About me
I am a young, motivated, and highly skilled personal trainer that has devoted her passion for sports and helping others into a career I have been building for over six years. I believe my experience aligns well with the qualifications you are seeking and we can make a great team! I’ve helped athletes reach their performance goals, I’ve helped elderly clients recover from injury or limited range of motion, and everything in between. My training philosophy is all about making fitness fun and moving without limitations.
Before I became a certified personal trainer, I was never too shy to shadow trainers, coaches, and doctors. As I pursued a B.S. in Exercise Science, I had various intensive internships under physical therapists, and athletic trainers while I passionately studied the art of movement. I grew up in Manhattan playing various sports, cycling, exploring the glimpses of nature the city has to offer, and finding new ways to stay active. I am currently studying for my CSCS, and applying to Masters Programs in related fields. Moreover, my on-the-job experiences have afforded me a well-rounded skill set in in being able to create fun, efficient, and progressive training programs for athletes, weekend warriors, youth, elderly, and special populations. I am adept in individual and group instruction, expert programming, and fitness assessments in a friendly and professional environment.

Fantastic trainer, delivers tangible results!There are a few things I look for when searching for a personal trainer. They have to understand and appreciate the uniqueness of my goals, must understand my lifestyle and habits, have a good suite of knowledge on form and fitness, and must be a good time. Nathalie is really great at all of these. Essentially, I use her as my encyclopedia on all things fitness and nutrition. I would highly recommend Nathalie for clients who are looking to learn more about themselves and learn more about how to incorporate a healthy lifestyle into their current lives. Nathalie is flexible and lighthearted and kind. We have been training for several months now and I am surprised with how much she has impacted my life. She doesn't try to reinvent the wheel- she uses sound exercises that targets specific muscles, heart rate zones, etc. Nathalie is a true motivator and has the ability to dedicate our session time to rejuvenate my mind and body. She is an excellent listener and can understand my commute, lifestyle habits etc. so she has tailored her training and coaching to fit my life. For example, she's given me coaching on how to eat based on when I wake up (4:45am) to when I go to bed (12am); and has helped me fit in workouts into my schedule in ways where I may have not seen opportunity to maximize that time. I trust my trainer's expertise and now also trains my son who has autism. Justin loves working with her! It goes without saying that one of my Nathalie’s strengths is being able to see weaknesses and learn more about a client’s body's strengths/weaknesses through the workouts. She's constantly observing to see where my imbalances are, where I'm stronger, and what forms I need to work on. Although it may see cliché, I hold this statement to be true about Nathalie: “Nathalie is a fantastic trainer, delivers tangible results, and has the ability to change a life. - Sam S
A cut above the rest...Like many, I decided to start my fitness journey in January. I was not too fond of the idea of having to restart at a new high end health club. I've done it in the past, and quite frankly, the setting was too intense for a beginner like me. After months of searching, I came across In-Home personal training. Something that sounded appealing yet terrifying because all the little voices in my head that I've used as excuses, has now vanished- poof! Here comes this trainer at my door with a Mary Poppins duffle bag (full of resistance bands, foam rollers, TRX bands, boxing gloves, and more) and a huge smile. Nathalie was very intuitive and knew how to ask the right questions to understand my goals better. With our initial assessment, she was able to determine imbalances I did not know I had. I sit in an office all day for work and did not get in enough mobility. She explained to me the importance of engaging my superficial backline and scapular stability. Before I knew it, I simply wanted to look good in a bathing suit. But Nathalie taught me how to move, she expressed interest in my journey, making sure I ate for my goals, and slept well at night. My experience with Nathalie is well rounded. She taught me how to live a healthier life and feel better because of it. I was such an eager student that I did not realize how much improvement I was making. Fast forward a year later, I've lost 40 lbs, no longer high risk, I've been healthier than I've been since my college years without having to step foot in a gym, and I feel great! Nathalie has been nothing shy of exceptional. She’s a cut above the rest and truly cares about your progress. Nathalie is one to keep things fun, educational and keeps me revolving from cocoon to a butterfly. I highly recommend training with Nathalie if you get the chance, for any fitness and wellness goals you may have! - Roseanne H
Enjoying my experienceI'm enjoying my experience with Nathalie as my fitness coach because she knows just how to challenge me. Not too hard to discourage me and hard enough to make sure I reach my daily goals. With my busy schedule, New York lifestyle, and ambitious fitness goals, Nathalie is accommodating and helped me compete in my first IronMan triathlon. I've done smaller races in the past without formal training and I thought I knew it all. Nathalie has been better than any fitness app or any predesigned program. Each one of our sessions, whether we're indoors or not, was specific to my capabilities, goals, and measurements. A true leader, my coach knows how to encourage and empower from within. She’s over 30 years younger than I am, and I’ve been involved with fitness for decades, but Nathalie definitely schooled me and took me to a new level of beast. - Benito C
