My point is that measuring energy use from exercise isn’t very meaningful since energy use by animals is so complicated. It seems wrong to say that exercising more increases your carbon footprint.
Maybe studies that meaure the effects long term energy in response to increased exercise. But either way, some amount of exercise is necessary for human health. Biking to work instead of running on a treadmill is clearly carbon negative. Or maybe people biking to work will cause them to get a wasteful biking hobby where they buy a new carbon fiber bike every year.
