For the image showing the groin please take a screenshot in Smooth Shaded view, instead of Texture Shaded.
What mophs are enabled - it may be that something is interacting with the pose. Are you working with limits on or off?
M7 and M7 body is enabled at 100%. I am working with the limits ON.
Would you be willing to post the pose, saved as a preset?
