I did a little bit Ashtanga (with a teacher) before going to AYBRC. Here is realised how incorrectly I was doing a lot of the postures, even the easier ones. I had a lot of corrections which may feel frustrating however, to avoid injury and to keep a daily practise, I needed to build up my strength, learn correct postures, focus on breathing, bandhas etc.
Radha and Prem will work with you to create a strong base and you will progress you once you are ready. Invaluable experience.
