The Law of Reverse Effort is a mental model for situations in which applying more force begins to reduce progress. The mechanism is not laziness; it is the removal of counterproductive tension. At maximum perceived effort, an athlete may tighten muscles, a thinker may lose perspective, and a worker may confuse motion with output. Lowering effort to a controlled level—illustrated by Carl Lewis’s 80 percent rule—can restore fluid movement, awareness, and timing. The practical test is empirical: identify an area where force is degrading results, deliberately relax, and compare the output. The model also encourages selective intensity. Like Lionel Messi scanning the field before a decisive burst, a high performer can conserve attention and deploy it where the moment has disproportionate value.
Origin
Bloom connected Aldous Huxley’s reverse-effort idea with Carl Lewis’s 80 percent rule and Lionel Messi’s selective bursts of effort.
Core principles
- 01More effort does not always produce more progress
- 02Excessive strain can degrade the mechanism needed for performance
- 03Relaxation can create the conditions for speed and precision
- 04Save maximum effort for the moments where it has leverage
How to run it
- 1
Spot reversed progress
Find a task where increasing effort, speed, or urgency is coinciding with worse results.
Pro tip Look for physical tension, narrowed awareness, repeated errors, or constant motion without movement.
- 2
Name the interference
Identify how forcing the task disrupts performance, such as tightened movement, shallow thinking, or attention spread across low-value work.
Watch out Do not assume every poor result is caused by excessive effort.
- 3
Reduce to controlled effort
Perform the task at roughly 80 percent intensity, prioritising looseness, awareness, and clean execution.
Pro tip Use 80 percent as a practical experiment, not a universal precision measurement.
- 4
Compare the result
Assess whether the lower-effort attempt improves speed, quality, clarity, or consistency.
Pro tip Judge output, not how impressive the effort looked.
- 5
Deploy intensity selectively
Conserve energy during low-leverage periods and commit hard when a decisive opportunity appears.
Pro tip Use quiet periods to scan, think, and create space.
Watch out Selective effort is not permission to avoid the moments that genuinely require intensity.
In the wild
Bloom explained that sprinter Carl Lewis found he ran fastest when aiming for 80 percent effort. Trying to force 100 percent made his body tense and slowed him down, while reduced strain allowed faster movement.
→ Lower perceived effort produced greater actual speed.
Lionel Messi often walks slowly while scanning the field, then accelerates at the exact moment and angle required. His apparent inactivity preserves awareness and lets him concentrate effort where it can change the play.
→ Selective intensity creates better positioning and decisive execution.
Common mistakes
Using the law to excuse low effort
Reverse effort applies when force itself is causing interference, not whenever a task feels hard.
Optimising visible busyness
Constant activity can resemble commitment while producing no forward movement. Measure results instead.
Is it for you?
Best for
Performers who tense up under pressure or stay constantly busy without producing meaningful progress.
Not ideal for
Tasks failing because of insufficient preparation, skill, or baseline effort.
From the transcript
“sometimes uh you put in more effort and it actually reverses your progress and so what you need to do is actually relax in order…”
“sometimes in order to speed up you need to slow down you actually need to like lower the effort level a little bit so that…”
