This final compulsory pose really shows the abs better than any other.
The Ab and Thigh Pose is the last in the bodybuilding exercise analsysi series (Quicktime, 1MB; Google Video streaming flash). Some may say that it is the most aesthetically pleasing of the poses because it shows off the abs so well.
As you can see in the video I enter the pose by setting my feet. I begin by placing my left foot forward and only setting the ball of my foot on the floor. I imagine that I am trying to push my left foot through the floor. This downward push completely flexes the quad. My right leg remains slighty bent and contracted the entire pose. As I finish setting my feet I begin to enter the rest of the pose.
I bring both arms away from my sides and sweep them over my head. I then clasp my hands behind my head and begin to exhale completely. Exhaling all air allows a full contraction of the abs. By crunching down slightly (as in performing an abdominal crunch on the floor) I can further contract the abs and enhance the look of the pose. Be sure to not crunch down too far as this will hide the abdominal development. Also remember to contract the lats and biceps because they are visible in this pose as well.
This pose shows full quad and ab development in addition to calves and lats.
