I highly recommend looking for ways to incorporate even short yoga routines into your daily life. It can greatly help with muscle aches and with your ability to focus and sleep.
My ideal is an hour each morning, but I do strive at least to do ten minutes if I can't get that in.
You can do easy simple things even at your computer. Imagine you are making a golden halo with the top of your head, in a clockwise direction. Then reverse.
