There are bajllion variations on pigeon pose. Full pigeon, one-legged pigeon, dead pigeon, active pigeon, king pigeon, etc.
Today it's Eka Pada Rajakapotasana...one-legged pigeon both dead and active. This pose is ridiculously difficult for me, thus I should be doing it every day. I try to hold a relaxed, passive version of pigeon pose for 3-5 minutes per side every night before bed.
However, this pose is tricky. It involves a strong external rotation in the hip joint, which has the potential to bring discomfort into the knee joint
I am always trying to learn more about the tightest part of my body:
This is a good video on how to do this pose from Livestrong:
