I think theres no need to go out and by big books of anatomy (they´re fiendishly expensive, the good ones 80$ upwards).
For body drawings either use a photo as a reference (sometimes a bit boring though), or get an anatomy poster (musculature or something like that), should cost no more than $10. Cause if youre into free drawing (no model) usually you cant go without some anatomical reference.

Go to your local library and check out books on anatomy if that''s what you''re after and don''t want to shell out all the money.
I grabbed one at my library last year and it was excellent. For the life of me I can''t remember the exact title right now, it was something like "Human Anatomy for Artists". It rocked. Next time I go I''ll see what the actual title and author was.
The best part about it was all the reference to how the body moves, which joints can rotate which direction, how the trunk of the body flexes. The shots of how the hands can be posed were awesome. It also shows every bone and muscle in the body.
Great reference if your library has it.

draw EVERYTHING. People on the train, your cat, your feet, a lamp, a chair, a spoon (like that guy in post your art here) what ever it all helps.

Yay to that. Draw everything. and whatever you do, try not to get discouraged. Drawing is about 5% talent and the rest is practise.
BTW: that was my spoon. And dont draw your feet just yet, hands, feet and faces are the most difficult things to draw....

have fun
