Core Stability
What is "core stability"?
"Core stability" describes the ability to control the position and movement of
the central portion of the body. Core stability training targets the muscles
deep within the abdomen which connect to the spine, pelvis and shoulders,
which assist in the maintainance of good posture and provide the foundation for all
arm and leg movements.
What are the benefits of core stability training?
Quite simply, good core stability can help maximise running performance and
prevent injury. Power is derived from the trunk region of the body and a
properly conditioned core helps to control that power, allowing for smoother,
more efficient and better co-ordinated movement in the limbs. Moreover,
well-conditioned core muscles help to reduce the risk of injury resulting
from bad posture. The ability to maintain good posture while running helps
to protect the spine and skeletal structure from extreme ranges of
movement and from the excessive or abnormal forces acting on the body.

Things to remember when doing core stability exercises:
1. Do not let your whole stomache tense up. If your upper abdominable muscles
"bulge" outwards it means you have cheated by using the large rectus abdominus (six pack)
instead of the transversus abdominus (lower abdominals).
2. Do not brace your lower abdominals too hard; a gentle contraction will suffice.
You are trying to improve endurance rather than maximum strength. Only
clench them about 50%.
3. Do not hold your breath as this is a signal that you are not relaxed. You must
learn to breathe normally since you will need to breathe when you are running!
4. It is a good idea to do core stability as part of your cool down after running, or
on a cross-training day.
