The clothing worn during an athletic endeavor must be functional on many levels: Appearance, performance enhancing or supporting, protective, comfortable to wear, stylish and appropriate. Every sport has clothing specific to their field and bodybuilding is no different. NOTE: Anyone who thinks that bodybuilding isn’t a sport, come down to the gym for a workout with an enthusiastic, professional bodybuilder. No athlete spends more time at training than a bodybuilder. Bodybuilding might even be considered an “extreme sport.”
