See the title there? That's my yoga philosophy.
It shouldn't be complicated, but for many of us, it is. If you were to believe the mainstream yoga-related media content, yogis are all thin, white, young, able-bodied, naturally flexible, and so on. There's nothing wrong with being any or all of those things, of course, but more importantly, there's nothing wrong with NOT being those things.
I'm fat. I embrace that term as a neutral descriptor, because that's all it is. The same as you could say I'm a redhead, I have freckles, or I'm pale, you can say I'm fat. And because of that, many would want me to think I shouldn't be doing yoga. But that's not true.
I want to do yoga, so it's for me. It's also for you, if you want it to be.
Maybe you've never been told you're OK as you are. If that's the case, I am so sorry the world has failed you, but I'm going to say it: you are OK exactly as you are.
You're not too fat to do yoga. Or too old, or too disabled, injured, inflexible, "out of shape" (I don't like that term), or anything else. Maybe you won't be able to do certain poses, or maybe you'll need modifications, or maybe your yoga will be entirely inside your mind, but it doesn't matter. You can do some form of yoga no matter what.
Now, I'm not going to be that person who tells you that if you have a chronic condition, yoga will cure it. Not at all. And not everyone has to be interested in yoga. That's perfectly alright. (Though I'm assuming if you're reading a yoga blog, you have at least a passing interest.) But if you want it, it's there for you.
