles might result in slouching. A good posture not only helps us breathe better but minimizes everyday wear and tear on the spine. A strong and upright posture always leaves a powerful and confident impression. 

5. Better exercise technique

Core exercises strengthen posture and coordination, helping us understand and perform exercises with a correct and better technique. The chances of injuries and muscle soreness are reduced, enabling the person to perform heavy thrust movements easily.

6. Improves stability

Balance exercises are essential as we age. Core training enables the body to move freely in any direction or stand at one point without losing balance, like climbing stairs or lifting heavy weights. All the muscles are engaged better; as a result, the strain on muscles and joints is also reduced.

7. Increases power

Core exercises are the best for boosting power. The core plays a significant role in generating power during sports like boxing, mixed martial arts, etc. A strong core is also needed to transfer power during activities like launching a kick or throw. Energy is transferred through the core into the upper body ending up at the shoulders, arms, and wrist. 

8. Supports strength training

Core stability is required to lift heavy weights. Strong core muscles are necessary to strength train effectively. A strong core means a better foundation to bear heavy weights during strength training.

9. Aids in healthy ageing

Ageing takes a toll on strength, coordination, and balance ability. A strong core eases back and joint pain, improves posture and balance and curtails injury risk and fall fractures. 

10. Increased core muscle power

Core exercises train the muscles of the lower back, abdomen, hips, and pelvis. They amplify core muscle health so one can train for a long duration with correct posture and breathing control. 

11. Make running more convenient

Core strength is necessary if you are a sprinter, marathon runner, or triathlete. It can aid your running form, speed, and respiration. Core muscle fatigue can impair high-intensity running performance. 

Core muscles allow multi-joint muscles to work more efficiently to control spine motion. The higher precision and steadiness of distal extremities may cause it. 

To determine the effect of core strength training on running ability, 28 runners practised core exercises for six weeks. A significant reduction in the completion time was observed in the 5000 m run at the end of the study 5. Therefore, it won’t be wrong to say that core workout benefits running.
