Definitely start the day with stretching then get on the treadmill and walk for about 20+ minutes.   Do this 3 or 4 times per day leading up to your 1st workday.  It's still going to take a few weeks for your body to adapt to being on your feet and using different muscles but you'll get into the groove within a matter of time.  Also, take an aleve before bed to relax your bones to feel good for the next day.

 

Good luck --- just remember ... you gotta start somewhere and the more you move around, ultimately the more energy you'll have.   Burning energy actually generates more energy as well !!
