Gisele Bündchen had some company during her workout Wednesday morning – none other than fellow Brazilian mama Camila Alves.
The ladies arrived separately at their Studio City, Calif., gym, the Tracy Anderson Method Studio, early in the morning – but they were happily chatting (and sweating) together during their long, strenuous workout.
“Yoga stretches are very important to Gisele,” a source tells PEOPLE. “She showed Camila a few stretching and abs exercises that are great for new mothers.” Trainer Tracy Anderson, whose workouts include Pilates, wasn’t present.
According to the source, “Gisele and Camila seemed to enjoy working out together – and had fun chatting during the workout.” – Pernilla Cedenheim and Ainka Shackleford
