Phil Heath 5x Mr Olympia is looking bigger than ever. In his recent guest posing it is obvious that Phil has gained A LOT of quality muscle to his physique. I cannot think of anyone except Kai Greene who can rival this physique.
There is uncertainty if Kai will compete at the Olympia and by the looks of it he is not competing.
Phil however is well on his way to win the 6th Olympia title.
