Posture Perfect or Not

In Ideal posture there exists optimal length-tension relationships between agonist, antagonists, neutralizer and stabilizer musculature. Ideal posture encourages maintenance of concentric joint motion and an optimal instantaneous axis of rotation. Bad posture can lead to a myriad of muscular imbalances including but not limited to what’s called an Upper Cross Syndrome where there is an imbalance between the flexors and extensors of the trunk. This is often seen in people who spend a lot of time hunched over a computer for most of their working day or who do a lot of floor abdominal crunches/classes without equal amounts of back extension repetitions to
counterbalance the flexion of the abdominals. As the abdominal muscles become stronger than their antagonists, the following imbalances in the body can be seen:

-Short and tight upper abdominals
-Depressed Sternum
-Forward head
-Increased thoracic kyphosis

lower half of the body in what is called a Lower Cross Syndrome which is a shortening of the lumbar erectors, ilipsoas, rectus femoris and tensor fascia latae with lengthening of the lower abdominal musculature, hamstrings, thoracic extensors and superficial cervical flexors – basically you look like you have a Donald Duck butt. This type of posture is usually seen in people who spend a lot of time working out in a gym setting with imbalanced programs. This can create a lot of problems for a person because the smaller stabilizer muscles of the body will get weaker so when you go to pick up your child or a grocery back you may find yourself doubled onto the floor with severe back pain or even a disc bulge.
