Before heading to the gym for a workout, plan out your workout in detail (what exercises, in what order, how many sets, how many reps) and preferably carry a piece of paper with the workout written on it. This leads you to getting more done in less time. But more importantly, this prevents decision fatigue from draining your willpower; and you need willpower in large quantities to finish your workout.
