My DD was playing around with a Kvest the other day and there is a feature on there that shows the person how to hinge the hips properly. Apparently there are is a certain angle that the spine and the pelvis needs to be from one another, which I had no idea about. Anyway to achieve the proper hip hinge she had to get rid of the arch in the lower back and round her back while tucking her pelvis under. I have seen someone post about cat & cow in the past and the proper way according to Kvest at least is more in line with the cat and not the cow.

Interesting...I will have to read up on Kvest studies. I always like taking these units to my wife...to get approval for buying! She has a $200.00 limit mentality when it comes to my softball spending. Trying to convince her its 2018...the good stuff is expensive.
