AmbieP -- Welcome! Glad you found your way here. What kind of exercise will you do?
Just a word of advice: do set a goal you think you can make. I average 40 min a day, but I know a couple of days I will get in 60 min (when I weight lift), which allows me to take a day off now and again... which we need sometimes (and the experts recommend!). If you think your goal is too much, just say 30 min 6 days a week! Or, don't listen to me at all -- I won't be offended, I promise!
