How to start a cycle-aware training log

The best training log is the one you actually keep. If you are just getting started, you do not need a spreadsheet or a complicated system. You need something you will still be doing in three months.

Step 1: log the session, not the theory

Write down what you did: the activity, and a couple of numbers that matter to you, like the weight and reps on a main lift, or the distance and pace of a run. That is enough. You are building a record of reality, not filling in a form.

Step 2: let your phase come along for free

The magic of a cycle-aware log is that each session gets tagged with your cycle phase automatically. You do not add anything extra. Over time, that quiet tag is what lets a pattern appear.

Step 3: be patient, and be honest

One cycle tells you almost nothing. Three or four cycles start to tell a story. And sometimes the story is “there is no clear pattern here,” which is a perfectly good answer. Rest days count. Off days count. The point is not to perform for the log, it is to see yourself clearly.

Step 4: read your own chart

Once you have a few cycles in, look at how a lift or a run moves across your phases. If a real pattern shows up, you can plan around it. If it does not, you have learned something too: you can train by feel instead of by rule.

That is exactly what Lunia does for you. Log a session in a few taps, and after a few cycles it shows your real pattern, with the uncertainty left in, so you never mistake noise for a signal.
