Steroids can be anabolic and catabolic. If you take them you get bicep or biceps, sometimes you get tricep and triceps also. I nice pec is often seen in bodybuilding. If you are into body building, you turn into a bodybuilder. If there are more bodybuilders weightlifting rather than training, it is no longer called bodybuilding but weight lifting instead.
Weightlifters are into power lifting.
I am into sexy fitness babes and hardbodies.
