A tattoo will only add a minor, miniscule, insignificant, unnoticeable, irrelevant, inconsequential, negligible gram or two to your body weight. The weight of the ink in an average tattoo is estimated to represent 0.0004% of the average person's weight. No matter what your morphotype, muscle mass or fat ratio, and no matter what activities you may or may not pursue now or in the future, a tattoo can have no impact in any way on anything having to do with your figure, looks or physical capacities. For proof, just look at the people who rely most on their bodies: there is hardly a single actor, fashion model or sports figure today who doesn't have at least one tattoo.
