I agree, but it all depends on how you define "get off the couch". Some people walk moderate amounts already and for those starting running makes a lot of sense

I agree, but it all depends on how you define "get off the couch". Some people walk moderate amounts already and for those starting running makes a lot of sense, while others move so little in their life that walking is the best first step. It is also perfectly fine if walking is the only step, but at least in my case I felt huge health benefits from going from walking moderate amounts to running (I still walk, but a bit less).
