Stairmaster

6:30 a.m. it begins:

Down 6 flights of stairs to walk the dog for 30 minutes or 8 blocks, whichever comes first,
Back up to get ready for school.
Back down 6 flights, walk 3 blocks to the S-Bahn station;
Up 2 flights and down 2 flights to get to the platform.

8:00 a.m., arrive at Alexanderplatz, down 2 flights to street level,
6-block walk to school with my crepe-to-go breakfast.
Arrive at school,
Up 2 flights to class.
10:00 down a flight to the break room, back up 30 minutes later.
Down and up again for the noon break, then
Down 2 flights when class is over.

Wander Mitte for an hour to stretch my legs after so much sitting,
6 blocks back to Alexplatz and
Up 2 flights to the S-Bahn to return to Ostkreuz station.
Up 2 flights and down 2 flights to get back to the street.
Walk home - 3 blocks.
Up 6 flights to collapse on the couch.

4:00 p.m., after a rest,
Back down 6 flights to walk the dog for an hour or so,
Back up, a little more slowly. Hmmm. Maybe a lot more slowly.
Down again - to the grocery store, or an apartment viewing (more train stations, more stairs),
or out for dinner, then
Back up again, perhaps laden with bags. (Or a piece of furniture from the flea market. But that was on Sunday.)
10:30 p.m., down 6 with the dog, one last time;
Up the final 6, and
then to bed.

No wonder the Germans have such sturdy thighs.
