I exercise every day, unless I'm ill or injured or just feel really tired. So maybe about once every 6 months or so, I might take a day off.

However, my exercise intensity and duration vary.

One day I might do a long, hard bicycle ride ... the next day I might do a short walk.

If I've put in some effort, I'll often want a hot shower, glass of water, and a dinner with a few more calories. Otherwise it is just business as usual.
