I'm a 200h Hatha & Vinyasa yoga certified instructor. I suffer from RA for about a decade and yoga is what made the big change in my life. Thank God i do yoga for about 20 years and my body reacts better than my condition allows. I'm 49 years old and i was told that in my 45's i would be on a wheelchair. I do yoga, the full consept, not only the asanas and i keep going .
