Activity Level

I had a question about setting my activity level. The in app setting are mostly geared towards your job and make no mention to the amount of exercise you normally do. Is this because you already get credit for these when you enter your cardio for the day? The reason i'm asking is because i'm in the Army, but I mostly work in an office. I workout 6-7 days a week, but based off my daily job i'm lightly active. Is this right?
