The ideal cycle you want is focus, rest, focus. It's an energy trap if you get tired from focusing but your rest activity doesn't refresh you back into focus mode.

In my experience, it's not that you replace energy traps with energy recovery - you instead create plans that allow for more focus, rest, focus cycles throughout the day.

If your work drains you completely when you go home, maybe you can try to create some plans for how to approach work holistically, sparing some energy for life outside of work.

For instance, create a plan that ends the work day with a lot of energy to spare by adding in a lot more rest cycles, including naps (laying down with eyes closed also restores energy) and walks. I also find creative outlets like writing or music quite restful, and as others have mentioned, a surprisingly lot of things restore energy - you just have to discover and note them down.

Not the OP, but for me energy restoring activities are “active” ones, like hobbies where you create/build something. Working on a painting, photo, sculpting, writing, working on a side project, playing intelligent games with your dog, ... Passive activities, like consuming TV or Netflix or worse social networks, at least for me are draining my energy levels.

By they definition, isn't going to work an energy restoring activity?

A hobby is something you go out of your way to do because of personal passion. If you approach your job like it's a vacation, then probably.
