Any good resources or tips for drawing figures? [View all]

I'm absolutely horrible at drawing/painting humans. I try to add silhouettes to my paintings and they end up looking like they were done by a five-year old. So I end up painting over them. I've seen paintings where with a few simple brushstrokes the artist adds figures. Any help would be appreciated. I know there are websites and tutorials out there. I just haven't been able to locate them.
