Myth 4: In Tree Pose, your lifted knee should point directly to the side.
In Tree Pose, the common tendency is to turn the knee to the side and for brevity’s sake that might be a simpler way to cue the pose. However, the anatomical reality is that because the acetabulum (the part of the pelvis that the femur bone inserts into) faces slightly forward, it’s impossible even with greatest hip flexibility to turn your knee to the side without moving your pelvis, which also rotates the spine. Instead in Tree Pose, try keeping the pelvis squared forward and moving the knee as far to the side as you can without letting the pelvis change. That will keep the spine, the hip, and the standing leg squared forward too.
