As a yoga teacher, I get lots of questions about the alignment of poses. Should I throw my head back in upward facing dog? Should I reach for my feet in a seated forward fold? Should I squeeze my quads and lift my kneecaps in tadasana? My best answer to questions like these is usually it depends on your approach to your practice. From my perspective, there are two versions of nearly every yoga pose: the traditional version and the biomechanically-updated one.
