Do it on bad days, as long as nothing else prevents you from doing it.
I'm having a bad day today. Tired and zero energy. I'll spare you the reasons. I worked from home again today, and when it was time to exercise, I just didn't want to do it. My mind and body were screaming no. Somehow, I just managed to drag myself to my home gym and got it done anyway. I am still tired, and the exercise didn't lift my energy, but I am still satisfied I got it done. It wasn't even a bad workout, so I know my routine is working. I'm sharing this in the hope that you will feel inspired and think about this story when you're tempted to skip a workout. You aren't alone with that feeling, and it is entirely possible to push through and get the work done, even on the bad days. In conclusion: Train on the bad days, if you aren't injured. Just get it done! 👍
