I remember the first time that I tried Eka Pada Koundinyasana II in class, and I just kept thinking “What in the world?!” It took me a lot of practice and trial and error to figure out the intricacies of the posture. I am sharing with you the way that really helped me to get into this posture. I hope this helps!
Begin in Runner's Lunge
Bring your arm underneath your leg, so your knee is as close to your shoulder as you can
Keeping your knee close to your shoulder, bring your hand to the inside of your foot and begin to bend your front leg. Once your front foot is off the ground, slowly begin to shift your weight forwards you bring your back leg up high. Remember to keep your gaze forward and shoulder level.
If you are still feeling good, begin to straighten your front leg. Hold for a few breaths, and step back.
