Swimming Instruction for Individuals with Higher Body Density

Question
In - reference to swimming literature, describe how you would use this information in teaching an individual with a highly dense body mass?

Answer
A persons body mass has very little to do with learning how to swim.  I would teach them the exact same way I would teach someone with a less dense mass.  If a person is muscular(more dense) it may be harder to teach them to float, but beyond that it is the same.
