Top 10 Female Fitness Influencers of 2025

In 2025, female fitness influencers are more diverse than ever – spanning mega stars to micro influencers, across Instagram, TikTok, YouTube and beyond. Notably, a rising emphasis on micro-influencers (those with roughly 10k–100k followers) is reshaping the fitness scene. These creators may have smaller followings, but they often boast higher engagement, niche community trust, and authentic connections that brands crave. Many are savvy in e-commerce – from leveraging the Amazon Influencer Program and hosting live shopping streams, to launching their own product lines or collaborating on fitness gear. Crucially, they excel at producing user-generated content (UGC) that feels real and relatable, which can be repurposed by brands for marketing. Platforms like Stack Influence (an influencer marketing platform empowering micro creators) have emerged to connect these content creators with brands, including D2C companies and Amazon sellers, to scale campaigns with influencer-generated content. In short, fitness influencers in 2025 aren’t just posting workouts – they’re driving trends in social commerce, blending personal branding with product promotion in a way that resonates with today’s consumers.

Below, we spotlight the top 10 female fitness influencers of 2025 (all U.S.-based), featuring a mix of influencer tiers. Each has a unique content style and platform focus, from Instagram and TikTok phenoms to YouTube trainers. We’ll note key metrics (followers, engagement), their e-commerce endeavors (Amazon storefronts, product collaborations, etc.), and UGC strengths. Whether macro or micro, these women are killing it in the fitness space – inspiring audiences to get moving while skillfully blending fitness with social commerce.

Her Instagram posts showcase gym workouts, healthy lifestyle tips, and personal reflections, fostering a tight-knit community. Despite her massive reach, Whitney maintains a ~2–3% engagement rate on IG – solid for a mega influencer, thanks to her relatable personality and genuine interaction with fans.

She’s also a longtime Gymshark ambassador, even co-designing Gymshark x Whitney collections of activewear. These collaborations have been wildly popular, often selling out due to her loyal following.

Her content is highly valuable as UGC; many of her professionally shot workout demos can double as promotional content for fitness brands. In fact, her polished yet real style embodies why micro and mid-tier influencers are prized – high-quality, relatable content that drives engagement and inspires viewers to actually use the products and workouts she shares.
  

3. Krista Pool (“Stay Fit Mom”)

Krista Pool – known on Instagram as @stayfitmom_krista – has carved out a niche at the intersection of fitness and nutrition for busy moms. With 1.1 million Instagram followers, Krista is a mega influencer who emphasizes realistic wellness. She’s famous for her “Macro Friendly” recipes and meal plans that help followers enjoy delicious food while hitting their fitness goals. In fact, Krista offers her own Macro Friendly Cookbooks and a Monthly Macro Meals subscription service for healthy recipes.

This value-added content has helped her build a strong community (particularly among moms) who trust her advice.

• Platforms: Krista’s primary platform is Instagram, where she posts high-quality photos of meal preps, quick workout snippets, and transformations. She’s also active on TikTok (her recipe videos and mom-life fitness hacks have garnered thousands of likes) and she runs a blog on StayFitMom.com. Her engagement is solid given her large audience (around ~1% on IG), and she encourages follower interaction with challenge hashtags and Q&As about macro tracking.

• E-commerce & Collaborations: As a fitness influencer deeply involved in e-commerce, Krista leverages multiple channels. She has an Amazon storefront highlighting kitchen gadgets, supplements, and home gym equipment she uses – effectively turning her recommendations into a shoppable experience. Krista also sells digital products (the cookbooks and macro programs) through her website and Amazon Kindle. These products often rank well on Amazon due to her large follower traffic. As a micro-entrepreneur, she’s shown how an influencer can evolve into a seller: her personal brand now includes merchandise like meal prep containers and workout planners. The authenticity of her content (she often shares family photos and personal fitness struggles) means her product endorsements come off as friendly advice, a form of UGC that followers readily trust. By focusing on a specific niche (macro nutrition for women) and consistently delivering value, Krista Pool has become a top influencer who drives both inspiration and product sales in 2025.
  

