This will depend on how you commute. I agree that exercise is important but if I were commuting within the city that I live, I would be driving to work and walking maybe 10 steps to my car and 20 steps to my desk. In a large urban centre where you are dependent on public transit then this might be a benefit. Edit: I will also point out that, in my opinion, when I'm choosing my own "WFH" arrangements, the onus is on me to make whatever choices suit my health and lifestyle. The employer has no obligation or responsibility to actively promote and encourage any lifestyle choices in my opinion (I actually get really annoyed when employers try to do this - just let me do my job and stay out of my personal life). But they sure as hell have a responsibility to reduce risk and hazards while on the job to every reasonable extent.
