Opening scene
Tuesday evening. Practice is on the calendar.
But you went to sleep at two thirty in the morning, you carried a difficult conversation through the whole day, and right now there's tension in your shoulder left over from yesterday.
Two voices are talking in your head. The first says, "Don't practice today, be kind to yourself." The second says, "If you start with this excuse, you'll never do it again."
Both sound right, and both are asking the wrong question.
The right question isn't "should I practice or not." The right question is this: with the body I have today, which version should I do?
This lesson is about answering that question in two minutes, based on information instead of guesswork.
What this lesson covers
First we'll talk about why the plan stays fixed, why the body stays variable, and the bridge between the two. Then we'll open up the four indicators: energy, stress, pain, and sleep. After that you'll see how to read these four, which one behaves differently from the rest, and why a coarse scale works better than a fine one. Then we'll build the decision rule that takes you from the indicators to a version of the practice. With sixteen examples, you'll read how the decision gets made on real days. By the end of the lesson you'll have written your own check-in card and be able to decide in two minutes which version to do that day.
Starting point
You make a plan, and the plan is fixed. It sits on paper and doesn't change.
The body isn't fixed. The same person isn't the same body on Monday and on Thursday.
Without a bridge between the two, one of two things happens. Either you carry out the plan regardless of the body, which means raising the load on bad days. Or you treat the body as an excuse and drop the plan, which means never practicing at all.
Here's the bridge: the plan itself doesn't change; the version of the plan changes.
Think of it like a car's gears. Staying in a high gear on a hill strains the car; shifting down isn't giving up on the trip. The trip continues — only the torque changes.
Now the question is: how will you tell which gear you're in today?
The answer isn't a guess. Guessing shifts with your mood in the moment; you do too much on a day you feel good and too little on a day you feel bad, and either one can have nothing to do with reality. Instead, we'll look at four indicators.
Mechanism
The four indicators
Why these four categories? Because two of them tell you the body's capacity right now, and the other two tell you where that capacity is coming from.
The first indicator is energy. How much work does your body have in it right now? Don't confuse this with "do I feel like it" — wanting and capacity are separate. Some days you don't feel like it, but your energy is there.
The second indicator is stress. Mental load directly affects the quality of movement. On a high-stress day, balance poses get noticeably harder and the breath shortens sooner. This isn't a weakness; it's a predictable state, and what's predictable can be planned for.
The third indicator is pain. This one works differently from the rest, and we'll take it up separately in a moment.
The fourth indicator is sleep. Yesterday's sleep duration and quality determine today's capacity to recover. A heavy practice done after a poorly slept night asks for a longer recovery window than the same practice done well rested.
Why a coarse scale works better
You could score each indicator from zero to ten. But there's a better way.
Use three steps: low, medium, good.
Here's why: on a ten-step scale, you can't reliably tell the difference between a six and a seven. A difference you can't tell apart becomes noise once it's on the record. Three steps, though, are distinguishable and enough for the decision.
The second reason is more practical: a ten-step scale requires thinking, a three-step scale doesn't. A check-in that requires thinking gets skipped on a tired evening.
Why pain is different
Now let's turn to the third indicator.
Energy, stress, and sleep get averaged together; if one is low and the others are good, the day is still workable.
Pain doesn't enter the average.
But not every pain. A distinction is essential here.
A widespread, dull tightness that's similar on both sides and left over from yesterday's work is generally a workable state; light movement usually eases it. By contrast, a sensation that's sharp, concentrated at a single point, worsens with movement, numbing, or spreading isn't worked through. This second group moves you to the rest version, and if it persists, it calls for a professional opinion.
Let's be clear about this: this course doesn't make medical diagnoses. We're not discussing what the pain is, but what to do that day. For pain that's new, unexplained, or that doesn't go away, the place to turn is a health professional, not a lesson.
The decision rule
Now let's tie the four indicators to a decision. The rule has to stay simple, because a complicated rule doesn't get followed.
