This is from the same 1938 newsreel that shows Krishnamacharya demonstrating yoga. Here we see a young Iyengar (still alive, well, and doing yoga, BTW) doing advanced poses that constitute the advanced A&B astanga series. This is obviously well before Iyengar dropped the vinyasa aspect from his practice and rebranded it as \"Iyengar Yoga\", putting greater emphasis on allignment. asana, ashtanga, astanga, fitness, health, india, iyengar, jois, pranayama, yoga
