Everyone started out not knowing where to begin. Even the masters had to do figure drawing, and in the beginning they had no idea where to place their charcoal on the paper. Getting used to figure drawing (no matter what the pose) is something that will come with experience (and certainly far past the first 10).
Many start with the head. However, I feel the chest is the best place to start as it is the main piece of body with everything sticking out of it. Best thing to do is start with the chest (or head if you feel it is better for you personally) and block out a very rough and light skeleton of the figure. You’ll get faster at this the more you do. Once you have the body mapped out then you start in with the details. Focus on convex and concave lines. Really make your figures fluid… that is what brings them to life 
It helps to draw from the same model when you are first starting. I am going to link to a couple of deviantart links that you might find helpful.
Stock site. Same woman, thousands of poses. Great for gesture drawing: http://senshistock.deviantart.com/
What I do is save a whole bunch of pictures to a folder. I then set my desktop screensaver to Photos and select that folder. Adjust the time of each slide as necessary. But it works exactly like a real figure drawing class does. Only giving you 10 seconds, 3 minutes, 15 minutes, 30 minutes, etc. to draw your figure. I really like the 10 second ones. It’s frustrating at first, but it really helps you grasp the full figure quickly before being forced to the next pose. If you’re not finished with that pose, forget it, move on to the next. No big deal. Just keep working!
But… just in case, here is a link that might be more of what your post was referring to.
