I've decided to track my total minutes exercising for each week. I'm setting 300 minutes as my minimum goal. I'll total them up on Sundays, because I rarely exercise on weekends. I'm going to count only deliberate exercise, not incidental exercise. When I get back from vacation, I would like to weigh myself at the doctor's and get an official weight; recalculate my BMI and BMR; start counting my BMR calories and subtracting exercise from that figure.
