For decades, health advice has been about getting a set amount of exercise each week, whether that’s 150 minutes of brisk walking or 75 minutes of vigorous activity. While well-intended, these guidelines can feel unreachable for people juggling work, family and daily obligations.
In recent years, a fresh concept has been gathering momentum in health science, it is called the Vigorous Intermittent Lifestyle Physical Activity, or VILPA, also known as gym snacking. Unlike traditional exercise routines that demand dedicated time, special gear or gym memberships, gym snacking or VILPA is all about inserting short, intense bursts of physical activity into the rhythm of daily living, and evidence suggests even tiny doses can ripple into remarkable health dividends.
According to Jo Blodgett, senior research fellow at the Institute of Sport, Exercise and Health for University College London, this shifting paradigm could be a game-changer in how we view physical activity and public health.
Speaking to the BBC Radio Four podcast, she explained that VILPA, essentially short blasts of high-intensity movement woven into everyday living, can deliver measurable gains for heart health, longevity and resilience without demanding hours in the gym.

One of the easiest ways to spark VILPA is by embracing activities already in your path. Climbing two flights of stairs briskly, turning a walk into a power march between lampposts or speed-walking to catch a bus can all raise your heart rate just enough to matter. These moments may last less than two minutes, but over a day they accumulate into potent heart-strengthening doses.
Don’t underestimate household chores. If you pace with intent while cleaning, carry shopping bags with brisk effort, or play energetically with children, you’re unconsciously embedding vigorous movement into your life. Blodgett stresses that finding joy and purpose in these micro workouts makes them far more sustainable than forced gym sessions.
Stop wondering how long to workout, instead focus on how to include intense movement, even briefly. Setting simple cues like “power walk for one minute between calls” or “climb stairs promptly when you can” helps shift the narrative from chore to chance. It’s progress over perfection, and that makes all the difference.
Blodgett points out that many of us fall into the “active couch potato” trap, we may do a weekly class but then sit for hours. Interrupting sedentary time with short, vigorous movements every 30–60 minutes enhances circulation, energises metabolism and chips away at health risks linked to prolonged sitting.

Perhaps the most profound shift comes in how we feel about physical activity. From tapping your feet while cooking, or racing for a train. These aren’t “fake workouts”; they are proof that movement needn’t be intimidating or regimented to be effective.
