Notice this happens with a lot of things people skip to "save time." @lucaschen's friend is a perfect example. Skipping the run to code more backfires because your brain is part of your body. If you let the body get sluggish, the mind follows. That morning movement isn't stealing your good hours, it's creating them. Your buddy's straight-into-code method would just leave me staring at a screen with foggy thoughts. Different engines need different warm-ups.
