The Liv dolls are given plenty of outdoor activities or reference to activities e.g. The Healthy Teen Challenge.
Katie has a skateboard, a kayak, a windsurfer & paddle board and also a puppy that is taken on walks. The other girl dolls (except for Hayden) also have named puppies.
Alexis has a cabana for sitting on the beach or at the lake.
The three horses also encourage outdoor activities - with Katie and Hayden having named horses and a third horse named Nutmeg belonging to an unnamed doll (possibly Sophie).
