As a new yoga student I loved a 'hands on' teacher! The feeling of a helping hand to enable my body to take a deeper twist or forward fold, ease my tight shoulders or position my body in a way I couldn't quite reach was just wonderful! Through these adjustments I could start to see how I would ultimately be able to do them on my own some day.
Adjustments can purely be verbal, for example, as a teacher I will tell my students how to roll their chests way from floor and open and lift their bodies and if possible those that can will benefit from such instructions.
Often in the early days of learning yoga, it is struggle enough just to try to get in the pose without having to fathom additional instructions and that's where the ‘hands on’ can be extra helpful!
I promise you though as the weeks and months (and in my case years!) roll on you will hear and be able to use these verbal adjustments to help.
