Exercise snacks – intentional short bursts of physical activity – may be an effective way of boosting the cardiorespiratory fitness of physically inactive adults.
This is according to a review of the available research, published online Oct 7 (2025) in the British Journal of Sports Medicine.
Adherence to exercise snacking throughout the day was high, the findings indicate.
Therefore, this approach could help counter the perceived lack of time and low motivation – frequently-cited barriers to fulfilling the recommended weekly quota of physical activity for health – say the researchers.
Globally, around a third of adults and 80% of teens fail to meet the recommended physical activity levels of 300 minutes per week of moderate-intensity physical activity, or 75-150 minutes per week of vigorous-intensity physical activity, they note.
