For the starring role in the Iron Man series of films, Robert Downey Jr. had to pack on 20 pounds of pure muscle in order to become Tony Stark in a tin can.

In addition to a mega calorie diet of healthy food and protein shakes, RDJ punished his body with mostly body weight, kettlebell and sandbag exercises to create a physique that make him look like “he had the power to forge iron”.

It’s a good thing that Downey Jr got strong for this role…the Iron Man costume weighed 90 pounds.

  1. didn’t expect to see Michael Chiklis’ name on this list…but seriously…

    I have the utmost respect for all these actors and others that are able to transform themsleves like this, but one thing I often say to friends and family members who I disuss fitness/fat loss with: these actors are being paid-usually milliions of dollars-to make these transformations…also, I have ZERO doubt that at least half of them are using some combination of steroids/GH/???

  2. I really respect how deep some of them get into character. My question is from a health standpoint, are there any effects, maybe as they get to middle age, on their overall health specially for those who transform so drastically.
