The number one strategy for learning how to draw figures is to actually draw figures. There really is no substitute for this. Figure drawing is best learnt by drawing figures, in the same way that learning to drive a car is best served by actually driving a car. Reading about drawing may help, as may talking to others about drawing, but none of this will make anywhere near as much difference as actually committing to paper your impression of a figure.
Just as it is no surprise that ‘practice makes perfect’, it should also be no surprise to learn that drawing figures in an optimum environment is better than drawing in less than perfect conditions. And just as learning to drive with an experienced instructor is preferable to going it solo, learning how to draw figures will be more effective if done with an experienced tutor.
Attending a life drawing class is almost certainly the best thing you can do.
In a life class conditions for practice are close to perfect. You have space, light, an easel, somewhere to sit your drawing materials. Everything is in reach in an environment set up for the job. You also have access to a tutor who can direct your learning, introduce new techniques, and offer advice on you drawings The tutor can help you to see some of the strengths in your work, and also some areas for improvement.
One other significant benefit of the life class is that it will have at least one model, a figure for you to draw. This benefit is not one that should be dismissed lightly. Have you ever tried to learn how to draw figures by asking a friend or spouse to sit for you? If so, you may know that this is not an effective method. They may not be very good at sitting still. They may want to chat to you, which can be distracting. They will almost certainly want to see the finished drawing which you may prefer not to show. The life model by contrast is a professional who will adopt and keep poses suggested by the tutor. The model will even take their clothes off so you can draw a real body, not a bunch of clothes with a head sticking out the top.
The combination of the right environment, an experienced tutor, and an experienced life model make your learning conditions ideal. With all that taken care of, all you need to do is to draw. Maybe try out a new technique for drawing. Maybe try a new medium, or different paper. All in a safe, non-distracting space.
