The Iron Man 2 Workout
How Robert Downey Jr. trained for Iron Man 2 and beat workout boredom
In Iron Man, Robert Downey Jr. impressed audiences with a lean, mean,
fighting-machine physique. As Tony Stark, an engineering genius with a
penchant for women and adventure, the 5 feet 8 inch Downey weighed in at more
than 170 pounds, with sinewy arms and rock-hard muscles that came from months
of grueling workouts.
After that film, however, Downey switched gears. He dropped 20 pounds to
play Sherlock Holmes – a thin, reed-like character with smaller
So when Downey learned that he would once again be playing Stark in Iron
Man 2, the challenge was on.
From Sherlock to Iron Man 2
"We had to do some pretty drastic stuff to get him up near the 170-plus
pounds of Iron Man," says Brad Bose, PhD, the exercise physiologist and
kinesiologist who sculpted Downey for all three films.
And they had to do it quickly. Downey had only three months to prepare for
Iron Man 2 – and a full 20 pounds to regain.
On top of that, Bose says Downey was exhausted from the diet and training he
had done for Sherlock Holmes and was bored with traditional
"As mentally strong as he was, the body was tired," says Bose, who owns Bose
Management in Santa Monica, Calif.
"Robert said, ‘If I have to get underneath a bench press or [do] a squat,
I'm going to shoot myself. I just don't have the motivation.' So his
challenge to me was to make the workouts fun and challenging."
Bose hit the books, researching long-forgotten and exotic training
techniques. His goal: Chisel Downey's body into one that fit Iron Man's
character – not just get him back into shape.
"The role was a much different person than the typical Marvel superhero, who
tends to be an overbuilt, buff kind of guy – the guy who's big and muscular and
strapping, and who almost looks like a body builder," Bose says. "The character
of Iron Man was a playboy millionaire, a misunderstood scientist, a
techno-geek. It didn't fit him to be a big, overly muscular guy."
