Everybody can practice Ashtanga Yoga.
Pattabhi Jois said this often: the young, old, very old, sick, weak and strong can all do Ashtānga yoga. The only people who cannot practice Ashtānga Yoga are lazy people! Dedication, Determination, Discipline and Devotion are required.
NOW yoga is here for you. Whoever you are, wherever you are at, whatever your condition, yoga will meet you there, in this moment.
NOW yoga can begin.