4. Bianca Williams

Bianca “Bee” Williams brings style to the fitness world. A fitness influencer and actress based in Los Angeles, Bianca has around 400K Instagram followers and a vibrant presence on TikTok. What sets her apart is her fusion of fitness and fashion – she’s often seen rocking trendy workout outfits and athleisure looks. Bianca became a prominent Amazon Fashion influencer, showcasing affordable activewear finds with her audience. Her Instagram bio even highlights this multi-hyphenate role: “Amazon Fashion | Fitness | Actress”. Fans love her try-on hauls and gym outfit ideas; one of her recent posts featuring an Amazon ribbed two-piece set garnered nearly a thousand comments from followers loving the look. Bianca’s engagement is strong, with lively comment sections – she’s very responsive to her community, which strengthens trust.

• Platforms: Instagram is Bianca’s main platform for polished photos and Reels (workouts, outfit inspiration, and lifestyle content). She also uses TikTok for more candid clips, like quick OOTD (outfit of the day) videos and comedic fitness skits. Additionally, Bianca is a rising star on Amazon Live, Amazon’s streaming platform where influencers demo products in real-time. Her live streams (often in partnership with brands or during Amazon’s special sale events) allow her to showcase workout gear or beauty products while interacting with viewers – a powerful e-commerce tool that blends entertainment with shopping.

• E-commerce & Collaborations: E-commerce is at the heart of Bianca’s influencer career. She runs a popular Amazon Storefront curating her favorite fitness, beauty, and lifestyle products – essentially a personalized shop where followers can find all the items she uses and loves. From yoga mats to sports bras to skincare, if Bianca has it, you can bet it’s linked on her Amazon page. This has made her an influential recommender for Amazon’s activewear category. Brands have taken notice: she’s collaborated with activewear companies and even mainstream brands like Carhartt (showing how to style workwear for workouts). Bianca’s ability to generate sales is proven by her frequent appearance on Amazon’s own social channels and her involvement in programs like Amazon’s #FoundItOnAmazon fashion finds. By combining her passions – fitness training and fashion – she’s created a relatable persona that motivates followers to both exercise and shop her looks. For brands, her content serves as high-quality UGC: stylish, aspirational, but still down-to-earth content that drives product discovery and purchase.
  

5. Paulina Hefferan

Paulina Hefferan (@paulinastein on IG) may have under 100K followers, but as a celebrity trainer and nutritionist she carries big influence in elite circles. Founder of her own fitness program Reset by Paulina, this wife and mom of three balances wellness, beauty, and motherhood content on her platforms. Paulina’s Instagram (≈99K followers) showcases her training routines (sometimes featuring the celebrities she coaches, adding social proof), nutrition tips, and glimpses of her family life. Her niche is holistic fitness for women – think functional workouts, postpartum fitness, and self-care. With an engagement rate above average (her posts often get hundreds of comments from her tight-knit community), Paulina exemplifies how micro influencers can foster strong relationships with followers. Many fans view her as both an expert and a friend, regularly seeking her advice in comments and DMs.

• Platforms: Instagram is Paulina’s primary hub, where she posts workout videos, client transformations, and motivational quotes. She’s also active on Facebook and occasionally on YouTube for longer talks or Q&A sessions. While not a TikTok phenom, she repurposes some content to TikTok, focusing on quick fitness tips. Her relatively smaller follower count belies her impact – her audience is very targeted (women interested in serious training and nutrition), so brands in that niche get great ROI working with her.

• E-commerce & Collaborations: Paulina’s influencer journey is intertwined with entrepreneurship. Her Reset by Paulina program is an e-commerce venture in itself – offering paid challenges, coaching packages, and downloadable meal plans on her website. This means she’s not only creating content but directly selling fitness services to her followers. Additionally, Paulina has an Amazon Influencer profile, where she lists recommended products (from protein powders to yoga mats). She often partners with fitness apparel and supplement brands on sponsored posts; however, she’s selective, aligning only with products she genuinely uses in her training of clients. This selectivity boosts her credibility. As a result, when she does promote a product, her followers know it’s trustworthy – basically gold in terms of UGC value for the brand. For example, a simple Instagram video of Paulina using a particular resistance band can drive notable sales, because her audience knows it’s part of the regimen she uses with high-profile clients. Paulina Hefferan illustrates how micro influencers at the top of their field can leverage expertise into both community influence and commercial success, all while keeping content authentic.
  

