Work vs. workout

As life becomes busier I am finding these two elements, work and workouts, are becoming more adversarial to each other.  I still have the choice to get up at 5:00 and do the workout.  That is true.  However as the work days become longer with after school obligations, the energy level needed to perform well has become more of a struggle.  This morning I am about to set up, with my students' help, 1,650 chairs and label them for the ALF Parade.  Then I will walk two miles and stand for another two hours.  After that, I hope I can have the motivation to do legs and back.  If it was anything but legs it would be no problem.  We'll see how it goes.
