Exercise snacks directly address both: They\u2019re short, flexible, and easy to fit into daily routines.\u201d<\/p>\n<\/blockquote>\n<p>The study, published in the <a href=\"https:\/\/bjsm.bmj.com\/content\/early\/2025\/09\/26\/bjsports-2025-110027\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">British Journal of Sports Medicine<\/a>, suggests that exercise snacks could be an easy way to get some exercise every day, particularly if you are otherwise physically inactive.<\/p>\n<p><a href=\"https:\/\/www.memorialcare.org\/providers\/cheng-han-chen\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Cheng-Han Chen<\/a>, MD, a board-certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center in Laguna Hills, CA, who was not involved in the research, explained that \u201cthis review analyzed multiple previous studies and found that brief (less than 5 minutes) periods of moderate-to-intense exercise at least twice a day was associated with improved cardiorespiratory fitness.\u201c<\/p>\n<p>\u201cThese findings provide a potential avenue for sedentary people to obtain a health benefit with only short amounts of physical activity,\u201d said Chen.<\/p>\n<p>The researchers analyzed data from 11 studies, from Canada, Australia, China and the United Kingdom. The 414 participants (approximately one-third men and two-thirds women), ranged in age from 18-75 years.<\/p>\n<p>All participants were sedentary or physically inactive at the start of the programs and, in studies that recorded <a href=\"https:\/\/www.nhlbi.nih.gov\/calculate-your-bmi\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">body mass index (BMI)<\/a> \u2014 nine out of 11 \u2014 all participants were in the normal, overweight or obese category.<\/p>\n<p>Exercise protocols varied between studies. Participants exercised on 3, 4, 5 or 7 days a week, carrying out between 2 and 10 \u2018exercise snacks\u2019 per day at moderate to vigorous levels, for a maximum of 5 minutes at a time, over a period of between 4 and 12 weeks.<\/p>\n<p><strong>Types of exercise included stair climbing, leg-focused strength exercises and <a href=\"https:\/\/www.nccih.nih.gov\/health\/tai-chi-what-you-need-to-know\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">tai chi<\/a> \u2014 a low-impact ancient Chinese martial art designed to improve balance, strength and flexibility.<\/strong><\/p>\n<p>The researchers noted that 83% of participants stuck to the program for the entirety of the study they were involved in, which is much higher than for other exercise protocols, such as <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC10664287\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">high-intensity interval training<\/a> (HIIT), to which only 63% of participants adhere.<\/p>\n<p>The researchers assessed several outcomes, including cardiorespiratory fitness, muscle strength and endurance, blood lipids (cholesterols and triglycerides), BMI, body fat percentage and fat distribution. They also looked at balance, blood pressure, and mental health outcomes including anxiety and depression.<\/p>\n<p><strong>Even when participants were undertaking less than the CDC\u2019s recommended amount of exercise per week, exercise snacks resulted in statistically significant improvements in cardiorespiratory fitness (heart and lung function) in younger physically inactive adults, and in muscular endurance in older adults.<\/strong><\/p>\n<p>\u201cWhat\u2019s remarkable is that these gains were achieved with exercise volumes far below current <a href=\"https:\/\/www.who.int\/publications\/i\/item\/9789240015128\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">WHO [World Health Organization] recommendations<\/a>. This suggests that small, consistent bouts of movement can meaningfully improve fitness, even in people who find it hard to dedicate long periods to exercise,\u201d Rodr\u00edguez told MNT.<\/p>\n<p>However, the researchers emphasize that as only one of the studies compared exercise snacks with moderate intensity continuous exercise, they cannot determine whether these benefits are equivalent to those achieved with longer sessions.<\/p>\n<p>\u201cThe main message is that exercise does not need to be long, structured, or complicated to be effective. Short, repeated bouts of activity (i.e., \u2018exercise snacks\u2019) can significantly improve fitness with very little time commitment,\u201d Rodr\u00edguez advised.<\/p>\n<p>\u201cIt is important to recognize that exercise should ideally be individualized to maximize its benefits,\u201d he continued. \u201cThe response to training can differ substantially between adults and older adults, due to variations in physiological capacity, recovery rate, and baseline fitness. To optimize health-related outcomes, some degree of programming and personalization of these exercise bouts becomes necessary.\u201d<\/p>\n<p><strong>\u201cNevertheless,\u201d he added, \u201cany opportunity throughout the day to move, even briefly, can make a meaningful contribution. Incorporating short, vigorous snacks of activity whenever possible remains a highly valuable and accessible strategy for improving overall health and cardiorespiratory fitness.\u201d<\/strong><\/p>\n<p>Chen agreed: \u201cThis form of exercise might be an efficient way for busy and\/or sedentary individuals to get at least some cardiopulmonary benefit with only brief periods of higher-intensity physical activity.\u201d<\/p>\n<p>For those who are physically inactive and\/or short of time, Rodr\u00edguez suggested a number of different activities that can be easily fitted into daily routines:<\/p>\n<blockquote class=\"is-layout-flow wp-block-quote-is-layout-flow css-34gtoi\">\n<p>\u201cFor healthy adults, practical examples include fast stair climbing, bodyweight squats, lunges, push-ups, or even burpees, provided that their physical condition allows these higher-intensity movements. For older adults or individuals with lower fitness levels, more accessible activities such as chair stands, light resistance training, or short bouts of balance and coordination exercises like tai chi can be highly effective.\u201d<\/p>\n<\/blockquote>\n<p>However, he added that, particularly for those over 50 years of age, \u201cbalancing intensity, safety, and consistency is essential when implementing exercise snacks in everyday life.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Share on PinterestTo boost heart and lung health, swap the couch for \u2018exercise snacks\u2019, researchers advise.
