Like Gibberibberish asked, what learning process are you using?
Be aware that you won't improve much by just making a ton of drawings. You also need to acquire knowledge about the fundamentals (the basics) of what you're seeking to learn. Here's where books, classes and mentorship come into play. You need to learn what to think about and what to look for when you draw, and the tools to express your thoughts and observations.
It helps to learn how to draw first (how to control your lines, basic perspective, and how to draw simple forms in perspective) before you focus on a subject matter (like the figure in this case).
Having said that, it's also possible to learn the above using figure drawing as your vehicle if this is really the subject that excites you to draw. In that case, learn how the body is designed and works to keep itself balanced relative to gravity as it performs various actions. Understanding the figure's anatomy and natural rhythms come into play here.
