Exercise snacks are an emerging form of physical activity characterized by shorter single bouts of high\u2010intensity exercise spread out repeatedly throughout the day which can provide more exercise opportunities for middle\u2010aged and older adults.<\/jats:p><\/jats:sec><jats:sec><jats:title>Purpose<\/jats:title><jats:p>To summarize perceptions and experiences of exercise snacks among middle\u2010aged and older adults, and explore the barriers and facilitators of promoting exercise snacks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We followed the PRISMA and systematically searched five databases from the earliest to May 2024.
