While groin pain as a concept is very real, the groin itself is an area as opposed to a specific muscle. Some anatomists and anatomy books refer to the inner thighs, or adductors, as the groin, while others include the psoas, the transverse abdominus and others.
Any way you look at it the pain is usually in the area of the hip crease where the leg and the pelvis meet. The concept of groin pain can include the inguinal ligament, the IT band, the psoas and more. I refer to the groins a lot in yoga class in terms of how they should feel and look.
We want deep groins, a phrase that doesn’t always make sense. I know that because I am often looked at with a blank stare when I say “deepen the groins”. As a yoga teacher I am very often getting my information by reading the way clothing fits on a body, most importantly the wrinkles that clothing makes.
Very often, the way people stand forces the thigh bones forward pulling the pelvis into a tucked position. When this happens the fabric of pants usually gets pulled tight eliminating wrinkles. When you deepen your groins wrinkles will magically appear. We want wrinkles.
The way out of groin pain as well as most other pain is to change your posture and walking patterns. Change the way you walk and stand and say goodbye to groin pain for good.