6. Amanda Nigg (“Farm Fit Momma”)

Amanda Nigg, known as FarmFitMomma, brings a breath of fresh country air to fitness influencing. A farm wife and mom from the Midwest, Amanda has about 55K Instagram followers and a growing TikTok presence, drawn to her unique blend of farm life and workout content. She’s the founder of Farm Fit Training, a program tailored for people in rural lifestyles. Amanda’s mantra is all about “no excuses” – she often incorporates farm chores and equipment into creative workouts (e.g., lifting hay bales for strength, using feed sacks for resistance). Her authenticity (muddy boots and all) and humor have earned her features in both fitness and agriculture communities. In her TikTok videos, she’ll deadlift tractor parts or do squats in a barn, making fitness fun and accessible to those who might not have a fancy gym. This innovative content has garnered thousands of likes and shares, turning heads both in farming circles and among urban folks who find her content refreshingly real.

• Platforms: Amanda is active on Instagram, where she shares daily life on the farm, motivational posts, and quick workout demos (often with her kids or farm animals making cameo appearances!). TikTok is another strong platform for her, as her short-form videos of “farm workouts” have gone viral for their novelty and relatability. She has a smaller YouTube channel and a blog on FarmFitMomma.com where she writes about balancing family, farming, and fitness. Her engagement rate is notable – her posts spark genuine conversations, from fellow moms thanking her for home workout ideas to farmers appreciating her focus on physical and mental health in agriculture.

• E-commerce & Collaborations: As a micro influencer, Amanda has cleverly capitalized on a niche that overlaps wellness and farming. She sells Farm Fit merchandise (think humorous workout tank tops with slogans like “Straight Outta the Barn”) and offers an online coaching subscription for her Farm Fit Training program. On the e-commerce front, she’s an Amazon Associate and showcases practical fitness gear for home workouts – many of which she uses in her videos. For instance, she might demonstrate a workout using affordable dumbbells or a particular brand of work gloves, then direct followers to her Amazon shop to purchase those items. Amanda also collaborates with brands that resonate with her dual niche: fitness brands like supplement companies, as well as farm-oriented companies (she’s done campaigns emphasizing physical wellness for farmers). One of her impactful partnerships was with an agricultural safety organization, creating content on injury prevention through fitness – a unique angle that underlines her credibility. Amanda’s content is essentially made-for-UGC: raw, unfiltered, and highly authentic. Brands who repost her videos or photos get an instant injection of realness and creativity. In 2025, “Farm Fit Momma” exemplifies the power of micro influencers – she might not have the largest following, but her influence runs deep in a passionate community that spans beyond the traditional fitness crowd.
  

7. Lizzie Martinez

Lizzie Martinez (@lizzieifbbpro) is an IFBB Pro bodybuilder and fitness coach making waves both online and offline. With about 49K Instagram followers, Lizzie’s reach is firmly micro-tier, but her impact is significant. She owns Sun City Athletic Club, a gym where she trains clients in person, and she shares this journey with her online followers. Lizzie’s content often features clips of her working out at her gym, coaching gym members, and juggling fitness with family life (she often mentions balancing being a mom/wife with being an athlete). Her motto is helping women live a healthy lifestyle at any stage – reflecting faith and positivity (she frequently shares a motivating Bible verse along with fitness tips). As an IFBB Pro, Lizzie also competes, so she brings her audience behind the scenes of contest prep, diet, and the discipline of bodybuilding. This mix of competitor credibility and approachable gym-owner vibe makes her relatable – she’s simultaneously an elite athlete and the friendly coach next door. Her engagement is strong; posts garner lots of questions about workouts and diet, which she diligently answers, reinforcing her role as a mentor.

