Jessica Biel is in stealth mode—one resistance band at a time.
The Better Sister actor shared a look at her back and arms workout routine, months after showcasing her very toned upper muscles in the Prime Video series.
“The arm and back workout everyone asked for is finally here!” Jessica wrote on her Nov. 23 Instagram video, which featured a voice over from her trainer Ben Bruno. “Thank you to my friend and amazing trainer @benbrunotraining for all of the help leading up to The Better Sister but also for my everyday life.”
In the reel, the 43-year-old—who shares sons Silas, 10, and Phineas, 4, with husband Justin Timberlake—did several reps of her favorite moves, ranging from seated pull ups and single arm lunges to inverted rows that ended in a deep squat. Though this routine looks intense, Ben noted that she “doesn’t do all these moves in one workout.”
Instead, the 7th Heaven alum will choose a handful of different moves, depending on which area of her back and arms she wants to work on in that specific session.
“In any given workout, she’ll do an exercise for the back, which mostly works the biceps,” the trainer explained of her approach, “one exercise for shoulders, one exercise for triceps, plus some other moves for legs and abs sprinkled in.”
He also offered a word of advice to anyone looking to replicate this regimen.
“It’s also important to remember that it’s impossible to maintain peak physical condition all the time, and the super toned physique that you see on screen isn’t maintainable all year round,” he continued, “Jess knows that, so she spends most of the year working out consistently, but not crazy by any means.”
In fact, Jessica echoed that sentiment when fans first asked about her Better Sister workout routine in July.
“That peak shape in the show is not maintainable unless you are living the strictest, most rigid lifestyle with your nutrition and fitness, which I cannot do,” she said in her TikTok video at the time. “I’m currently back on my plan to get a little bit back towards that shape.”
She then showed off her hip thrusts to lower ab-lunge combo, noting the exercise has helped her “build muscle”—which shined in her multiple outfits from the show, including that sleeveless, high neck gown—over the years.
“My body is not 20 years old anymore, you know, so I’m adjusting my workout to what I need to do,” she continued. “You gotta build muscle. So that’s a key part of my particular program. And a ton of flexibility. Let’s get older and stronger together.”

Kaley Cuoco
Eight months after welcoming her daughter Matilda with Tom Pelphrey, Kaley noted why she loves doing treadmill workouts amid her postpartum fitness journey.
"Putting that incline up is so good for your muscles, and for your circulation," she told Today.com in an interview published Nov. 22. "I'll also walk backward, which is amazing for your butt and legs. It pretty much works everything."
Becky G
After having a transformative year in 2023, Becky revealed how fitness played a major role. "I know at the end of the day who benefits from a healthier me the most—myself," she told E! News. "Eventually, if you dedicate yourself to it, you will have lived your life longer with this habit than you ever did without it. At least, that's the way I like to think about it."
Her go-to workouts? "If it's a home work out, if it's stretch, if it's going outside for a walk—I try to be as consistent as I can be."
Kelly Clarkson
The Grammy winner explained how moving to New York City helped kickstart her health and fitness journey. "Walking in the city is quite the workout," Kelly told People in an interview published Jan. 3. "And I'm really into infrared saunas right now. And I just got a cold plunge because everybody wore me down."
Julianne Hough
Julianne told E! News the exercise she always blocks out time for when she has a jam-packed schedule.
"I know that I can walk around the hills with my dog," the Dancing With the Stars said. "That's key because I have to get her out, too. But movement in general, whether it's 10 minutes or five minutes of something, I have to move my body."
And when she has more time to break a sweat, she added, "Whether it's a Kinrgy class or doing Pilates or yoga, the fact that we get to combine all of those modalities is my favorite because I love versatility."
Kate Hudson
"I always move, even for a few minutes each day. Sometimes I'll go into a room, turn up the music and just dance. It's a great way to let loose and feel great."
DJ Khaled
The record producer opened up about his love for golfing and how it's helped him slim down.
"I do it every day and I get a chance to sit on the golf cart or walking about to answer an email or a call and handle my business," he told Us Weekly in an interview published Sept. 20. "It's so much [more] pleasurable, meaning [being around] the nature, the sun. It cleanses me."
Lana Condor
"Honestly, my favorite way to break a sweat right now is playing VR. We got a virtual reality headset right as everything was shutting down and it's been AMAZING during quarantine. There are so many games that make you work up a sweat and it's so awesome. I am genuinely so sore after I play."
Padma Lakshmi
"Under normal circumstances it's going to the gym, but right now I'm taking online classes with my Pilates instructor Britni Lariviere. I'm also trying to jump rope—2,000 strokes each day."
JoAnna Garcia Swisher
"Family bike rides are big for us right now and I always try to carve out thirty minutes for pilates with Andrea Rodgers and foam rolling with Lauren Roxburgh."
Janel Parrish
"Running and listening to music. The best outlet I've found these last few months being stuck in the house! I feel so great and pumped up after."
Dascha Polanco
"My favorite way to break a sweat is mix of sex, PRx Performance, hiking, biking."
Brooke Burke
"By connecting with my audience and motivating them through my Brooke Burke Body fitness app! I've been live streaming on the app as well as on my Instagram since the beginning of quarantine in an effort to make fitness fun and innovative. I especially love walking my viewers through total body cardio parties, which is when I crank up the music, let them find their rhythm and let the booty burn. Cardio kicks up your heart rate, so if you're not sweating, you're not working out hard enough!"
Whitney Port
"I have been doing a lot of Sculpt, Cardio Boxing and Yoga Classes on the obé Fitness App and virtual classes with Pilates By Amanda. If I don't have a lot of time, I will do Lauren Gores' express workouts on her Instagram."
Maggie Q
"During lockdown it's yoga under my own direction. I can go onto so many different tangents and by the time I am done it is often two hours."
Merle Dandridge
"My trainer, Amoila Cesar, gets lots of results out of me by appealing to my 'no quit,' competitive side. He yells and I love it. During quarantine, I got my fix by doing his 6 Weeks of THE WORK on Beachbody on Demand. I also love a rigorous barre class and need daily yoga."
Rachel Naomi Hilson
"I've been doing a lot of dancing in my apartment. I'll turn on some music and just go. Sometimes it's more structured, sometimes it's interpretive, sometimes I twerk. Also hiking!"
Paige DeSorbo
"My go-to work out is P.Volve, I've gone to their classes for years and now I stream them at home. I try and workout at least 3 to 4 times a week even if its for 30 minutes. Its all about strengthening and elongating your muscles. It's my favorite!"
