They will both make pretty decent money between guest posing, contracts, potential contest winnings and the such.
Both will feel the need to "prove" to everyone that they're not the poor bodybuilder everyone claims as truth on the internet. Therefore, rather than invest much of that money into retirement funds, bonds, mutual funds, or other investments which would allot them a financially secure future, they will buy expensive cars brag about the price of their watch and other things of that nature. When they are forced to retire from bodybuilding for whatever reason they will be dirt poor.
See Flex Wheeler for the full manifestation of this process.
