Ame & Rob

...from Struggle to Strength
Every journey that creates real long-term change begins with a challenge, and for Ame and Rob Greco, that challenge was their own health. A typical working-class couple raising a family, two kids, a dog, a mortgage, car payment, and a visit or two to Wisconsin Dells during the summers... Perfect! Yet, all those years they never realized they had been neglecting their own well-being until they had enough...

At one point, Ame weighed over 260 pounds and Rob over 235 pounds! Both stuck in a cycle of unhealthy habits, unsuccessful fad diets, questionable juice cleanses, and never ending 'bad' health advice from every direction they turned, all of which only led them straight back to weight gain and frustration.

But instead of accepting defeat, they made a choice: to change, to fight, to reclaim their health and gain strength. In 2017, their real, sustainable, fitness journey began—not with quick fixes, but with hard work, sweat, education, and relentless dedication to do it for themselves. Now, with their new sustainable habits, self-accountability and perseverance to change, they shed the weight, built muscle, and transformed not just their bodies, but their lives!

Today, Ame is a NASM-certified trainer, turning her own transformation into a mission—helping others break past their limits, build strength, muscle, shed fat, and develop unshakable confidence in the process. Rob, as Head of Operations & Gains, brings over 15 years of business expertise and firsthand fitness experience to Sabertooth—keeping operations running seamlessly while understanding exactly what it takes to push through challenges in business, training, and life..

Now, through Sabertooth Fitness Company, Ame and Rob share their passion, their lessons, their wins—and even their failures—so that you can succeed in your own journey. Because they’ve been where you are, and they know what it takes to push through and win.

Your story isn’t over... Your transformation starts now. 💪🔥
