I've been seeing a LOT of tight psoas muscles lately! This muscle attaches to your lower spine and to your thigh bone. If it's tight (sitting too much?) it pulls your lower back. It's ONE of the common causes of lower back pain! If you can stretch this regularly then your lower back may feel a lot better! (makes your tummy look a bit flatter too.) ;)
Continuing to assume an anterior tilt on one side we will almost always want to bring length into the front of the hip and lengthen the hip flexors. This can be anything from a simple lunge to a supta virasana. Feel free to use any other postures that you know put length into these tissues. If the gluteals and lower back are involved then make sure the student isn’t over tightening their buttocks in their up dog or other back bending...
