Excerpt from the article:
My own view on this is that I started Ashtanga at 43, unfit and overweight as many of you know. I worked hard at it, perhaps a little too hard given the condition I was in when I started but was lucky enough to avoid injury. I ended up practicing Primary, Intermediate, Advanced A and Advanced B, although the latter not really regularly enough to lay claim to it. Still most of the postures became possible.
So yes, Ashtanga is doable in your late 40s. I’m 50 now, the same age as Krishnamacharya in the old Black and White movie.
That said while you can practice a hard, fast paced Ashtanga into our 50’s and beyond we don’t have to practice it that way.
I’ve tried to show on this blog that there are many ways to approach your Ashtanga, it doesn’t have to be as fixed as it often seems. or how it gets mischaracterised in the media or misrepresented in some of the ‘look at me’ or promotional videos.
