Just short breaks, they usually go like this:
-feeling a bit tired, less focused
-get coffee
-sit down to enjoy it
-brain thinks of something to get done
-take coffee with me and get it done
Naps only if I'm physically trashed, sometimes in the weekend after training. But prefer to wait for the night to have a good nights sleep like others mentioned. If I rest too much during the day I have trouble getting to sleep or staying asleep at night. How is your routine?
