His trainer Brad Bose told Us Magazine, “When we did ‘Iron Man 1,’ we had five months before the shoot to get ready, so we used more traditional, heavy-weight training.” Since Downey, Jr. had just wrapped ‘Sherlock Holmes,’ he was down to 151 pounds when shooting on ‘Iron Man 2’ began.
"After [the first routine], Robert felt kind of bored with it and wanted to do something a little more exciting, so we decided to do what I call a ‘Rocky IV’ meets high-tech training," says Bose, who bulked the 45-year-old actor up to 175 pounds over the first three to four weeks of filming.
More after the jump…
A few examples:
- Downey Jr. pushed "a custom-built wheelbarrow that we modified with 600 to 700 lb. weight stacks" around an obstacle course.
- "We went out and bought truck tires, and we used sledgehammers — anywhere from two 4-lb. sledgehammers in each hand all the way up to a 20-lb. sledgehammer — and we were just beating tires with it.
- “We used fire hoses that we filled with sand and water… and we’d drag and whip them to build the shoulder muscles and pecs back up."
- They also juggled "weighted Indian clubs," hulled around kettle bells and even used a war machine, which Boyes explains is "like a rope with handles on it with a pulley — you suspend yourself from it," says Bose.
The two would meet around 9:30 a.m. and work out for an hour-and-a-half at least three days a week. Downey Jr. also trained in Kung Fu two to three days a week with Eric Oram. Who says being an actor is easy?!
