Social isolation and loneliness are critical health epidemics among older adults. The present manuscript aimed to underscore group-based physical activity (GBPA) as an approach to prevent and/or reduce social isolation and loneliness among older adults and, therefore, avoid its negative health consequences. We compiled evidence from the literature to answer the following question: would GBPA be a better approach to prevent/reduce social isolation and loneliness among older adults compared to individual physical activity? There is evidence demonstrating that older adults participating in GBPA not only acquire the well-known physical benefits of physical activity but also experience improvements in social connectedness, due to the fact that individuals exercising with others. To this end, beyond providing physical health benefits, GBPA for older adults may have the potential to help prevent social isolation and loneliness by improving levels of social connectedness in this age group. Further research is much needed, as the literature seems to be scarce. This would help devise tailored exercise programs for those reporting to be isolated or feeling lonely.
