Why is grocery shopping not listed as excercise?

Today I grocery shopped, loaded the car, unloaded the car and put the groceries away. I shopped for the week so I had a lot of groceries and heavy items. It took 2.5 hours of physical activity! I think this should be trackable! It’s a work out! Besides that I was proud of my cart! A good 1/4 of it was fruits and veggies, then healthy meats, whole grain bread, canned beans for chili, eggs. The chips I got were baked and I got some quick protein bars that I can grab for lunch or a snack. I prepped most of the fruit except still gotta do a watermelon and pineapple. I’m proud of my 1st solid week in awhile. I’ve planned my dinners for the week and have lots of good choices for the other meals. Today I had grapes while I cooked dinner and that kept me from pre dinner snacking. I’m finding if good options are available and easy, I’ll make better choices.
