reacweb may not be a native English speaker (they live in France). I'd assume "sport" translates to "exercise". Like running or biking.
Sport has plenty of (somewhat archaic) meanings. "Sporting goods" stores often carry running shoes, bicycles, and weights, all of which are "sport" even if you're doing it by yourself.
