66. Who’s Talking in There? The Science (and Practice) of Your Inner Voice
Ever catch yourself mid-lift arguing with… yourself?
In this episode, Jess digs into the surprisingly powerful science of self-talk — why that inner voice exists, how it shapes your confidence and body image, and three evidence-backed ways to train it so it helps instead of hijacks you.
You’ll learn:
- What self-regulation actually means (and why it matters under the bar and in daily life)
- Why talking to yourself in the second person (“You’ve got this”) changes your stress response
- How to use self-compassion without slipping into toxic positivity
- How your inner dialogue directly affects body image and self-trust
- Three sturdy tools you can practice this week to start shifting your tone
