Just yesterday, I watched online an Ashtanga Primary Series class with full vinyasas between poses and half vinyasas between right and left sides of a pose. A full vinyasa in the context of Ashtanga yoga is Sun Salutation A. A half vinyasa, a.k.a THE vinyasa in popular yoga jargon, is the transition as such: (plank)-chaturanga-urdva mukha savanasana-adho mukha savanasana.
This class lasted for two hours and everybody was really really tired at the end. In the normal practice, when we are not as ambitious, we do half vinyasas between poses and between sides of each pose.
After I posted the article on adho mukha svanasana, I came across a Facebook status update by Diane Bruni that she called The Hand Rant. In the rant Diane Bruni challenges the generally accepted alignment principles of the yoga hand. She first explains how she was taught to align her hands in Iyengar yoga, which is how we normally teach: press down all four corners of the hands and later argues that this may not really be the best alignment to protect the wrists. Bruni suggests, instead that one should release the knuckles and let them form the natural dome of the hand. Here is what she means:
As someone with very fragile wrists and generally very rigid joints, I am always aware of my hands and wrists during my practice. I get the occasional wrist pain in upward facing dog and other arm balances. The alignment of the hands when the hands are to bear weight, of course, has a lot to do with how the weight of the body is distributed. General tendency amongst new beginners is, to lift the hand off the floor and leave the wrist to carry the entire weight. This is no good for the wrists. So, we tell them to press the entire hand down. This i.e. turning the palm down also pronates the forearm and directs the weight from shoulders down through the wrist to the hands. Bruni’s suggestion makes sense because it leaves enough room for shock absorption when more weight is loaded upon the hand.
