Having been personal trainer for 16 years I’ve heard EVERY excuse in the book why clients didn’t have the time to exercise.  You have to decide what your priorities are, and then take action.  If you really want to lose weight, do something!  Even if you walk for 5 min., that’s 5 min. longer than you did the day before.  If each day you increase your walk by 5 min. within a week you’ll be walking for 35 minutes!
