During my attempt to shrink my database so that it would fit on my laptop (it was 20 gigs), I figured out that I needed to reindex all my tables.  Usually the format of your data and log files will follow this pattern – just replace the {DATABASE_NAME} with the name of your database.

DBCC SHRINKFILE ({DATABASE_NAME}_data,5)

DBCC SHRINKFILE ({DATABASE_NAME}_log, 1);
BACKUP LOG {DATABASE_NAME} WITH TRUNCATE_ONLY;
DBCC SHRINKFILE ({DATABASE_NAME}_log, 1);
