Timing of intensive and challenging tasks – self-regulation to support decision-making
Not all demanding work and training is equally beneficial.
The same task can lead to a peak performance one day and mere exhaustion the next.
The difference isn't about motivation, but rather about timing and managing your overall workload.
In this article, I discuss how to systematically schedule intense and challenging tasks and workouts—by using self-regulation to guide decision-making. The goal is not to avoid exertion, but to distribute it appropriately.
Let's go over:
Why is the mismatch between demand and current capacity one of the biggest factors contributing to the load?
how subjective feelings and objective metrics complement each other
How HRV, resting heart rate, and grip strength can help you time high-intensity workouts
Why a low HRV sometimes doesn't prevent peak performance—but why you shouldn't try to maintain it
This is not a workout plan or a list of time-management tips.
This is a decision-making model that helps you tackle demanding tasks when you can get the most out of them—and avoid situations where the effort is high but the benefit is low.
This isn't about collecting data just for fun
Self-regulation does not mean that everything is measured all the time or that individual figures are taken at face value. The purpose of these metrics is not to control actions, but to support decision-making when one’s own judgment begins to be clouded.
The value of the model is particularly evident when:
Recovery keeps stalling
Intensive work or training no longer leads to improvement
the workload piles up without you noticing
In this case, a simple "GO/NO GO" approach provides structure for regulating the overall load.
Who can benefit from this self-regulation model—and why
This model is particularly useful for people whose work or training requires sustained high performance. Typically, this applies to athletes as well as managers and experts engaged in demanding cognitive work.
The main reason is simple: subjective perception of fatigue often sets in last, while nervous system performance begins to decline earlier. People are able to compensate for fatigue for a long time, so their performance appears efficient even though their actual capacity is already declining.
Autoregulation provides an objective perspective on this. HRV, resting heart rate, and grip strength don’t tell you what to do, but they help you recognize when it makes sense to push yourself hard and when it’s better to save that effort for later. This way, the workload remains beneficial and doesn’t pile up unnoticed.
The essence of self-regulation: the level of requirements in relation to capacity
Stress isn't just about how much you do.
It stems primarily from what you're trying to do in relation to what your nervous system is capable of at that very moment.
Work of the highest quality produced while sleep-deprived is often:
underperforming
but unreasonably burdensome
In other words: you get top-level exertion without top-level results.
The purpose of autoregulation is to prevent this.
The vibe is important—but it’s not enough on its own
Subjective experience provides valuable context, but as stress levels rise, it can easily become distorted. Hyperactivity can feel like energy, and fatigue can sometimes be masked by a drive to perform.
That is why the feeling needs to be accompanied by an objective measure— not to replace the experience, but to help gauge the timing and overall workload.
HRV and resting heart rate – indicators of exercise trends
HRV and resting heart rate indicate the state of the autonomic nervous system over the past few days. They do not reflect current performance, but rather how much longer it makes sense to continue performing at a high level.
The following meters are read:
as trends, not as individual values
compared to one's own normal
If recovery continues to be poor for several days, you should limit high-intensity training and review your overall training load.
Grip strength – the nervous system’s capacity in this moment
Grip strength, as measured by a dynamometer, provides a quick snapshot of what the central nervous system is currently capable of. It reflects the nervous system’s ability to generate powerful and precise commands—in both physical and cognitive tasks.
Often, grip strength declines before fatigue is consciously felt, making it a useful signal to aid decision-making—not as a single fact, but as part of the bigger picture.
Overtraining and Poor HRV – Why Peak Performance Is Still Possible Sometimes
An overstimulated nervous system can momentarily produce extremely high performance, even if recovery indicators appear weak. This is evident, for example, in competitions and critical negotiations.
The problem isn't a single peak moment, but rather the company's ability to sustain this state over the long term.
The pressure helps distinguish sustainable capacity from a state of survival.
GO / NO GO – Physical Training
🟢 GO – maximum intensity
Maximum strength, VO₂max, intensity > 90%
RIR 0–2
🟡 GO – a developmental submaximal exercise
Basic strength, hypertrophy, basic endurance
RIR 2–5
🔴 NO GO – corrective actions
Recovery training, light aerobic exercise, rest
GO / NO GO – cognitive task
🟢 GO
Strategic decisions
Negotiations
High-stakes thinking
🟡 GO
Preparation
Analysis and design without locking
🔴 NO GO
Routines
Administrative work
Recovery and breaks
RIR and VBT – supporting subjective assessment
RIR (reps in reserve) is a subjective way to assess training intensity: how many more reps you could have done before complete exhaustion. It works well in everyday life for regulating workload and is based on the trainee’s own experience and body awareness. Challenges usually arise in borderline situations—with heavy loads, uncertain recovery status, or overexcitement—when subjective assessment can begin to be distorted.
In such cases, measuring lifting speed (VBT) can serve as an objective indicator. VBT meters measure how fast a barbell or other load moves during a lift, which reflects instantaneous power output and neuromuscular activation. If a familiar load is moving noticeably slower than normal, the actual load is likely heavier than it feels.
From the perspective of self-regulation, VBT does not replace the RIR assessment but complements it within the workout. When used together, they reduce misjudgments and help ensure that training intensity is more often in the right zone—without turning the workout into a technology project.
Summary
Top-level performance isn't about constantly pushing yourself to the limit.
It's about well-timed intensity and a controlled overall workload.
Self-regulation is the ability to adjust your expectations to what your nervous system is currently capable of. When this balance is achieved, stress is reduced, progress is accelerated, and the right conditions are created for peak performance—both in sports and in demanding work.
