skinny-fit Japanese girl who trains a lot in boxing and goes for a low bodyfat percentage, so she's lean muscular in some places and really thin in others, especially her bony spine.
super lean lower spine if you like the EXTREME type where you can count every bump even when she's not bending over.
starting off with a pic where she covers her lower back and shows off her shoulder blades:

She used to have the smoother kind but leaned down and now has the really defined type no matter what position she's in.

I found that video and took some extra screen grabs of her shirt falling and every bump in her lower spine shows:

poor girl fell on her skinny back after that handstand and it almost looked like she fell right on that bony spine
a couple of pics of her spine sticking out under her shirt when she was stretching:
