Exercise snacking, a concept introduced in 2007 by Harvard cardiologist Howard Hartley, refers to short bursts of physical activity lasting from 30 seconds to around 10 minutes. Activities can include climbing stairs, walking, squatting, or even dancing. Research now supports the effectiveness of these mini workouts in enhancing health and fitness.
A 2022 study showed that performing brief exercises such as stair climbing or cycling for just 15 to 30 seconds, three times a day, significantly improved cardiorespiratory fitness among inactive adults. More strikingly, a 2023 study involving over 22,000 participants found that those who incorporated just 3.4 to 3.6 minutes of vigorous activity daily saw a reduction in cancer incidence by 17 to 18 per cent. Increasing this activity to 4.5 minutes led to a 31 to 32 per cent decline in cancer rates. Additionally, even small amounts of moderate to vigorous exercise daily can lower dementia risks, demonstrating that every little bit helps.
Fitness experts like Michael Betts stress the importance of movement, advocating that any activity is better than none. Betts highlights how “exercise snacks” can be simply integrated into daily routines, illustrating that they need not require lengthy commitment. For example, walking is an easily accessible starting point; it can commence with leisurely neighbourhood strolls and progress to interval training, where intensity varies.
Furthermore, Supatra Tovar, a health psychology practitioner, believes in initiating small, manageable behavioural changes that can effectively lead to long-term habits. She recommends linking new movements to existing daily activities—like a few jumping jacks following tooth brushing—making it more likely to become routine.
There are countless ways to incorporate exercise snacks into everyday life. For instance, mundane tasks like cleaning or playing with children are forms of non-exercise activity thermogenesis (NEAT), expending energy while performing regular duties. Even simple modifications can elevate the effectiveness of workouts, such as upgrading wall push-ups to floor push-ups or walking turning into jogging.
Ultimately, adopting these brief ‘exercise snacks’ can lead to substantial health improvements over time. The collective evidence suggests that these small shifts toward more active lifestyles can yield considerable benefits. By maintaining consistent, minute exercises throughout daily life, individuals reinforce their body’s need for movement, encouraging long-term health and vitality.
