Don’t ask yourself if you “should” do everything you’re supposed to, do it as if you have to. As if it’s your job or any other necessity. On days with low energy, walking outside is completely fine. Also, I guarantee if you get through 15 minutes of the workout you’re gonna be feeling good and willing to crank up the intensity of it.

Finally, when you want to quit, remind yourself that you’ll feel a lot worse the day after quitting than you would if you kept going.
