Jessica Biel’s Brutal Butt Workout That Built Her ‘Unattainable’ Peach Shape

Jessica Biel’s Brutal Butt Workout That Built Her ‘Unattainable’ Peach Shape
  • PublishedJuly 15, 2025

Oh great. Another celebrity fitness secret that makes the rest of us feel lazy. Jessica Biel has once again raised the bar for what counts as a “normal” gym session after revealing the behind-the-scenes routine that sculpted her famously peach-shaped butt. While on the press tour for her latest film, The Better Sister, Biel spilled the tea on the exact moves that left her glutes looking like they were carved from marble.

In a recent interview with People Magazine, Biel admitted she owes her glute gains to a mix of weighted hip thrusts, Bulgarian split squats and high-rep glute bridge circuits. According to the actress, her trainer had her loading up barbells and resistance bands five days a week, capping each session with targeted “donkey kick” variations that isolate every muscle fiber. “It was brutal,” Biel confessed. “I remember thinking it was unattainable, but it worked.”

New York Post entertainment reporter Erin O’Connor corroborates those details in her exclusive scoop, noting that Biel logged weekly Pilates reformer classes and HIIT cardio intervals to balance the heavy lifting. Insiders tell Entertainment Tonight that Biel’s regimen wasn’t just about aesthetics; she followed a carefully periodized plan that increased weights every two weeks while rotating exercises to prevent plateaus. That meant swapping standard squats for curtsy lunges one session, then tackling box jumps and glute-ham raises the next.

The result? A peach-shaped posterior that fitness influencers are dying to decode. Biel’s approach leans hard into progressive overload, ensuring each workout pushes her limits. She even admitted to keeping a spreadsheet of weights, reps and soreness levels just to track improvements. If your fitness journal looks more like a doodle pad, you might want to rethink your game plan.

Despite the enviable end result, Biel stresses that her routine is not a one-size-fits-all solution. In an Instagram Live Q&A, she warned fans that genetics, diet and recovery play equally crucial roles. “You cannot just copy the workout and expect to look like me,” she rolled her eyes. “This took months, consistency and a lot of protein shakes.”

Still, for those determined to chase the peach, Biel’s revelations offer a clear blueprint. Prepare to spend at least an hour in the weight room, embrace soreness as your new best friend and resist the temptation to slack off on form. Because if you think glute bridges are easy, Biel’s version will remind you of the seven circles of fitness hell.

And that, dear reader, is why we cannot have nice things.
