My favourite style of yoga is Iyengar - I am concerned with getting accuracy in my alignment and so this style of yoga seems best for me. I think for someone like myself with postural issues that it is safer to stick with iyengar for this reason - which is a shame as I love vinyasa yoga but I am concerned that I haven't got enough time to check my postures are correct before I move to the next one. How can I prevent injury this way? I am simply a student and not an expert so I wonder how teachers deal with these types of issues?
