Anchor movement to existing routines

Stack a movement snack onto something you already do every day.

Why it works

The hardest part of moving more is remembering and starting, not the effort itself. Anchoring a movement snack to an established habit borrows that habit’s reliable cue, so the movement triggers automatically instead of depending on motivation — the same cue-based mechanism that builds any durable habit.

How to do it

1. Pick a daily anchor: the kettle boiling, a bathroom break, the end of a call.
2. Attach a fixed movement snack to it ("while the kettle boils, I do squats").
3. Keep the snack small enough that the anchor reliably pulls it.

Evidence

Habit formation through context-cue repetition is well supported, and anchoring (habit stacking) is a practical application that supplies a ready-made cue for the new behavior. (observational)

The cue-repetition mechanism is studied; the specific "stacking" framing is practitioner advice built on top of it.

Common mistake

Relying on willpower or a vague intention to "move more" instead of attaching the snack to a concrete, reliable cue — so it never fires.
