Definitely. Both Robby and Boyer Coe beefed up in weight for the Masters in the 90's (Robby more successfully). Robby was up to 235 pounds in the mid-90's (around 30 pounds more than what he used to compete at). Robby still looks great today for a man in his early 70's.
I thought the extra weight looked better on Boyer -- Robby seemed smooth in that first Master's show -- but a few years later, when Robby was working with Trevor Smith, he was bigger and as cut as ever onstage. The judges insulted him by placing him behind that dwarf guy, Flavio Baccinini or somesuch, when Robby actually could've taken a great but *very* complacent Vince Taylor.
