A New Jersey native, Stensland was a Division I swimmer before transitioning to the professional triathlete and endurance sport circuit. Now she practices parkour and all of the supporting work that allows her to be a true fit athlete: warm-ups, cool-downs, recovery and strength and power development in the weight-room.
