Natalia's Prime Fitness helps people across Staten Island, Brooklyn, and New Jersey build the kind of strength you don't lose when life gets loud. One client, one hour, one honest hour of work.
I'm Natalia Alsdorf — an ISSA Certified Personal Trainer, Nutrition Coach, Certified Glute Specialist, and Strength & Conditioning Specialist. I'm passionate about helping women reach their fitness goals in a supportive, judgment-free environment.
Stepping into a gym can feel intimidating, especially if you're new to fitness or shy about working out around others. That's why every program is personalized — built to help you feel comfortable, confident, and successful at every step.
Whether your goal is weight loss, building strength, improving your health, growing your confidence, or simply feeling better in your own body, I'm here to support and guide you on your journey.
Private, programmed sessions in your home, outdoors, or online. Strength, conditioning, and technique built around your history and goals.
Personalized nutrition guidance to support your goals, lifestyle, and cultural preferences — without crash diets or rigid rules.
Targeted lower-body programming focused on glute strength, shape, and function using evidence-based techniques.
Build athletic strength, power, and resilience with sessions designed for performance and long-term durability.
Combine movement coaching with nutrition strategy in one session for clients who want integrated results.
For clients outside my local area or who prefer to train from home. Real-time coaching and feedback over Zoom.
Train with friends, family, or coworkers. Same programming quality, shared energy, and built-in accountability.
Commit to your progress and save. Packages apply to one-hour personal training sessions.
Movement, history, and honest conversation. We map where you actually are.
A plan built for your calendar, not a template someone else outgrew.
Sessions that push and protect. You leave tired, not broken.
We review every four weeks. What works stays, what doesn't goes.
A glimpse of what targeted lower-body work looks like — controlled movement, proper form, and programming built around real results.
I came in scared of the barbell and left feeling like an athlete again. Natalia made the hard part feel possible.
The first trainer who actually listened. My back pain is gone and I'm stronger than I was in my twenties.
She rebuilt me after my second pregnancy — patient, precise, and never once made me feel behind.
As a busy mom, I needed someone who understood my schedule and my culture. Natalia checks every box.
I never thought I could enjoy strength training. Now I look forward to every session — even the early ones.
Her remote program kept me consistent while I traveled for work. The weekly check-ins made all the difference.
A 45-minute consult and movement screen — no pressure, no pitch. If we're a fit, we'll book you in. If we're not, I'll point you somewhere that is.
