Gisele Bündchen and her jiu-jitsu instructor are reunited in familiar territory -- her home in Costa Rica, and she's giving him a peek at what her ex, Tom Brady, might be missing.
Gisele showed off her perfectly toned abs Monday as she got in some exercise with Joaquim Valente ... venturing out on a walk with a couple of super cute pups. We know GB retired from modeling years ago, but those abs still scream supermodel.
Costa Rica's fast becoming a favorite destination for Gisele and Joaquim .
