Key Takeaways
- Senada Greca traded motivation for discipline, and discipline is what carried her from crisis to Kim Kardashian’s trainer.
- Greca turned the hardest chapter of her life — depression, an eating disorder, raising her family at 14 — into the exact expertise her business is built on.
Many of the best entrepreneurs turn their biggest weaknesses into their greatest strengths. Celebrity trainer and wellness entrepreneur Senada Greca is a perfect example. After struggling with depression, anxiety and eating disorders early in life, Greca went on to become one of the world’s leading voices in wellness, training megastars like Kim Kardashian, building a following of more than 10 million across platforms, and founding multiple wellness companies, including Aonic and WeRise.
All it took was a mindset shift.
Turning struggles into strength
Greca grew up under a communist regime in Albania, where her family faced hardships including food scarcity. She moved to the U.S. at 14, where she experienced a massive culture shock.
“I was stepping into womanhood during that time, so I went from scarcity in a communist country to now plentitude of different things, and responsibilities changed,” she shares. “Now I was the only one in the family that spoke English and had to kind of carry the family at 14. And that started eating disorders, depression, anxiety.”
Rather than succumb to those negative thoughts, Greca found an outlet in fitness and eventually learned the power of healthy eating and strength training.
She shifted her mindset from trying to be as skinny as possible to becoming as strong as possible, and replaced motivation with discipline.
“Motivation is a feeling,” Greca explains. “It’s transient. We feel like working out today. We might not feel like working out tomorrow. But when you build that discipline day in and day out, that’s what carries you through when motivation is lacking.”
Eventually, she applied that same philosophy to her career.
“I very much liken building a strong body to building a strong business, but on a much bigger scale,” she says. “It’s pushing through those tough days, making those tough decisions, showing up when you absolutely don’t want to.”
Greca’s fitness journey started as a pursuit of personal improvement. But once she realized how much better her new lifestyle made her feel, she felt compelled to share it with others, posting workouts and fitness tips on social media. At the time, fitness was still a hobby, not a career. Greca holds an MBA and had previously worked in finance and sales, filming workouts for Instagram in her spare time. As her following grew, she saw an opportunity.
“I’ve always wondered, would my training methods work for somebody else?” Greca shares. With her newfound success on social media, the answer seemed to be yes. She decided to take it a step further and founded her first company, WeRise.
“WeRise was taking that philosophy that I built for myself,” Greca shares. “Helping women step into the strongest version of themselves, and not just physically, but mindset as well. Overcoming traumas, overcoming imposter syndrome, overcoming career development problems that they had.”
It started as a standard fitness app, but has since evolved into what Greca describes as “your partner in transformation,” combining strength training, personal coaching from Greca, nutrition tips, and a built-in community designed to keep users accountable. In many ways, it’s like having a virtual gym in your pocket.
The concept took off, and alongside Greca’s rapidly growing social media presence, it caught the attention of one of the world’s biggest celebrities: Kim Kardashian.
The Kardashian connection
Kardashian discovered Greca through social media and was impressed by the years of work showcased in her online portfolio. The two connected, and Kardashian eventually hired Greca as her personal trainer, one of the most high-profile behind-the-scenes jobs in Hollywood.
“She appreciated my discipline, my story, and what I’d accomplished, so that’s how she found me,” Greca recalls. “I like to say that you can’t control who discovers you or your work, but you can control what they find when they do. So when that opportunity came, I was ready for it. I didn’t chase it, but it happened, and I’m glad it did because it introduced me to so many opportunities that I’m incredibly grateful for.”
Greca adds that she’s training Kardashian with the same methods she uses on the We Rise app, which Kardashian recently shared on social media during Greca’s September workout challenge.
Working with Kardashian gave Greca an even bigger platform and added credibility with an audience eager to learn about the celebrity’s workout and nutrition habits. That experience partially inspired Greca’s next venture, Aonic.
Wanting to show people the reality behind her own routine, Greca founded Aonic as a science-driven supplement company focused on educating consumers about wellness.
Greca has never directly asked Kardashian to promote her businesses, but organic opportunities have arisen nonetheless. “Kim has shown this before on social media, she loves Aonic,” Greca says. “She loves creatine, Aonic build, and the Aonic fuel, especially the cans.”
Ending the markup
Kardashian’s enthusiasm reflects a broader cultural trend.
“I kept seeing people who wanted to take care of themselves in a much better way through supplementation, but without the confusion and stress,” Greca shares. “There’s so much confusion when it comes to health and wellness, especially with healthcare optimization. I think sometimes that confusion is created so people can sell you something. With Aonic, we wanted to simplify that.”
