Right-size the bout to beat all-or-nothing

Make the bout small enough that "no time" and "too tired" stop being excuses.

Why it works

The biggest barrier to movement is the perceived size of the commitment; an hour at the gym is easy to skip, two minutes is not. Shrinking the entry point removes the activation energy that kills the habit, and starting often leads to doing more — but the small version has to count as a full success on its own.

How to do it

1. Define a bout so small you can’t honestly say you don’t have time (e.g. one minute).
2. Let showing up be the win; doing more is a bonus, not the requirement.
3. Scale up only once the tiny version is automatic.

Evidence

Research on activation energy, self-efficacy, and small wins supports that reducing the cost to start drives consistency and builds the confidence larger change depends on. (mechanistic)

The "how small" threshold is a heuristic; the principle is lowering the barrier to start, not a specific studied duration.

Common mistake

Setting an all-or-nothing bar — a full workout or nothing — so on busy or low-energy days you do nothing, when a one-minute snack would have kept the streak alive.
