Trikonasana Part 2: Your Sacroiliac Joint

By: 
Ray Long MD, FRCSC

In this post, we will explore Trikonasana (Triangle Pose) with a cue that connects the forward leg psoas with the back leg glutes, thus stabilizing your pelvis.

First, take a quick look at the cue from my previous post on co-contracting the psoas and quads of your forward leg. Engage the forward leg psoas and quads and then add contraction of the rear leg gluteus maximus (and quadriceps) as shown below in figure 1.

The psoas creates a force that tilts the forward leg side of the pelvis (hemipelvis) forward (anteversion) while the gluteus maximus creates a retroversion force on the back leg side hemipelvis. You will feel how combining these opposing forces creates stability. Figures 2 and 3 below illustrate this concept.
