Implementation intentions

If-then planning.

The technique

Specify when, where and how in advance: if it is Tuesday at 18:00, then I walk for twenty minutes. This has among the better evidence bases in behaviour change.

  • It works because the decision is made once, in advance.
  • Include a fallback: if the gym is closed, then I walk instead.

Why it helps

Most failures are not lack of desire but the moment of deciding while tired. Pre-deciding removes that moment entirely.
