Going to the gym even when I don't have energy to do the workout. I don't mean forcing myself to do it anyway, I mean just going there - sometimes doing lighter workout, sometimes doing just light cardio (eg. walking while listening to podcasts), sometimes just going to the sauna, and sometimes just coming to the gym to walk right back. However, most times, I'm more languorous than tired and after a warm-up I do the whole workout. And strength training is great for a) general health b) better mental performance c) looking good d) having more energy.
