Working with Jennifer at J.E.T. Fitness has been a wonderful experience. She’s incredibly knowledgeable about the body, macros, general mindset and everything in between. She makes herself available for questions and is really encouraging in her videos. I highly recommend working with her!

Working with Jennifer at Jet Fitness has been an absolutely transformative experience! From the very beginning, the onboarding process was seamless and straightforward—everything was set up to make getting started as easy as possible. Jennifer’s training plans are incredible. She took the time to fully understand my goals, lifestyle, and fitness indicators, and then tailored a plan that fit me perfectly. Her approach is so personalized that it felt like I had a program designed exclusively for me—not just a one-size-fits-all template. What sets Jennifer apart is her support throughout the journey. She regularly checks in to track my progress, listens to my feedback, and makes adjustments to the plan whenever needed. It’s clear that she’s as invested in my success as I am! The results speak for themselves: I’ve lost 35 pounds in just 4 months, and I couldn’t be happier. I feel stronger, healthier, and more confident than ever. If you’re looking for a program that’s not only effective but also backed by someone as dedicated and encouraging as Jennifer, Jet Fitness is the place to go. Highly recommend! Thank you, Jennifer, for helping me achieve what felt impossible just a few months ago!

I have been working with David since January and it has been amazing. He is always very supportive, encouraging and positive. This is definitely a lifestyle change and a journey. My daughter gave me the fitness and nutrition package as a Christmas gift and it was so appreciated. Although I do not live in New York it proves this can be done at a distance. Shout out to David for all his patience and positivity!

Working with Jennifer has changed my experience with fitness and nutrition coaches. For the first time, I have felt like I can enjoy my life and not have to skip out on things to perfectly hit my diet. She is also just an amazing person and is always there to lift you up or listen!Dana N.

Life changing experience. Aside from my new healthy routines, I feel like I have a real coach and cheerleader in David. Food and workout plans are totally reasonable and I feel better! Thank you thank you!!

LIFE CHANGER!!! Literally! I've been working with Jennifer for almost 4 years now, and I can't believe all the changes both physically and mentally. I don't even recognize myself! Jennifer has guided and supported me the entire way, and it's such an honor to work with someone so kind and knowledgeable. I wouldn't be the person I am today without her. She deserves more than the 5 stars they allow!

What are you waiting for!! J.E.T. Fitness has been a game changer for my fitness routine. David, my coach, has been amazing. He took the time to understand my fitness goals and crafted a workout plan that perfectly fits my needs. His expertise and encouragement have made a huge difference, and I really appreciate that he’s available to answer any questions. If you’re looking for personalized support and a great community, this is the place to be!

Jennifer is the most unbelievably knowledgeable, supportive, and motivating trainer. I feel better than I have in years in just a few short months. I was intimidated to get back to working out etc, but truly Jennifer has made it a joy and met me with compassion, encouragement, understanding and real-life support the whole way.

Working with David at J.E.T. fitness has given me the accountability and direction I needed, and I have now been consistently working out at the gym for the first time in my life for almost six months! I feel stronger and more capable than I ever have, and David is fantastic at communicating and at creating exercise routines to help me reach my specific goals. Thanks yall!!Description goes here

I’ve been training with Jennifer for 4 years now and I’ve never had such a positive experience with a trainer and coach. She understands the pressures of performing while also holding you accountable to your goals. She is the most supportive trainer you could ever ask for and I’m so glad to continue working with her long into the future!

I’ve been with JET Fitness for about one month and I love it. I started off a little rocky but David made sure I was comfortable and if I ever needed support in anything he was there to help. It’s only been a month but I’ve lost weight and feel great.

I cannot recommend J.E.T. Fitness enough! Jennifer has created an individual nutrition plan for me that is getting me to my goals while helping me understand how to find a balance in my life. I feel stronger and better in my body than ever! She is attentive, knowledgeable, realistic, and supportive!

I’m 47 and have been working with David on just the macros, and I cannot believe how much my body is changing for the better! My muscles are popping from the same workouts I’ve been doing for years with little to no results. Turns out I just wasn’t feeding them properly! Thank you JET Fitness!!

I love working with David! Affordable, genuine, and honest. David has given me great advice and support as I am working my way through injury and post-second baby weight / fat loss. He’s been attentive and always responsive. I love the format of the check-ins and the apps used to track! I signed up for 3 months but I will definitely be going longer! He’s patient with me as I am working to be just a little better each day!

Jennifer is so invested in every clients training, which makes training with her so easy. She is always available to give tips or help you get the exercises right for the best results. She's so encouraging and flexible, all around, this is the only exercise program I've ever stuck to and genuinely enjoyed!

David is the best!! He helps keep you on tracks and motivates you to be the best you can be, while also working with you and adjusting your workouts depending on your strength. I have a partially torn meniscus and he has adjusted my exercises so I don’t feel pain while also strengthening my muscles to help make the workouts easier. David is the absolute best, I feel more confident and stronger since I started working with him!

