Every time you sit down to practice ānāpānasati—every sitting and every session—you must begin with step one, experiencing the long breath. It does not matter which step you were doing yesterday, today you must start again at the very beginning. Each session is brand new. From the long breath, move on to the short breath, and so on. Progress from one step to the next, completely fulfilling each step before moving on, until you come to the step where you left off the last time.
