damn straight. the biggest difference isn't even actually the puff of the fat, but rather that the muscles compensate for the weight against the ropes. it's like trying to lift a person while dancing who wants to be lifted, and lifting a sleeping person. the sleeping person is just dead weight, the dancing partner is using their muscles to lessen the strain on yours. same goes for ropes, your body will just naturally compete to balance itself while your in the air, it just might take a bigger length of rope to give them enough support.