Awesome trainer!My trainer and I had a running joke- I hated fitness but I only enjoy it with Nathalie. I was never one to enjoy working out in the past, literally I hated it. Josh and Nathalie, the owners of Bodies In Action, are AWESOME trainers. They have all sorts of great programs, for brides and moms to be. They gave me a great fitness routine while I was pregnant. With their training, as well as yoga practice, I stayed very healthy during my pregnancy and was back in my regular clothes within three weeks of giving birth. The other great thing about them is they mix it up - you never get bored working out! Over these past months of training with Bodies In Action trainers, Nathalie has completely changed my outlook on exercise. The best part of my day is going to work out with her. They're super personable and knowledgeable beyond belief. They're driven, and I can see the passion in how they interact with clients seeking answers. BIA trainers believe in the science of movement but break it down so that it is much more than movement. With my trainer at Bodies In Action, I feel revitalized and fitness has now become my sanctuary. - Joanna K
Outstanding and smart!One word I would use to describe the trainers at Bodies In Action is Uplifting. The trainers are all masters of their craft and have the ability to push you physically yet care so passionately about your well-being and vitality. My trainer is Nathalie. She has become a very important figure in my day to day life. Starting off, she is very professional, all-encompassing, and never late! This says a lot about one’s character. She’s very comforting and doesn’t just take you through the movements and counts the reps. Her thoughtfulness seeps through when she sends you an article she mentioned she would during the session, or when she brings you a piece of fruit when you mention how exhausted you are and not feeling too well. Her analogies are always funny and relatable too! All in all, Nathalie is outstanding and smart and I highly recommend Nathalie and Bodies In Action. - Victoria J
Now in the best shape of my life!Nathalie’s Bodies In Action concept of one on one personal training is well executed. Your personal trainer identifies a training program based on your needs and wants as you have identified them both at the start of the program and as it goes on. Their trainers are knowledgeable and skilled. My Bodies In Action trainer, Nathalie, is hands down the best trainer I've worked with in the past 10 years! I've had my share of trainers and I'd have to say my experience with Nahalie has been phenomenal! Her first priority is luxury customer service. From her timely responses, to working around the clock to accommodate my busy schedule, Nat is top-notch. My trainer was really genuine, helpful, and professional. With her impressive educational resume, and her dedication to her craft, she implemented a program that has gotten me in the best shape of my life. I have lumbar stenosis. Nathalie developed a program for me so that now I am barely aware I have it. My doctor sent me to physical therapy to strengthen my balance and core. Nathalie works with me to continue the exercises my physical therapist prescribed in a very scientific and integrated manner. - Michael D
Absolutely a worthwhile investment!I came to Nathalie with one goal in mind. I wanted to play Division 1 soccer for my dream school. I’ve played soccer since I was five years old and have traveled through the states in some very important tournament and showcases. My current high school is also known for having a great Girls’ Varsity program. It is safe to say, I have experienced my fair share of soccer- Many coaches, many athletic trainers, and even many physical therapists. I’ve torn my ACL in the past (twice in the same knee), torn meniscus, broken collarbone, and a few lower back complications. Before entering my junior year of high school (my intended breakout year), I decided to seek a personal trainer to learn about overall fitness, not only my soccer skills. I wanted to get stronger, lift more, move better, and ultimately perform better. I was connected through my mom, who has been raving about Nathalie for months now. My mom seemed happier, and more excited about working out so I assumed Nathalie must be some kind of mythical creature to get my mom to enjoy fitness. Once I met Nathalie, I was thrilled to discover she is an athlete as well and has experience with multiple sports. Her knowledge stood out to me, she was able to teach me a few new things about movement within just minutes of meeting her and I thought ‘wow, I’ve been doing this my whole life and I’ve never approached it that way’. She coached me through movement I thought I couldn’t even do, until at the end of each set she’d say ‘See, I told you you can do it ’. Nathalie was like a big sister because she knows when to make jokes, yet respected enough to make me do those last few reps or sprints. Nathalie's passion is to unlock the potential of the adolescent athlete, like me. Sometimes that potential, either mental, physical, or both, is hidden from the athlete. Nat has a deftness for connecting with the athlete and identifying the path to success. The great thing about her is that she is not a sports specific trainer; she can work with any athlete, in any sport, and help that athlete to achieve their full potential. Her workouts are challenging, fun and absolutely individualized. They are mentally and physically engaging. And she gets results. I have full faith in Nathalie’s abilities, because I have seen her work her "magic" with me (and my mom). I have a new confidence in my soccer skills because of Nathalie and we never even touched a soccer ball while training together. She has made me tougher and more disciplined on and off the field. Take this from a sixteen your old, working with Nathalie is absolutely one of the most worthwhile investments you can make in your child's life. - Madison J
