I try to do five minutes of pranayama in the morning or before bed. If I’m energetic, I just sit down and do it. If I’m exhausted, I make my way into legs up the wall and rest there a few minutes. Then I begin some gentle pranayama. If it’s morning, I might sit up afterward and do more vigorous pranayama if I have time, and end with a savanasa (corpse pose). If you don’t have five minutes?
