Question
Protect repetition frequency before increasing intensity
A harder habit performed rarely may be training difficulty rather than training automaticity.
When it fits
- A new habit becomes harder so quickly that repetitions begin disappearing from the week.
When to avoid it
- Some training programs intentionally require recovery days; frequency should match the behavior's purpose rather than 'daily' as a default.
A question to ask
How often is the behavior actually occurring? · Did the last progression reduce repetition frequency? · Can I keep the cue but scale the behavior down on difficult days?
Why it matters
The review identifies repetition frequency as an important determinant of habit strength. During the formation phase, protect the opportunity to perform the behavior before increasing load, duration or complexity. Progress when the higher difficulty does not destroy the repetition pattern.
An example
Keep a shorter walk on a busy day rather than turning a new walking habit into an all-or-nothing 60-minute requirement.
Check your result
Progression does not cause the behavior to disappear from its stable context.
Keep this limit in mind
- Some training programs intentionally require recovery days; frequency should match the behavior's purpose rather than 'daily' as a default.
