Agreed. I've always struggled with intense structured exercise. Instead I walk quickly, park at the far end of lots, run up the stairs instead of the elevator, do some jumping jacks while waiting for the microwave, and lots of small things like that and it seems to work. You can get a lot of exercise minutes and increased heart rate out of doing routine activities with gusto. Admittedly, it's not so good for building muscle, though.

While I see your point (0 > 1, by definition) I think this sends the wrong message.

You need several hours of relatively strenuous exercise per week. Walking around the neighborhood, or your house, or whatever has diminishing returns. You need to steadily increase load to continue to see results. The body is incredibly good at adapting. People will read your statement and walk around their house twice, sit down, and not move for the rest of the night.

Is this really a high bar these days?