First, look at pain. If it's sharp, spreading, numbing, or new, take the rest version — and a professional opinion if needed. The decision ends here; the other indicators aren't checked.
If the pain isn't that kind, look at the other three. If all three are good or medium, take the full version. If one is low, take the reduced version. If two are low, take the minimum version. If all three are low, take the minimum version or rest — both are correct answers, and the choice is yours.
Decide up front what you'll reduce in the reduced version, too. There are four dials: duration, intensity, range, and pace. The best first move is usually lowering duration and pace; cutting the range is usually unnecessary.
Reading the examples
Master layer
Now let's go somewhere a little more subtle.
A moment ago, I described the four indicators as equally weighted. In reality, that weight varies from person to person, and you can only find your own weighting by keeping records. For some people, sleep is the dominant indicator; one poorly slept night pulls the other three down with it. For others, stress is dominant. After three or four weeks you'll recognize your own dominant indicator, and that one indicator gets more of a say on its own.
The second nuance is self-report's directional bias. People tend to overestimate their capacity on days they feel good and underestimate it on days they feel bad. In other words, the indicator exaggerates the real difference. Knowing this adds a correction to the decision: don't exceed the plan on a day that looks very good, and don't give up entirely on a day that looks very bad.
Third, the check-in itself is an intervention. Someone who spends two minutes looking at their body every day reads their body better by the third week. This isn't a side effect of the measurement — it's one of its most lasting gains, and no pose can teach it.
Fourth, and the subtlest point: the daily check-in isn't a permission slip. Its purpose isn't to produce a legitimate way of saying "it's fine if I skip today," but to adjust the load correctly. What separates the two is how often the rest version gets chosen. Resting a few times a month is normal; resting three days every week says the check-in has stopped being a decision tool and turned into an escape tool, and at that point, what needs reviewing isn't the indicators — it's the plan itself.
Common mistakes and misconceptions
Common mistakeFirst mistake: if I feel bad, I shouldn't practice.
This narrows the choice to two: do it fully or not at all. But there are two more versions in between. A bad day usually means not "don't," but "reduce," and a reduced practice usually feels better than not practicing at all. Pain alone is the exception to this rule.
Common mistakeSecond mistake: if there's pain, I'll just go light.
This sentence is dangerous because it doesn't account for the type of pain. For a widespread tightness left over from yesterday's work, light movement is reasonable; for a sensation that's sharp, spreading, or numbing, even light movement isn't appropriate. It's the quality of the pain that decides, not its intensity.
Common mistakeThird mistake: the daily check-in is a waste of time, I already know how I'm doing.
You know, but you don't remember it consistently. The check-in's real job isn't producing information in the moment; it's letting a pattern emerge when you look back after three weeks. A single record has low value; fifteen records have high value, and fifteen records only come from filling it in every day.
Common mistakeFourth mistake: if the indicators are low, that day is wasted.
A day spent doing the minimum version carries almost the same value, for the habit, as a day spent doing the full version. No capacity gain happens that day, but continuity is preserved, and what determines capacity gain in the long run isn't individual days — it's the weeks that don't get missed.
Practice
Keep in mind
The plan is fixed, the body is variable; what connects the two is choosing a version, and all four versions are part of the plan.
Four indicators get read: energy, stress, sleep, and pain. The first three get averaged together; pain doesn't enter the average.
Pain is a veto indicator, but not every pain; sharp, spreading, numbing, or new pain stops you, while widespread tightness left over from yesterday's work usually doesn't.
A coarse three-step scale works better than a fine ten-step scale, because it's distinguishable and doesn't get skipped.
A single day's check-in produces a decision; several weeks of check-ins fix the plan.
Bridge to the next lesson
Now you know which version to do each day. But there's still something you don't know yet: how is your body actually moving today? In the next lesson, we'll observe that. Notice I said observe — not test. That difference is the whole subject of the next lesson, and also the most common mistake.
