One nice concept about workout is the deload week. Basically after 4 weeks of intense (sort of) workouts you take a rest week.
Why? The body adapts, grows, and the week after you’ll be better than ever.
We could apply it to any kind of topic and I think we could see similar results. Just like sprints in software, a deload week would allow the minds to refresh, to take a moment so they can be more productive right after that.
