Hello 
Lavenderblue here. I am 36 and I have been practicing yoga on and off for years now, but have recently become inspired to get back into a proper, regular practice. I am a big girl so find it more difficult to do some poses but, I will find away.
Very pleased to be here though.
Hi Lavenderblue,
I have a married couple in my class, both of them very large (length wise and sideways), and we have designed a special set of asanas for them to help them. This they practice at home as well as once a week at class. If one is careful and listen to your body, there is no reason why even larger people can’t do it. Ask you yoga teacher to help you to design a set for you, it will help you, because them you can do them in the privacy of your home as well.
Welcome to the forum, trust you will find the answers and inspiration here you need.
