Real Weight Training

Have you ever tried to lift large boxes made out of mdf?  No?  Well, then you can't HANDLE the real weight training!
 A few years ago my husband and brother-in-law built these in our basement.  It took 897 coats of semi-gloss white paint to make them look like this.  They still aren't done because I still want some sort of crown molding at the top. 
Now my husband is working on the bookshelves to match for the other wall.  These are some HEAVY boxes.  Especially after six days of working out and a 75 minute workout this morning.  That being said, won't they look marvelous?  We have only been working on them...for a year.  Ya know - some things get done slowly around here.  My goal is to have them done by summer 2014.
