Cafeteria-style platforms like Pluxee, Benefit Plus, or Edenred work on a points or credit system, where employees choose for themselves how to spend their allowance across a wide menu of benefits – sport, culture, health, and more. InBody measurement can sit inside that menu as one of the optional items employees can spend credit on.
MultiSport solves a different need – regular access to gyms and sports facilities, i.e., the activity itself. InBody, by contrast, doesn't address where or how someone trains, but gives feedback on whether that training and diet are actually showing up in body composition. The two tend to complement each other rather than compete.
For HR, it's practical to treat InBody as an addition to a broader benefits mix, not a replacement for it – whether it's a standalone item inside a cafeteria platform or a company health day run outside one. When communicating it to staff, it helps to emphasize the concreteness of the results and the privacy of the data; when planning frequency, it helps to build around the annual budget cycle and what you learn from the first round.