• Platforms: Instagram is Lizzie’s main platform, packed with workout videos (from weightlifting PRs to beginner tutorials), transformation photos of her clients, and personal reflections. She leverages Instagram Stories to give day-in-the-life peeks – running the gym in the morning, family time in the evening, etc. Lizzie also uses Facebook to engage with a local audience (promoting gym events or challenges). While not hugely active on TikTok yet, she has posted a few fun workout challenges there too.

• E-commerce & Collaborations: Lizzie’s dual role as an influencer and gym owner means she’s deeply embedded in fitness commerce. She has sponsorships – notably, she’s a brand ambassador for BSN Supplements (a popular sports nutrition brand). She often features BSN products (like protein powders) in her posts, giving genuine reviews and recipes, which drives sales through her affiliate links. Additionally, Lizzie likely has an Amazon storefront where she lists her favorite training gear and supplements, capitalizing on her followers’ trust in her recommendations. At her physical gym, she sells merchandise and branded equipment, which she also promotes online (for example, showcasing her gym’s apparel line on IG and linking to purchase). Lizzie’s content serves as great UGC for these brands: a video of her deadlifting with a certain branded barbell or using a BSN protein shake as part of her routine both acts as authentic advertising. Importantly, her involvement in the community (mentoring women, hosting fitness workshops) means any product she backs comes with a story of how it benefits real people at her gym. In a nutshell, Lizzie Martinez demonstrates that micro influencers who combine on-the-ground expertise with social media savvy can drive meaningful engagement and commerce in the fitness industry. She’s inspiring women to get strong, whether online or in person, and doing it with a business-minded flair.
  

8. Kahdia

Kahdia (known as @kahdiaaa on Instagram and TikTok) represents the new wave of young micro influencers blending fitness, lifestyle, and savvy online marketing. Based in Miami, 25-year-old Kahdia has about 28K Instagram followers and an impressive 8.3% engagement rate, indicating a highly active audience for her size. She creates content around workouts, weight loss, and gym fashion (“gym fits”), targeting fellow young women on fitness journeys. Kahdia’s style is vibrant and relatable – one day she’s posting a glute workout tutorial, the next she’s showing a mini-haul of cute Amazon activewear. What sets Kahdia apart is her fluency in social commerce: she’s part of the generation of influencers who seamlessly integrate affiliate marketing into their content. She uses platforms like LiketoKnow.it (LTK) to share shoppable outfit links and is an avid participant in Amazon’s influencer program. Essentially, she’s a content creator who makes it easy for followers to shop her posts, turning her social feed into an interactive catalog of fitness inspiration.

• Platforms: Kahdia is cross-platform: very active on TikTok (where quick workout videos, “what I eat in a day” clips, and before-and-after weight loss snippets have earned her a solid following) and on Instagram for more polished photos and Reels. On TikTok, her content often goes viral within niche fitness circles because it’s upbeat, set to trending music, and features realistic progress (e.g., showing her own fitness transformation over time). On Instagram, she engages her audience with Q&As and motivational captions, building a tight community despite being micro-scale. Her audience demographics (mix of men and women 16-44) show she appeals broadly, but she especially resonates with young women of color, as she often shares her personal experiences and cultural flair in fitness.
• E-commerce & UGC: E-commerce is core to Kahdia’s content strategy. She actively promotes her Amazon storefront and LTK shop in her bio, signaling followers that they can “shop my looks” easily. For instance, if she posts a video in a stylish gym outfit, she’ll list where each item is from and often include affiliate links or discount codes. She’s collaborated with athleisure brands for sponsored posts, and her high engagement means those posts tend to perform well (a big plus for brands looking for both reach and interaction). Kahdia’s knack for creating content that feels organic while showcasing products is essentially UGC gold. Brands often re-share her posts because they strike that balance of aspirational yet attainable. One notable aspect is her transparency; she often thanks her followers for supporting her links (which earn her small commissions), creating a sense that her community is helping a friend, not just “a creator”. This transparency and authenticity amplify trust. By empowering her audience with fitness knowledge and style tips, Kahdia exemplifies the 2025 micro influencer who is part coach, part trendsetter, and part entrepreneur. Keep an eye on her – micro influencers like Kahdia are on the fast track to greater fame, and they’re doing it by aligning fitness and e-commerce in a genuinely synergistic way.
  

