A far cry from Margot Robbie's lax diet plan for her role as Jane in The Legend of Tarzan, the blond bombshell's Suicide Squad fitness routine makes us exhausted just thinking about it.
Robbie met with trainer Andie Hecker three hours a day for the majority of the week during filming to sculpt her body into supervillain status. "She was a total trooper," Hecker tells People. "It was very satisfying to see her body change into exactly what she wanted it to look like in such a short time."
And while Robbie's character Harley Quinn may take no prisoners as a violent assassin, the actress's fitness routine while gearing up for the role was a bit more glamorous: ballet jumps, Pilates, and jump rope were on the daily docket as forms of "non-bulking cardio."
Since Harley's outfit called for a pair of teeny-tiny shorts that leave little to the imagination, backside-toning moves were especially important. "We did a lot of heavy-weighted, low reps of arabesque pulls hooked up to resistance pulleys, as well as arabesque lifts with heavy ankle weights, in order to build and lift the butt," Hecker explains. "We also did a ton of side series outer thigh work, targeting outer glutes with high reps and low weights, to pull those muscles in and create a beautiful line from the waist to the upper thigh."
