In your body, sets of muscles attach to a joint to give them stability and align your body in the most efficient manner. This is similar to riding a bike, where the control and balance of your bike frame is provided by the synchronisation of the handlebars.
When one side of opposing muscle is stronger than the other side, it leads to muscle imbalance. Suppose, if you are regularly using one side of muscle more than the other, it will become stronger- but shorter and tighter. On the other side, the opposing muscle will become weaker, longer and loose. The disproportion in strength of the muscles around the joint, leads to muscle imbalance in turn eventually causing bad posture.
Certain factors which can contribute to and create muscle imbalance are:
Level of activity
Things done on a daily basis
Amount and type of exercise
How you sit, stand and walk
It is seen that people who have a sedentary lifestyle or actively working out, are more prone to develop muscle imbalance.