9. Melissa Bender

Melissa Bender (@benderfitness) might not have the largest following, but her impact on the online fitness community is undeniable. An occupational therapist turned fitness blogger, Melissa has been sharing workouts online for over a decade. She has 23K Instagram followers – a humble number – but her website BenderFitness.com has reached millions of people with over 1,000 free workout routines. Melissa champions accessible fitness: her ethos is that you don’t need a fancy gym or expensive program to get in shape. She provides full-length workout videos (often filmed in her living room) targeting everything from HIIT and yoga to prenatal fitness, all available at no cost. This generosity has earned her a loyal global following (fans often call her the “queen of home workouts”). She complements the free content with a subscription Members section for those who want more structure, showing a smart balance of free value and monetization. At 23K IG followers, Melissa is definitely a micro influencer, but she punches above her weight through the depth of content she offers and the trust she’s built by consistently delivering results for her followers.

• Platforms: Melissa’s primary platform is her blog and YouTube channel, where users access her vast library of workout videos. Her YouTube channel has a modest ~90K subscribers, but the views on popular videos are in the hundreds of thousands, indicating many tune in without necessarily “subscribing.” On Instagram, Melissa shares daily workout move clips, motivational quotes, and snapshots of her life (including being a mom). Her engagement is solid – posts often receive lengthy comments where followers share their fitness progress or thank her for specific programs. Melissa also uses Facebook groups to host fitness challenges, fostering a community feel among participants. She may not be a TikTok native, but some fans repost her content there, extending her reach indirectly.

• E-commerce & Collaborations: As a pioneer in free online fitness, Melissa’s model has been more about content sponsorships and ad revenue than flashy brand deals. However, she does partake in affiliate marketing for products she personally uses – for instance, linking to Yoga mats or dumbbells on Amazon via her blog, so followers can find the exact equipment she uses. Her Amazon influencer page likely lists her go-to gear, which meshes perfectly with her workout posts (e.g., if a routine requires a resistance band, she’ll mention the one she uses and where to get it). In recent years, as UGC has gained value, Melissa has collaborated with a few fitness apparel and wellness brands to create sponsored content. These partnerships are always clearly disclosed and thoughtfully integrated – a video sponsored by a sneaker company, for example, will still deliver a legit 20-minute cardio routine (so viewers get value even if they aren’t interested in the shoes). Brands appreciate Melissa for her reputation: any content she produces carries a seal of trust, since she’s known for no-gimmick, effective workouts. In terms of UGC, her vast library of high-quality workout videos is a treasure trove – and indeed, some equipment brands have hired Melissa to create workout content featuring their products, essentially doubling as promotional material. For anyone looking up “free home workout 2025”, chances are they’ll stumble on Melissa Bender. She embodies how a passionate micro influencer can cultivate a massive impact through consistency and authenticity, turning content creation into a thriving career.

10. Rachel Cooper

Rachel Cooper (@rc__fitness) is a rising fitness influencer who bridges the gap between traditional fitness coaching and the new world of live-stream commerce. With 14.4K followers on Instagram, Rachel is firmly a micro influencer, but her influence extends beyond IG. She is a certified personal trainer and notably an official Technogym Master Trainer, meaning she’s an expert at using Technogym’s high-end fitness equipment. In 2025, she leverages this role on Amazon Live, where she’s an Amazon Live Creator hosting shoppable live workouts and product demos. Imagine tuning into a live session where Rachel guides you through a home treadmill workout – while viewers can click to view the treadmill on Amazon in real time. This innovative format has made Rachel a key personality in the fitness-tech space. Her content on Instagram includes motivational quotes (often faith-based, reflecting her “The Lord is my Strength” mantra), clips from her live sessions, and training tips. Given her smaller follower count, Rachel’s engagement is very high – many of her posts turn into mini forums, with followers (many of whom are clients or class participants) discussing their progress.

