When it comes to squatting, it’s extremely important to keep your lower back “Neutral” and not rotated. -This can be easily explained with the “Bucket Analogy”. -Think about your pelvis as a bucket full of water. The idea is that you want to keep the water inside and NOT let it leak forward or backwards. -If you excessively arch your back (anterior pelvic tilt) you will put a lot of stress on your lower back and your abs won’t be able to tighten up. Water will leak forward. ~ Berceste
