About
My name is Stella Mechkova and I'm here for you.
I founded Gostellr because I know what it’s like to feel stuck in your body, lost in your goals, and disconnected from your potential. My story is one of transformation—not just physically, but mentally and emotionally.
At 16, I discovered powerlifting and fell in love with strength. But behind the physical progress was a growing struggle with disordered eating and a mindset rooted in self-criticism. I believed that eating less meant working harder, and it took a toll on my health and self-worth.
In college, I stepped away from strength training altogether. After being diagnosed with PCOS, I experienced rapid weight gain and the lowest mental health I’d ever known. I felt defeated, directionless, and deeply disconnected from who I used to be.
But I refused to let that version of me be the final chapter.
I made the bold decision to graduate from the University of Michigan two years early and committed to rebuilding myself from the inside out. Post-grad, I fell in love with running and Pilates—and while I lost weight, I was still trapped in the belief that restriction was the only way forward. I was under-eating and overthinking, constantly chasing control instead of real freedom.
That changed when I made one empowering decision: to stop shrinking and start building.
I returned to strength training with a new goal—to fuel my body, repair my metabolism, and train with purpose. I’m now preparing for my first NPC bodybuilding competition, eating more than I ever have, and fully stepping into the strongest, most energized version of myself.
Through this journey, I became a NASM-certified personal trainer, nutrition coach, and life coach, because I realized that fitness alone isn’t enough—true transformation starts in your mindset. I'm also currently furthering my education through graduate-level coursework at Harvard, where I’m deepening my ability to help others with evidence-based tools and strategy.
Gostellr is more than a business—it’s my purpose. I created it to be the space I needed when I felt stuck, unsure, and searching for a way forward. It’s a reflection of everything I’ve learned, overcome, and rebuilt—from the inside out. My mission is to give others the support, structure, and strategy they need to feel strong, confident, and in control of their own journey. If I can help even one person realize they’re not broken—they just need a better system—then every step of my story was worth it. This is more than coaching. This is your comeback. And I’m here to walk it with you.
