Your body is amazing! It's supporting you through all that do, to the best of its capacity.
And sometimes your body has very limited capacity. It is giving you signs that you should slow down. Pains and aches start to happen. But maybe if you keep going it might just go away...
But it doesn't. It always comes back. It gets worse, or it shifts location or maybe your body just STOPS.

If you keep doing the same thing, you will get the same results.

Now that doesn't mean that you have to change everything all at once. But if you can make little changes or even just become more aware through listening, those are great beginnings.
I always hear: "Well I'm getting older, I'll just have to get used to it..." And it makes me sad, because the compensations your body has adapted to create the pain your in, shows its adaptability. 

You just need to learn how to work with your body!
That is where the Yoga Therapy Starter Kit will help you out!
