Competition Weight Classifications

I always wondered what the weight classes were exactly. When I found these, I thought it would be informative to post them here. The weight classes listed below are in compliance with the IFBB.

NOTE: A few organizational bodybuilding competitions omit some of the Senior Men's categories listed.
