Jessica Biel posted footage of her preparation for Matchbox The Movie, with long-time trainer Ben Bruno describing how he adapted her full-body workouts after a lower-back issue. A Fit&Well report breaks down the video’s advanced strength, balance and mobility exercises; it does not establish that the routine is suitable for everyone.
Jessica Biel has shared workout footage from her physical preparation for Matchbox The Movie, and her long-time trainer Ben Bruno says the routine was adapted after she tweaked her lower back. A Fit&Well report examines the video’s mix of demanding strength, core and balance exercises, while noting that the moves reflect Biel’s existing training level rather than a beginner workout.
Bruno says in commentary accompanying the video that viewers may focus on Biel’s back, but her training is full-body and places somewhat more emphasis on her legs and glutes than her upper body. He says she had tweaked her lower back a few months before preparing for the film, so he had to find ways to keep challenging her without aggravating it. The report does not provide a diagnosis or further details about the issue.
The footage includes wall-supported squats using a foam roller, performed with a goblet hold and with two dumbbells. Fit&Well’s trainer-author describes the wall and roller as providing support during the squat, while added weights increase the challenge. The video also shows ring rows, a wall-assisted Bulgarian split squat, band-resisted lunges, split-squat holds with a lateral raise, side planks and a side-lying press-and-reach.
According to the report’s exercise breakdown, these movements combine compound strength work, isometric holds and core stabilization. For example, the band-resisted lateral lunge makes the exerciser resist a sideways pull while reaching a weight toward the floor. In a split-squat hold, raising a dumbbell to the side adds an upper-body task while the legs and core work to maintain position. The report characterizes the overall selection as advanced.
What Biel’s Routine Shows
The video offers a specific example of how a trainer can modify a workout around a reported physical limitation while retaining challenging exercises. Bruno’s account centers on changing the exercise setup and demands, rather than treating the routine as a fixed list that anyone should copy. The foam-roller-supported squats are presented as one example of that approach, though the report does not establish that they are appropriate for every person with back discomfort.
For readers, the main takeaway is the difference between understanding an exercise and being ready to perform it. The moves require strength, balance and control, and some use external loads or resistance bands. The source does not report testing the workout on other people or provide a beginner version, so it should not be read as a universal training prescription.

From Back Workout to Film Prep
The Fit&Well report says Biel’s arm-and-back workout post drew considerable online attention in December 2025. Her newer footage shifts the focus to preparation for Matchbox The Movie, while Bruno’s comments push back on the idea that her program is primarily an upper-body routine. He describes it as full-body, with a greater emphasis on legs and glutes.
The report is an exercise interpretation of footage and trainer commentary, not a film production announcement or a clinical account of Biel’s back issue. Its descriptions explain the muscles and challenges involved in the visible movements, but the source does not give the full program’s schedule, sets, repetitions or progression.
“People understandably want to know about her back workout—the thing is, Jess does full-body workouts and actually focuses a bit more on legs and butt than upper body.”

Details the Video Cannot Confirm
The source does not state the precise date the Matchbox footage was posted, how long Biel followed this routine, or how often she performed each exercise. It also does not specify weights, sets, repetitions, rest periods or whether the movements shown make up a complete workout.
Bruno’s description of a lower-back tweak is the available account of that issue; there is no diagnosis, treatment information or update on her current condition. The exercise explanations are Fit&Well’s analysis of the footage, and the report does not establish that the routine prevents injury or is suitable for people with back pain. The circumstances of Biel’s preparation beyond the workout video are also not detailed.

More Film-Prep Details Await
No additional workout details or follow-up on Biel’s back were specified in the report. Readers can look to future posts from Biel or comments from Bruno for further information about how her training was structured, but no next update has been announced. Until then, the footage and its exercise breakdown offer a snapshot of the movements shown, not a full program or individualized guidance.
