Core Stability

What is core stability and how to reduce the risk of injury resulting from bad posture by improving it.

Core Stability can be described as ‘The ability to control the position and movement of the central portion of the body’.

Body Strength and Power is derived from the trunk region of the body and a properly conditioned core helps to control and utilise that power, allowing for smoother, more efficient and better co-ordinated movement in the limbs. Good postural strength will provide the foundation for ALL arm and leg movements.

The ability to maintain good posture helps to protect the spine and skeletal structure from extreme ranges of movement and from the excessive or abnormal forces acting on the body.

Ok, now for the technical bit…

Core Stability

Core Stability

Core Stability relates to the bodily region bounded by the abdominal wall, the pelvis, the lower back and the diaphragm and its ability to stabilise the body during movement. The main muscles involved include the transversus abdominus, the internal and external obliques, the quadratus lumborum and the diaphragm.

In addition, it is the lumbar spine that is primarily responsible for posture and stability, providing the strength needed for stability and support. Without core stability the lower back is not supported from inside and can be injured by strains and overloading of the area.

  • We want these stabiliser muscles to act by holding the lumbar spine in the neutral position, which is the correct alignment of the pelvis that allows for the natural ‘S’ curve of the spine, also known as Neutral Spine.

It is also believed that insufficient core stability and tight inflexible muscles can result in continual lower back pain and poor posture.

  • A well-conditioned and flexible core will help to reduce the risk of injury resulting from bad posture, overloading of a weak area or the sudden jarring resulting from slips, trips or falls.

It is not just the recruitment of these deep-trunk muscles that we are going to strengthen, but how they are recruited and looking at the timing and co-ordination of these muscles

Whenever a person moves to lift something or simply to move from one position to another, the core region is engaged first. This engagement of muscles / tension is usually made unconsciously.

Feeling a muscle work or beginning to notice it work, is not only a very useful tool as a training aid, but also proves you do have them!

Before undergoing any form of exercise regime; If you have any previous medical conditions, are pre or post any operations, have an on-going injury, feel dizzy or faint through exercise, suffer from heart pain or are unsure of any other condition / problem at any time please stop and seek GP / medical advice.

An example to try;

Sit in a chair and apply light pressure with your fingers into the side of your abdominal wall. From here simply lift one leg. You will feel a sudden engagement of the muscles.

Woohoo! Found them! Now to strengthen them!

Over the next series of Blogs I will show you easy to follow steps, not only on how to activate and work you’re core, but also on how to progress and feel the real benefit of having a strong, functional, flexible and powerful ‘Core’.


For next session you will need please;

  • Time, give yourself time to train. Timetable into your life a structured slot when you can have some ‘You Time’ to train.    ****Very Important****
  • An available space; to train, to sweat, to balance and to fall off your ball …….
  • A mat, thick / thin – for your comfort. Please note some people find it more comfortable having some sort of support underneath the neck. E.g. A rolled towel
  • A stability ball – N.B. Some of our workouts will be mat based although a majority of our workouts will be on a stability ball.
  • A sizeable mirror – If possible

Which size ball, after all size is important…

Ideally, while sitting on the ball, your hips and knees should be close to parallel with the floor (at a 90 degree angle). (If unsure ask someone to help).

Stability Ball Size Chart:

User’s Height Ball Diameter
under 4’10″ 16″ or 42cm
4’11″ – 5’4″ 21″ or 55cm
5’5″ – 5’11′ 25″ or 65cm
6′ and taller 29″ or 75cm

Please note, when you first blow up your new stability ball, inflate to around 85% for the first day, allow the ball to expand then on the following day inflate to around 95%

Job done, now for the work.
