About Me
Welcome! I’m Nissania Hazghia, founder of Fit by Niss, a Pilates and strength training brand rooted in empowerment, wellness, and results. I specialize in helping women feel strong, sculpted, and confident—in every season of life.
As a certified NASM Women’s Fitness Specialist, Pilates instructor, and passionate coach, I’ve created a unique approach that blends classical Pilates technique with functional strength training. My focus? Helping women—especially ages 35–50 and beyond build lean muscle, improve core strength (yes! even with diastasis recti), and feel amazing in their bodies.
I teach one-on-one and small group reformer Pilates classes in Great Neck, NY, where I bring energy, expertise, and personal attention to every session. Whether you’re just starting out or looking to break through a plateau, you’ll get customized, results-driven programming in a supportive environment.​
My Philosophy
-
Science-backed strength: From building bone density to sculpting abs, we train with purpose.
-
Balanced nutrition: High-protein, macro balanced meal strategies are part of the transformation.
-
Consistency over perfection: Progress is personal, and I’m here for the long haul with you.
-
Functional fitness: I design workouts that serve your real life—not just aesthetics.
My Journey
Before launching Fit by Niss, I ran a successful design business for 13 years. That creative eye now translates into thoughtfully structured classes, branded materials and a deep understanding of what it takes to build something meaningful from the ground up.
Who I Work With
-
Women navigating body changes and hormonal shifts
-
New moms rebuilding core strength after pregnancy
-
Fitness beginners looking for a safe, welcoming space
-
Athletes and active adults seeking low-impact, high-result training
-
Anyone who wants to feel energized, toned, and confident
Let's Get FIT - Together!
Whether you’re walking into the studio for the first time or returning to movement after years away, there’s a place for you here. Come jumpboard, stretch, lift, and laugh with me. You’ll leave every class feeling stronger, taller, and more in tune with your body.
Helping women stay active & strong!
I can’t recommend Fit by Niss enough! I was really nervous to get started after not working out for a few years, but Nissania made it so easy to follow at my own pace. Each class helps me build strength and confidence, and I always leave feeling better than when I came in. She’s an amazing instructor—knowledgeable, supportive, and she makes every class fun! I highly recommend giving it a try.
