For me, routine and discipline. Walk at lunch every day. Monday, Thursday and running days. Tuesday, Friday are push-ups; Wednesday and Saturday are weights. I have a paper day-calendar that I mark when I work out; helps in case I miss a day and need to reschedule or get back on track. Seeing the history also gives me a warm and fuzzy "filling XP bars" feeling. I use sheets of graph paper clipped to clipboards for the push-up and weight workouts so I can track the weight / number of reps I did. When I worked out at the gym I used to use the "Notes" app in iOS for this. I tried a number of workout tracking apps but was never satisfied with them; too hard to see history or record an unscheduled change.
