) Right now i'v stuck with the upper legs. If you look on some youtube fitness videos with squats, you'll notice there are a lot of stuff going on in that area, but its very hard to catch an individual muscle shape change and shift. Also there is this yucky thing on the outer thigh, called "iliotibial tract". Sometimes it strangles underlying muscle in one area, sometimes in another, sometimes with its margins, sometimes with its middle. And also it slides over. I cant figure out the logic, and it freaks me out... arhhhh!! ))
So any good references or explanations of that area would be great! Tnx)
