Back in New York City

I hardly know where to begin.  Just spent five days in AMI.  I exercised a fair amount.  First day there (Friday) I did 4 x 400m (more or less) runs with 20 sqauts and 20 side-to-sides after each.  One other day I ran 3.3 miles in 30 minutes, and another day I did 3 x (200m, 400m, 600m) except I didn't finish that one.  Finally, yesterday I did 4 x 4 minutes on, 2 minutes off.  Not enough strength, obviously!  And not enough stretching.
