They go on an "adventure" and learn about different things while exercising. Yesterday they went to Yellowstone to investigate the super volcano that lies under it. They walked, ran from a bear, climbed a tree, climbed a mountain, hopped rocks, etc. All I heard about today was how they couldn't wait to do it again!
It's for the younger age for sure. Mine are 3 and 6. If you sign up as a teacher it's free :)