I am at the beginning of my journey with coaching with Jen, but I already feel like I have made such a great investment that will pay off! It feels so great to have someone who is there to support and meets you with kindness, encouragement and factual knowledge. Any time I’ve previously tried something like this, I quit fairly quickly and I’m grateful that she is understanding with how real life is and that fitness doesn’t need to be toxic or difficult. I look forward to continue working with her and highly recommend to anyone wanting support with their health journey!

I have been working with Jennifer for a couple of months now and am excited about the results I am seeing! It’s great to hand someone take the confusion out of macros and cheer you on. I love her positive attitude and holistic approach. I was in pretty good shape when we started and was looking for someone to help me take it to the next level. Definitely recommend!

Jennifer is an INCREDIBLE coach with boundless knowledge of the body and the way it wants to move. She is patient, thorough, and generous with her time and help. I have been working out with her for a year and a half and I have learned so much from her and seen both my body transform in the process! I keep learning new things from her. I can’t recommend JET fitness enough!

This year I decided I was gonna invest in my health like I hadn’t before. I knew I was missing something or several things and I couldn’t risk spending any more time trying to figure it out myself. So I partnered up with David at J.E.T. and that 3–6 week period where I would normally hit a wall and be exhausted and miserable ended up being just the start of hitting my stride with David’s training and his guidance on diet. The program allows a lot of freedom in both workouts and diet which breeds a lot of positivity and growth. I’m almost halfway to my goal which I know I’ll achieve. This has been one of the best investments I’ve ever made!

I’ve been working with Jennifer for ten months and I can’t say enough good things about my experience so far. The workouts, feedback and support at truly tailored to me. Jennifer is thoughtful, encouraging and SO GOOD at what she does. She truly cares and it’s evident in every single interaction. Not only is she wonderful and the greatest cheerleader, but the results of the program speak for themself. I cannot recommend her and the JET fitness + nutrition enough. It’s absolutely changed my life.

I have been training with David since September and I feel such a difference! The accountability without judgement and encouragement without negativity are so helpful during my fitness journey. I love working with this team and would highly recommend.

This has truly been one of the best investments I’ve made this year. Committing to a program that demands discipline over an extended period is no small feat. But what’s even harder is finding someone who is as deeply invested in my goals as I am. Jen’s unwavering support, expertise, and dedication have made all the difference in my journey. I’m genuinely grateful to have her in my corner, guiding me every step of the way.

Jennifer if the most encouraging and responsive coach!! Anytime I have any questions or issues she is there and is truly the biggest cheerleader! I highly recommend ✨I feel stronger and even with a few setbacks with injuries I’ve been working through she is THERE for you and can modify for your needs ❤️

I’ve worked with coaches both in person and virtual several times in the past and Jennifer is THE BEST. Extremely helpful and valuable for anyone no matter what your previous level of experience may be. They will meet you at your level and help you to thrive! Signing up with JET is the best decision I made this year.

The coaches are extremely supportive and knowledgeable. I have never felt healthier or been stronger. Life changing, actually.

Jennifer Gellar is an exceptional coach who really takes the time to get to know her clients. She provides encouragement as well as honest and accurate feedback essential to reaching health and fitness goals. Jennifer promotes body - positivity and healthy habits that are sustainable and practical for individual lifestyles. It’s a pleasure to work with her, as her kindness shows through in the support she offers.

I’ve been working with Jen since early Aug doing the precision nutrition plan. I feel incredible, look fantastic and can’t believe how much I’ve learned about changing the way I eat, what I eat and how much I eat. It’s been eye opening! Jen is warm, supportive and super energetic. I’m so grateful and am so excited to keep going on my journey with her!!

I’m new to J.E.T Fitness, but I’m already so impressed! Not only do they know their stuff, but they provide excellent fitness resources to support your goals from afar, and they are wonderful at encouraging you along the way. Highly recommend!

Jennifer believes in me and my ability to change for the better, a healthier version of myself. It’s been an up and down ride with me but she remains consistent in her knowledge, motivation and mindset to help me achieve my healthier version of me. I’m getting there! No food is off limits as long as you fit it into your macros for the day. And as she reminds me, this is temporary. Once I hit my healthy, it will be about maintaining with movement, fueling my body, and consistency. You won’t regret signing up, but you must show up for yourself.

So thankful for JET, jen is the absolute best!!! She’s an inspiration, such a hard worker, so kind & motivating. Keeps you accountable in a kind way and created a beautiful community! Thank you Jen!

David and J.E.T. Fitness have changed my life. They have such a stress-free, no judgment way of helping their clients be stronger versions of themselves. No food shaming, no deprivation. David is always accessible to get help or just give a high five for a completed workout. Highly recommend to anyone who has been struggling to find a routine that works.