That philosophy is summed up in Aonic’s motto: “end the markup.” Greca believes the wellness industry has become saturated with premium products and prices, often adding costs that have little to do with the quality of what’s inside. Aonic aims to take a different approach.
“We’ve changed the economics of the category itself because it’s gotten so packed with premium brands,” Greca explains. “They’re adding different ingredients so they can justify the premium prices. We didn’t want to become another brand like that. We wanted to end that premium pricing, which incorporates all of the marketing, advertising, logistics, and warehousing.”
Instead, people can join the Aonic Club, pay an annual membership, and get products at cost. “This way the quality stays, and the markups get ditched,” Greca proclaims.
AI powers part of Aonic’s effort to reduce prices, which Greca believes should lower costs for consumers, not just increase profits for companies.
“I don’t know that I love AI, to be honest with you, or where some things could potentially be heading,” she says. “But if we utilize it smartly, I think we can use it with Aonic to cut costs across sourcing, operations, manufacturing, finance, and branding, and bring those savings to the consumer. AI is being used in Silicon Valley to make companies loads of money, but nobody is really thinking about how it can reduce costs for consumers. I think we’re leading that effort, especially when it comes to supplement brands.”
Building beyond herself
Unlike many influencers who build brands around their personal identities, Greca doesn’t want herself to be the main focus of her companies.
“I want the brands, whether it’s WeRise or Aonic, to grow beyond my relevance,” Greca shares. “I want them to encompass everything wellness while staying true to the standards of quality we’ve established in these early stages. I want to keep those standards as we grow, keep the products affordable and accessible, and continue using innovation, AI, and technology not to enrich our own pockets, but to pass those savings on to the consumer and help people take better care of themselves.”
Greca became emotional as she reflected on the bigger mission behind her companies.
“It’s not, ‘How can I make as much money as possible?’ It’s, ‘How can I help as many people as possible in the best way possible, in the most accessible way possible?’” she says. “Because, again, like I’ve said before, if you try to capitalize on the trust of people with every single thing that gets thrown at you, you’re eventually going to deplete that trust fund, as I call it.”

Effective product pages help online shoppers decide whether an item fits their needs and what buying it involves. A beautiful photograph gets attention. Product details such as dimensions, available sizes, delivery details, and a clear price help turn that attention into a purchase.
Even established retailers miss these basics. In its benchmark of leading U.S. and European retailers, updated in March 2026, Baymard Institute rated 52% of desktop sites and 62% of mobile sites “mediocre or worse” for product-page usability1.
Product-page changes can affect revenue, too. In a 27-day test for Life Pro Fitness, agency Media Contour made product images, key details, and buying buttons visible without needing to scroll. Testing vendor Wingify reported that the revised page generated $0.67 more revenue per visitor than the original2.
If you are building a new store, follow the five tips below as you create your product pages. Have those pages ready before running ads that send shoppers to them.
If you already have an online store, choose one product page to improve. Reference these steps to check whether it answers shoppers’ questions and lets them add the right item to their cart.
1. Answer shoppers’ questions in the product description
Identify the main question a shopper needs answered before buying. Look for questions customers ask repeatedly or misunderstandings behind returns. For a new product, start with fit, compatibility, or what is included. Confirm the answer against your product specifications, then put it near the start of the description.
For example, consider a pet-supply retailer selling a dog harness. Someone choosing their first harness needs measurements and adjustment details to judge the fit. Someone replacing a harness they already own needs to recognize the same model and size. The page should make both tasks straightforward.
Also, use consistent labels and units across similar products to make comparisons easier. Include limitations, such as incompatible models or items sold separately, so shoppers can rule out an unsuitable purchase.
In e-commerce platform BigCommerce, for instance, online sellers can use the product description and custom fields—additional facts such as material or compatibility—to present these details. Preview the product page to check that shoppers can find the information they need.
Then, use those same facts to help shoppers recognize the item in search results. In BigCommerce’s page title field, use the product name and a relevant detail, such as its model or material. Avoid repeating keywords or giving every product the same title.
2. Give every product image a question to answer
Plan your gallery around what someone needs to inspect. Show the whole product, a useful detail, and the product in use. For example, a lighting retailer could photograph a lamp beside a chair to show its scale and how it lights a reading space. A close-up of the switch shows how someone would operate it. Together, these images help shoppers picture using the lamp at home. Keep written dimensions available as well.
