Online exercise programming may promote physical activity while at home, but little is known about its use among older adults. Using the Arksey and O’Malley framework, we describe the nature and extent of the research pertaining to the use of online exercise programming among adults 65 years of age and older. We ran two separate searches (January 2005–September 2020 and October 2020–October 2021), yielding 17 articles that met our inclusion criteria. A total of 1,767 participants (69% female) ranging from 65 to 94 years of age were included. Most studies delivered the online programs asynchronously. The majority of studies assessed the feasibility of online programs, with 14 studies investigating health-related outcomes such as physical, psychological, and social health. Future research should explore perceptions and experiences of online exercise programming among older adults and the mechanisms by which it impacts physical, psychological, social, and behavioral outcomes.
