You don't have to keep competing to make a great living. Look at all the retired pros who are still making a living off bodybuilding. Dexter is a promoter now, so maybe he will go down that road.
yeah i'm betting he's onstage another 2-3 years.
promoters break even or lose $ a lot of the time. Dex can make 75 to 100k doing smaller shows, plus endorsements, guest posings, etc. Unless your name is Ronnie, you lose a lot of that $ when you retire.
