I love Yoga.
The Yoga practiced in the U.S. is a westernized version.
As a senior, Yoga helps keep me flexible, plus, there are many other benefits.
Yoga saved my life.
After a bad fall, I had difficulty walking. After taking several Yoga classes and practicing at home (with medical approval), my flexibility improved a lot. My walking gait is smoother, my back pain is less.
Plus, I like the emphasis on breathing and good posture.
These are my favorite Yoga poses / Asanas:
Mountain pose / Tadasana
Standing Forward Pose / Uttanasana
Corpse Pose (Supine Full Stretch) / Shavasana
Supine Butterfly / Supta Baddha Konasana
Shoulder Blade Pinch
Lower Back Press
Supine Twist Pose / Supta Matsyendrasana
Supine Knee-to-Chest / Apanssana
Knee-to-Chest Roll / Pawan Muktasana
Ab Crunches
Seated Butterfly / Baddha Konssana
Seated Forward Fold / Paschimottanasana
Twisted Sage Pose / Marichyasana III
Cat / Cow Pose / Marjaryasana
Baby Pose / Garbhasana
