Movement Snacks: Your Fitness Revolution in Seconds


Listen Later

In today’s episode, we’re flipping the script on what a “real” workout needs to look like.

You’ll learn how 2–5 minute bursts of movement — also called micro-workouts or movement snacks — can boost your metabolism, improve focus, regulate blood sugar, reduce stress, and build strength without needing a gym or workout clothes.

We’ll cover:

    • What movement snacks are (and how short is short enough)
    • The surprising research behind their health benefits
    • How to make them stick using the habit-stacking method
    • Real-life examples you can try today — even while brushing your teeth or waiting for the kettle to boil

Whether you’re a busy mum, desk-bound worker, or just someone who’s tired of “all or nothing” fitness plans, this episode will help you start where you are and build lasting change — 5 minutes at a time.

💡 Key Takeaways:

    • Micro-workouts can be as short as 20 seconds and still improve fitness, especially when done consistently throughout the day.
    • Research shows they can lower cancer risk (JAMA Oncology, 2023), improve cardiovascular health (The Journal of Physiology, 2019), and regulate blood sugar (ADA, 2014).
    • Movement snacks don’t need to be intense or sweaty to count — just frequent, functional, and consistent.
    • Habit stacking (from Atomic Habits) is a powerful tool to make movement automatic.
    • Movement is most effective when built into your lifestyle, not bolted on with pressure or perfectionism.
