Did you know butterfly sit-ups - a fantastic core workout - are inspired by Nature? Watch the Gorongosa Rangers move their bodies and open and close their arms like butterfly wings for the Tusk Wildlife Ranger Challenge.

Join us in celebrating the strength of the Rangers who protect our natural world. ----- Sabia que os abdominais em borboleta - um exercício físico fantástico - são inspirados pela Natureza?
