Working quickly does not mean working recklessly. Kind of like how a golfer will make a few practice swings before connecting with the ball. I usually make a few practice strokes in the air before committing to the paper. Do not draw lines just for the sake of drawing lines. Try to draw every line with some kind of purpose. This follows the general art guideline of working general to specific. Once you have done that, you can go over and render with more detail and tone. Try to capture the essence of the pose before you try to render form. Regardless of any time limits, the first thing you should do in gesture drawing is to capture the essence of the pose. But as I progress, my hands and eyes warm up and everything starts to flow. My hands just do not do what my eyes want them to do.
It is great for warming up your hands. I often find my first drawings in a session are rigid and tight. Gesture drawing is a very efficient way to hone your drawing skills without having to commit a significant amount of time to it. It will indirectly benefit your painting skills. Drawing is the backbone of painting, so do not overlook it. You will learn how the body moves and is connected. It really gives you a feel for the form and anatomy of the human body. You will gain a better understanding of form and the human anatomy. This is one of the main reasons people practice gesture drawing in the first place.

You will learn how to draw more instinctively. You cannot afford to think too much with gesture drawing, so you need to rely much more on instinct. The more problems you encounter, the more solutions you will develop. You will see noticeable improvements in your drawing within a relatively short period of time. This is because you are working relatively fast and will encounter so many more problems than if you were just doing one large artwork. If you make a mistake, then just learn from it and move on to the next drawing.
You should not be doing any erasing in gesture drawing. You do not have to worry about making mistakes.
