This is an animated advertisement with the aim to inspire and encourage people to make more active choices about how to spend their time. Exercise is portrayed as invigorating and social, whereas TV watching is portrayed as a more solitary choice.
The protagonist is relaxing on the sofa when the split screen allows us to see what else she could be doing. All 3 versions of herself are seen together at the end. The refreshed swimmer and the sociable skaters sit alongside the sleepy sofa sitter. They disappear when she wakes, leaving her alone, reflecting she did not make any of those more active choices.
