8 XXX : girlsinyogapants

You aren't supposed to load your back and curve your spine at the same time. She is going up too high, although it's hard to tell because he ass throws the perspective of the shot off. :)
Looks pretty photoshoped, not only does the how much her spine curves look weird, but the weight plates just above her back are all distorted.

Hypnotic.
holy crap how many reps is she doing? i've drank to much tonight.
Is that good for your back?
Her ass is as powerful as a black hole, visually distorting everything around it.
Great form
