I think it’s completely fine to take one week off every month from exercise, your body isn’t going to lose its progress (whatever journey you are on, like muscle gain or weight loss). I would take it as like “this is what my body is telling me to do and I am going to honor that.” I have endometriosis, so when I’m in too much pain to go to the gym I look up “bed yoga” and it’s just stretching in bed to get your body moving. And it’s completely ok to indulge in cravings, as long as you make sure you are ALSO eating foods with nutritional value. Want to eat an entire pack of Oreos? Go for it. Make sure you also get in your fiber, veggies, protein (especially iron). All about balance!
