Query: AMAZING Yoga Instruction

I have been doing yoga on and off again for years. I am now a committed enthusiast of yoga. This is one of my first yoga instructions and I have tried others only to find myself in severe pain after the fact. His instruction is very complete, after you have done it a few times, you rarely have to look up at the TV, which hurts your neck anyways. He also demonstrates modified poses for the less flexible. I have found his techniques are wonderful and low impact. I feel amazing and pain free when I'm done. I highly recommend this instruction for beginners and novice. A great workout without side-effects.
