Okay so, I’m piss poor at tutorials but I do have at least one helpful hint that helped me when I was younger. Let’s grab a random picture of a person off google real fast for this exercise. I’d suggest either naked in as little clothes as you can find. 

Here I grabbed a lady in her undies in a  pretty basic pose. When I was younger I was taught to take something like this and draw shapes and stuff right over it.

By doing this you can more easily break the body up into shapes you understand, these shapes are like the building blocks to drawing anatomy. I’d do this with many different poses and body types to try and understand the shapes I’d need when drawing my own stuff and this is also the basics of all my drawing.

Once you understand where the shapes go and stuff you can apply it to your own style as seen above. I’d suggest using this to help you understand how to see the shapes of bodies and then be able to draw those shapes and over time with enough practice you wont even have to use all of them, you can just draw a body without using most of the shapes and sometimes none.

But drawing from refs is also super important, I’d suggest this site for figure drawing.
