I'm looking for ideas for a weight lifting themed cake for my grandson. I put it in the search box and I'm getting Minnie Mouse cakes, Tigger, everything but weight lifting. What am I doing wrong?

Try putting in "weightlifting" to get a few more on cake central.  It all depends on how the cake picture is labeled.  However, you will find a much larger variety if you google weightlifting or bodybuilding instead.
