This weeks class works towards the backbend vrschikasana (scorpion pose). The shoulder action that is required for this asana is explored initially in sirsasana, with your hands holding a block placed behind your head. This action is further developed in dwi pada viparita dandasana. Eventually vrschikasana is linked with pincha mayurasana, and then practiced with the aid of a chair. This energising class is intended to challenge experienced back benders. In addition to improving your backbends, the poses will also be great for opening your shoulders.
