Just had a little scare the other night when I went to use my flat bench. Sat down on the edge and lifted my dumbells to begin and felt the bench move back to front in a rather wobbly motion! 
Turned it over and checked all the bolts - 4 of 10 were coming loose
Here endeth Psymonkee's safety reminder!
