Nobody can answer this for you. They are describing what works best for them. Find what works best for you. Forget what is optimal. What is something you can do consistently for years. If that's walking, then walking is still better than sitting. I found watching TV while working out is a great motivator. Consider that as well. And lastly. I've been working out consistently for over a decade. I still don't like it. Get your feelings out of this. Think of it like brushing your teeth.