The same Baymard overview describes how shoppers use images to judge size and can struggle when photographs lack a familiar reference.
If you sell a bundle, make clear which pictured items are included. For products that need assembly or demonstration, you might even consider creating a short video. Add alt text: a short description of the useful information in an image. Screen-reader software can read that description aloud or present it in braille. Keep essential instructions available as text as well.
BigCommerce supports product images, images for variants such as different colors, and YouTube-hosted product videos. Check that your gallery presents the right item as shoppers change their selection.
3. Make choices, prices, and recurring charges clear
Keep size, color, quantity, and purchase options close to the buying button. Label them plainly, show the current selection, and make unavailable choices recognizable. If the size options fit on the screen, show them as labeled buttons, such as S, M, and L. This lets shoppers see which sizes are available without opening a menu, as the Baymard overview explains.
Place helpful links beside the choice it explains. For the dog harness, for example, consider putting a measurement guide beside the size selector so shoppers can check the fit before choosing. Keep it visible or provide a clearly labeled link that works by touch and keyboard.
In BigCommerce, online sellers can configure choices such as size and color through product variants and options. Then check that the displayed price and availability match the shopper’s selection. For multipacks, show both the pack total and the unit price. Make the full pack price easy to find so shoppers know what they will be charged.
If you offer subscriptions, let shoppers explicitly choose between a one-time purchase and a recurring order. Put the recurring charge, delivery frequency, and change or cancellation terms beside that choice so shoppers can compare the commitments before selecting. Confirm that these terms match how your subscription service works. Select a subscription yourself and verify that checkout shows the plan, price, and frequency you chose.
4. Make sure delivery, returns, and reviews are easy to find
A shopper who needs an item by a particular date wants to know whether it will arrive in time. Show a delivery estimate for their destination. Put a short explanation of shipping and returns near add to cart, with links to the full policies.
Show shipping fees or explain how they will be calculated. Clearly describe return windows, fees, and exclusions that matter for the item. If pickup is offered, distinguish stock at the selected location from stock elsewhere. Avoid presenting an estimate as a confirmed promise.
Also consider making reassurances that are specific to the purchase. Using the dog harness as an example again, you’d want to explain whether a shopper can exchange it if the fit is wrong and which conditions apply. That answers the practical concerns that a badge saying “Shop with Confidence” leaves unresolved. Use only promises your business can honor.
Customer reviews provide another way to assess the product. Show the review rating, text, reviewer’s display name, and date on the relevant product page. If reviews come from another service, name that service. These details help shoppers understand whose experience they are reading and how recent it is.
5. Test the path from product page to cart
Shoppers need to know that the page has registered their choices and whether adding an item succeeded. Open your chosen product page on your phone. If a required option starts unselected, try adding the item before choosing it. The page should tell you what to select or explain why “Add to cart” is unavailable.
If the product has options, choose them, then change one selection. Check that the price, availability, and any option-specific images match. Add the item. While the request is processing, the page should make that clear. Once it succeeds, a confirmation or the cart itself should show what was added. If an error occurs, it should explain how to continue without losing other selections.
From there, make sure to check the item’s quantity, options, and price in the cart. If you chose a size or color, return to the product page and check whether it still shows that selection. These checks help catch a wrong selection or an uncertain result before a shopper encounters it.
Shoppers who cannot use a mouse need to select options and add products using a keyboard. To check that they can, repeat the steps above on a computer without the mouse. Use Tab to move forward between controls and Shift+Tab to move back. A visible outline or other marker should show which control you are about to use. Press Enter to activate links and Enter or Space for buttons. In a drop-down list, such as a size selector, use the arrow keys to move through the options.
Shoppers who need larger text must still be able to read product details and reach Add to cart. Use the browser’s Zoom control to enlarge the page to 200% and try the same steps again. Check for overlapping text or controls that disappear. Across all these checks, record anything that prevents choosing the product, adding it, or correcting a mistake.
Keep improving one page at a time
Clear facts and images help shoppers judge the product; clear choices, terms, and working controls help them act on that decision. Choose one issue from your review to fix first. Give priority to a problem that prevents adding the correct item to the cart. If shoppers can add the correct item, address an unanswered question that could lead someone to buy the wrong product.
Record what you changed and when. If you have sales reports, compare purchases and revenue for the product over equal periods before and after the change. Note any promotions or changes in visitor numbers that could also explain the results. Customer questions, order corrections, and return reasons can help you check whether the same misunderstanding persists.
