Haley and Hanna Cavinder just revealed what it really takes to build muscle — and it’s not what most people think.
In a candid Instagram post this week, the twin TikTok stars and former University of Miami basketball players shared stunning side-by-side transformation photos showing their physical changes over six months.
Their secret? Eating more, not less.
The revelation challenges common fitness myths and offers a refreshing perspective on what real body transformation requires.

From Chasing Skinny to Building Strength
The 25-year-old twins, who became top NIL earners during their college basketball careers, didn’t hold back when discussing their past approach to fitness.
We used to chase skinny. Which meant under eating, over-training, and wondering why nothing ever grew especially our glutes.
For years, they believed restriction was the answer. Fewer calories meant better results, or so conventional wisdom suggested.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Reality proved otherwise.
The Starvation Trap
Undereating created a vicious cycle that prevented any meaningful progress.
For years we thought less food = better results. In reality, it just meant stalled progress, low energy, and bodies that couldn’t change.
Their experience mirrors what many fitness enthusiasts face: working harder while seeing minimal results. Low energy becomes the norm. Muscle growth stalls completely.
The body simply can’t build what it doesn’t have fuel to create.
The Transformation Formula That Actually Worked
Everything changed when Haley and Hanna shifted their entire approach to nutrition and training.
Once we started eating enough, following intentional macros, and training with purpose that’s when our bodies actually changed.
Three key elements made the difference:
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
- Adequate calorie intake: Providing enough energy for muscle growth and recovery
- Intentional macronutrient tracking: Ensuring proper protein, carbohydrate, and fat ratios
- Purpose-driven training: Strategic workouts designed for specific goals rather than random exercise
The results speak volumes in their transformation photos.
Fueling Muscle Growth, Not Fighting It
The twins emphasized one crucial truth about body composition changes.
Glute growth doesn’t come from starving yourself. It comes from fueling muscle, recovering properly, and trusting the process.
This approach contradicts decades of “eat less, exercise more” messaging that dominates fitness culture. Building muscle requires adequate protein for tissue repair, sufficient carbohydrates for workout performance, and enough overall calories to support growth.
Recovery becomes equally important as training itself.
From Athletes to Fitness Entrepreneurs
Haley and Hanna aren’t just sharing their transformation for inspiration. They’ve built an entire business around teaching others their methods.
That’s exactly why we built our macro program and the Twogether app to teach you how to eat for your body, not against it.
Their fitness app, Twogether, provides structured guidance on nutrition tracking and workout programming. The platform reflects their philosophy: work with your body’s needs rather than against them.

Building on Athletic Success
The twins already had impressive credentials before diving into fitness entrepreneurship.
In 2023, they helped the University of Miami Hurricanes reach their first Elite Eight in program history. Their March Madness run only ended against eventual champion LSU.
As Division I guards, they also became top NIL (Name, Image, Likeness) earners while still in college.
Passion Beyond Basketball
Health and fitness clearly extend beyond professional obligations for the Cavinder twins.
They walked the runway at the Sports Illustrated Swimsuit show during Miami Swim Week in June 2024, showcasing their confidence and physique transformation.
Haley, who got engaged to Dallas Cowboys tight end Jake Ferguson last April, recently shared she’s doing a “bridal bootcamp” to prepare for their wedding day.

The continued focus on intentional training and proper nutrition demonstrates their commitment goes beyond social media posts.
Key Takeaways for Body Transformation
The Cavinder twins’ journey offers several evidence-based lessons:
- Undereating sabotages muscle growth: Insufficient calories prevent your body from building new tissue
- Strategic nutrition beats restriction: Tracking macronutrients ensures you’re eating the right amounts of protein, carbs, and fats
- Intentional training produces results: Random workouts can’t compete with purpose-driven programming
- Recovery matters as much as exercise: Muscles grow during rest periods, not during workouts themselves
- Patience is essential: Real transformation took them six months of consistent effort
Their transformation reinforces what sports science has shown for decades: you can’t starve your way to a strong, muscular physique. Building requires fuel, not deprivation.
For anyone frustrated with stalled progress despite strict dieting and endless cardio, the Cavinder twins’ message is clear: maybe it’s time to start eating more, not less.
