As the shoulders and upper back become more rounded, the muscles that stabilize the shoulder blades become weaker which can result in shoulder dysfunction and pain, neck pain and headaches. The abs are maximally stretched by the end of pregnancy which decreases their effectiveness and can result in what some refer to as a post-baby pooch.
Excessive curvature of the low back results in weak abdominals and glutes.
