Dr Heather McGee studies the part of training nobody can do for you: the behaviour. Her research on habit formation reframes the amateur's real problem — it's rarely a lack of the right plan, it's the failure to repeat it. The three habits of effective cyclists she's discussed on the podcast are less about physiology than about building systems that survive a busy life: consistency over intensity, identity over motivation, and structuring the environment so the right choice is the easy one. It's the psychology that turns a good plan into actual fitness.
