Tie new habits to existing ones (habit stacking)
Linking a new behaviour to an existing routine dramatically increases follow-through by using established neural pathways as an anchor.
- When a client wants to add a new habit but keeps forgetting
- When a client has tried and failed to start a habit from scratch
- When goal-setting — to anchor any new behaviour to an existing routine
- When reviewing a habit that has been inconsistent
Starting a new habit from scratch requires enormous willpower because it has no automatic cues. Habit stacking, a concept popularised by James Clear in Atomic Habits and grounded in earlier behavioural research, solves this by attaching the new behaviour to something the client already does reliably.
The formula is simple: "After I [existing habit], I will [new habit]." Because the existing habit is already automatic, it becomes a reliable trigger for the new one, requiring far less conscious effort to remember.
A client wants to add a daily mobility routine but keeps forgetting. Instead of "do it every morning", the coach suggests: "After you pour your morning coffee, do 5 minutes of hip stretches while it cools." Two weeks later, the client reports 100% consistency — something they'd never managed with the abstract intention.
Word-for-word phrases you can use in session.
- What's one thing you do every single day without fail?
- After you [existing habit], what if you [new habit]?
Let the client name the anchor habit — their own routine is more reliable than one you suggest.
Ask your next client to list three things they do every single day without fail (brush teeth, make coffee, open their phone). Together, choose one new habit and attach it to one of these anchors using the "after I... I will..." formula.
Include habit stacking as a default question in your initial client intake: "What existing routines could we build your new habits around?"
- Choosing the anchor habit for the client — if they didn't identify it as automatic, they won't rely on it.
- Stacking onto a habit that's itself inconsistent — the anchor needs to be genuinely automatic, not aspirational.
- Over-stacking — adding multiple new habits to a single anchor makes the whole chain fragile. One stack at a time.

Make the target behaviour ridiculously small to start
Shrinking a new behaviour to its smallest possible form lowers the motivation threshold, making the first repetition almost effortless.
Turn intentions into action with if-then planning
Specifying exactly when, where, and how a behaviour will happen — not just that it will — more than doubles the likelihood of follow-through.
Design the environment to make the right behaviour the easy one
Changing the physical and social context — removing friction from good behaviours and adding it to bad ones — is more reliable than relying on willpower or motivation.
