Need for speed: Speed drawing pose practice

I've always thought that speed is a skill that is very important to comic and manga artists. Meeting deadlines and also being able to continuously create new ideas isn't something that can be done if you spend 30 minutes perfecting each character's pose. This is my problem.
To remedy it, I've been trying to make the habit of practicing 45 second drawings on Posemaniacs.com It's a great website that I was introduced to in college for my drawing 101 class.
I've been doing sets of 10 as recommended by the website. Within only one week I can already see improvement in the completeness and structure of the poses.
It's an exercise that I recommend any budding artist add to their regimen. It only takes about 7 minutes for a set of 10, 45 second drawings, and onlly 5 minutes if you do the 30 second drawings.
That will be the next step up for me.

My first bout.

Today's practice.

You can tell that the drawings are much more complete.

I'm very happy about it. I hope if you've never heard of posemaniacs you will check it out. It's a great resource.
