Muscle worship is a form of body worship in which a participant, the worshiper, touches the muscles of another participant, the dominator, in sexually arousing ways, which can include rubbing, massaging, kissing, and even licking.

The dominator is almost always either a bodybuilder, a fitness competitor, or an individual with a large body size and a high degree of visible muscle tone, while worshipers are often, but not always, skinnier, smaller, and more out of shape. Muscle worship can include participants of both sexes and all sexual orientations.

The amount of forceful domination and pain used in muscle worship varies widely, depending on the desires of the participants. Sometimes, the dominator uses his or her size and strength to pin a smaller worshiper, forcing the worshiper to praise his or her muscles, while in other cases, the worshiper simply feels and compliments the muscles of a flexing dominator.

Both male and female bodybuilders often offer muscle worship sessions for a price in order to supplement their low or nonexistent income from bodybuilding competitions. Although these sessions rarely involve sexual activities, they offer fans--both male and female--the rare chance to meet and touch a muscular man or woman in person. [
