Not everyone has a safe place they can go running
or ride a real bike or access to some place they can go swimming
, without joining a gym - I happen to be one of those. I'm all for a person doing whatever exercise they can, whether it be inside on the Wii and exercise bike, going to the gym or running outside, swimming, etc. The simple fact that peadot is moving is a step in the right direction.
The idea is to make healthy lifestyle changes that one can live with.
