Start with a nourishing breath practice Nourishing breath | YoPO (yoponow.com) and then progress through the moving exercises, focussing on matching your movement to your breath. If you like, perform each movement 5 or 10 times, then rest and repeat. Experiment with making the movements bigger or smaller, faster or slower to comfortably build heat and become a little out of breath.
Finish by walking or marching on the spot for two or three minutes, swinging your arms and lifting the knees with each step. Again rest and repeat if you like.
