Open workouts for UFC 212 were held Wednesday in Rio de Janeiro. Headliners Jose Aldo and Max Holloway showed out for the fans before their featherweight championship unification main event on Saturday. Co-headlining strawweights Claudia Gadelha and Karolina Kowalkiewicz, as well as the legend Vitor Belfort were also featured. One question though, why does Vitor take a service dog everywhere with him now?
