Stretching and light calisthenics when I wake up. No need to be fancy or intense, just touch your toes, butterfly, cross arm stretch, along with a set of pushups and squats. It also helps to pay attention to your posture, and adjust chairs/monitors to prevent slouching (maybe visit the optomotrist or increase font if you're leaning a lot).
