Counting Weekdays

I want to count the days backwards starting from today. But I want to the cells to fill in with the date (xx/xx/xxxx). Is there a formula that I can use that will start with today and then I can drag that down so it will have the previous day and so forth? I want my spreadsheet to look like this

example:
a1 = 06/08/2012
b1 = 06/07/2012
c1 = 06/06/2012

Keep in mind that I only want it to display workdays so dates for Monday through Friday. Any help would be great. Thanks.

Try

in b1: =WORKDAY(A1,-1)

and drag over
