Training without tracking is like driving without a speedometer - you have no idea how fast you're moving or whether you're actually heading in the right direction. A training log is the single most powerful tool for ensuring consistent progress. It doesn't need to be complex - simplicity ensures you'll actually use it.
The minimum information to record for every session: date, exercise name, weight used, sets completed, and reps per set. Some lifters also record rest periods, perceived exertion (RPE, rated 1-10), and notes about how the session felt. This data shows you exactly where progress has occurred and where you've stalled, making programme adjustments data-driven rather than guesswork.
App options for Australian lifters: Strong (simple and popular), JEFIT (more comprehensive), or even a basic notes app. Many advanced lifters prefer a physical notebook for training logs because it's less distracting than a phone in the gym and physically satisfying to fill. Review your log weekly to identify stalled lifts and plan the next week's progression. A stalled lift means it's time to change something - rep range, exercise variation, or rest period. Without a log, you'll repeat the same workout over and over wondering why progress has stopped.
