S-T-R-E-T-C-H. Lay down on a carpeted floor and move. First whatever feels good. Then on my back for side-to-side head rolls, arms over head, legs lifts, sit-ups, bridges. Then side planks, and finally on stomach for push-ups, planks and some yoga positions. Every day is different. I think the resulting brain/cell oxygenation from rhythmic slow deep breathing is why it works.
