While the two pictures are not identical in posture / lighting / clothing / tanning, you can clearly still see a significant difference.
3.5 years of twerking can really make a difference in your butt and thighs! Size-wize they're about the same, but the legs are a lot firmer and the butt sits higher and rounder. Just ONE of the benefits of twerking (and definitely not the most important).
I teach twerk every Wednesday and Thursday in Tel Aviv. Contact me for inquiries regarding those classes, or for booking me for workshops anywhere in Europe.