• Platforms: Amazon Live is where Rachel truly shines. She hosts regular live broadcasts, sometimes in partnership with brands or for Amazon’s special events (Prime Day fitness showcase, for example). These lives can attract thousands of viewers, far beyond her follower count, since they appear to anyone browsing fitness products on Amazon. On Instagram, Rachel uses the platform to announce upcoming live sessions, share highlights, and post educational content (like how to use certain gym equipment properly, or quick workout routines people can try at home). She also uploads longer workout videos to YouTube and engages with her audience in the comments – extending her coaching beyond the live sessions.

• E-commerce & Collaborations: Rachel is deeply involved in e-commerce through Amazon Live. By being a fitness influencer who actually helps sell products in real time, she’s part of Amazon’s push into influencer-driven shopping. She likely earns commissions or fees for product sales generated during her streams. In addition to Technogym (with whom she’s closely affiliated), Rachel collaborates with various fitness gadget and apparel brands that feature in her live sessions. For example, she might host a “home gym setup” live, showcasing an adjustable dumbbell set, a yoga mat, and a workout bench – all of which are linked for purchase. Her followers appreciate that she demonstrates products and answers questions on the spot, which builds trust that can be missing in static product listings. Outside of Amazon, Rachel also contributes to the Technogym community by creating content for their app and appearing at fitness events as a master trainer, which elevates her profile. From a brand’s perspective, Rachel’s expertise and her comfort on camera make her an ideal UGC creator – her demos and reviews come across as professional yet genuine. In fact, some of her Amazon Live recordings are repurposed by brands as tutorial videos on their own product pages. As fitness increasingly intersects with tech and online shopping, micro influencers like Rachel Cooper are leading the way, proving that you don’t need millions of followers to make a big impact – you just need the right platform and authentic engagement.
  

Comparative Snapshot: Platforms, Engagement & E-commerce Tie-Ins

To wrap up, here’s a quick comparison of these top 10 influencers – highlighting their primary platforms, follower counts, engagement rates, and how they blend content with commerce:

(Engagement rates for some micros are estimated based on typical performance; sources provided where available.)

Key Takeaways for 2025 Fitness Influencer Marketing 🚀

• Micro Influencers = Big Impact

As shown, over half of our top 10 are micro influencers under 100K followers. They often see higher engagement and trust within their niche communities, leading to better conversion rates for brands despite the smaller audience. In fact, micro and even nano influencers have become go-to partners for niche e-commerce brands and Amazon sellers, offering authentic word-of-mouth at scale. Don’t underestimate the “small” creators – their influence is mighty in 2025.

• Multi-Platform Presence

All these influencers are active on multiple platforms – typically a primary (Instagram or YouTube or TikTok) and at least one secondary. This multi-channel approach not only increases their reach (catching different demographics on different apps) but also creates a content ecosystem (e.g., a YouTube workout video promoted via Instagram stories). For maximum impact, brands should engage influencers across platforms and formats (posts, Stories, Lives, etc.) to tap into their full audience.

• UGC and Authentic Content are King

A common thread is authenticity. Whether it’s Whitney’s candid mental health chats or Amanda’s muddy farm workouts, genuine content wins hearts. Brands are shifting away from overly produced ads to more organic user-generated content. Influencers who produce high-quality UGC – like Sydney’s professional workout videos or Kahdia’s relatable TikToks – are in high demand. This content not only engages on the influencer’s feed but can be repurposed by brands in ads, product pages, and social media, blurring the line between influencer content and brand content.

• E-commerce Integration

2025’s fitness influencers are savvy entrepreneurs. Many have their own products or affiliate stores (Amazon storefronts, apps, merch) and are fluent in monetizing via social commerce. For example, Bianca and Rachel use Amazon Live and storefronts, effectively turning content into instant shopping experiences. The lesson for brands: meet consumers where they are. Partner with influencers in ways that make shopping seamless – promo codes, direct links, live demos – capitalizing on the impulse when a follower is inspired by content. This integration of content and commerce is driving higher ROI from influencer campaigns than ever before.
