Grassroots Fitness Project

Fantastic experience: Very friendly staff, has everything you need for basic training, very clean too, reasonable prices.

Fantastic experience: Picked up Post-ACL surgery rehab for my 12 year old. Knowledgeable, professional, and inspirational. Sessions turned into total body conditioning including the knee PT, and he was excited to go every time.

Fantastic experience: I've been attending the Women's Strength class for the past few months, and its been an amazing experience! Heather is extremely knowledgeable and is able to tailor any exercise to your needs. She focuses not just on strength but also mobility, which is so important to prevent injury. Heather's enthusiasm and encouragement gets me to push myself in every class, and I've been able to achieve more than I ever thought was possible in just a few short months. The women in the class are so welcoming and supportive that I felt right at home even after my first class! I'm so glad I found GRFP!

Fantastic experience: I've been a regular at Grassroots here on the Upper West Side for several years and in that time I've gotten in the best shape of my life. The team here really cares about and gets to know everyone that comes in the gym and even made sure people had weights and necessary equipment at home during the pandemic. This support of equipment and virtual class offerings helped me lose 30lbs during the pandemic. I would recommend this gym to anyone in the neighborhood.

Fantastic experience: My friends and I have a personalized training session at Grassroots Fitness Project and absolutely love it. Heather is such an amazing trainer/coach. She’s all about women’s strength. Each session is as challenging as each individual wants it to be. It’s such a collaborative and supportive environment— zero judgement since we all have different fitness goals. It has helped me improve my running speed and endurance, flexibility and remain injury-free.

Fantastic experience: Positive: Communication , Professionalism , Quality I work out at grassroots every week, the staff could not be more attentive and knowledgeable, I’ve seen so many benefits and changes in my daily life! Definitely worth it!!

Fantastic experience: Positive: Professionalism , Quality Heather and Wil have created a family and a community filled with excellent, knowledgeable workouts and support - you’ve gotta check it out!

Fantastic experience: I have been working out with Grassroots for 8 years and wouldn’t train anywhere else. Heather and Wil have created a true community where everyone is supported in their journey to be their strongest, healthiest self. There’s no judgement or pressure, just individual attention and guidance. Whether you’re working out in person or online, the trainers are knowledgeable and tailor sessions and classes to your body’s needs and your fitness goals. And you won’t find better workout partners than your fellow Grassroots-goers who will motivate and cheer you on. Grsssroots is the best! There is no place like it and no place better.

Fantastic experience: Having lived in NYC for 28 years, I've tried every fitness class and every new fitness pop up! However, Grassroots Fitness, owned by husband and wife duo Will and Heather, is the one work out place that truly feels like a second family. Once you walk through the door at GF, you are immediately greeted and welcomed into the space. I first started GF as a client taking privates with Heather. Her attention to detail with her thorough entry evaluation was impressive. I'm not as young and spry as I used to be so we talked about areas that needed strengthening and how were were going to achieve realistic goals. I found her to have a nice mixture of thoughtfulness, with carefulness and challenge. Then I moved over to the Women's Strength classes which are small, group classes (women-only) where we deep dive with mobility, strengthening as well as toning. Women working out together immediately create a natural, supportive bond and the dynamics of each group (no matter the age) I found to be very helpful to gaining confidence to try new exercises that once scared me (lifting heavy weights/doing back squats/bench pressing). I'm also a huge fan of the Core & Restore class that aims to build core strength while also teaching restorative breathing and stretching moves. Because this gym is family run, you get that extra attention that, quite honestly, I found lacking at other gyms. Heather and Will go above and beyond to connect with their clients on a personal as well as physical level. They take great pride in their clientele and that shows.

Fantastic experience: Spent good time with Chris. He is excellent and I felt my time with him was always well spent. Thanks!

Fantastic experience: Positive: Communication , Professionalism , Quality After two years working out at this studio, I can only highly recommend it. The rigorous and thoughtfully-planned workouts are fun and yet push me and the place is welcoming with a strong sense of community. As a woman who had never worked on strength training with weights previously, I have found it invaluable.

Fantastic experience: Positive: Professionalism , Quality Grassroots is a bastion of wellness, positivity, and support in a crystal clean gym. Wil, Heather and the team are relentless in their commitment to customize a fitness program that works for you. The best part is the positive vibe, sense of community and passion you feel every time you walk into GRFP.

Fantastic experience: Wil and Heather at GRFP are wonderful . . . I have been working out at GRFP for over 4 years now on a private basis . . . the team of trainers are friendly, enthusiastic, attentive and safety-minded . . . they customize the workout programs to meet your needs and personal fitness goals . . . I have gained strength and stamina and have hit my goals for weight management also - highly recommend GRFP !

Fantastic experience: Grassroots Fitness Project is AMAZING!!! Personalized for all levels in every class (they offer options and you decide which is best for you). Perfect combination of kind, supportive and encouraging. Their small class size, expert attention to alignment, and fun atmosphere is why I have been working out with Grassroots Fitness Project for 15 years. And I have never been more grateful than in the last couple of years. Heather, Wil and their team saved me during this pandemic. If you're curious - TRY OUT A CLASS TODAY!

Fantastic experience: I’ve been a Grassroots client for 4+ years. This is a GREAT, family-run, local gym that genuinely cares about its clients and staff. If you’re looking for a boutique workout experience with terrific trainers, a cool community of like-minded members, and a clean, comfortable facility, Grassroots could be your happy place. I’m a former athlete in half-decent shape who loves to train, but Grassroots caters to and embraces all types, ages, and fitness levels. Some of my favorite people to see and interact with are the seniors who have been long-time regulars. Their space is clean, well-outfitted with gear for just about any training routine, and convenient (close to transportation, easy to access). Wil and Heather (the owners) are warm, real, and incredibly knowledgeable. They are disarming and immediately helped overcome any fear or intimidation I felt walking into a new gym. When I showed up, I was focused on strength. But Will quickly recognized that what I really needed was improved flexibility and mobility in order to build a foundation to get stronger. We have adjusted my workouts as I’ve gotten older to avoid injury and ensure my priorities and goals are always being considered. This is not a cookie cutter, one size fits all approach. The trainers at Grassroots LISTEN, and they build customs programs based on your needs. I haven’t taken a group fitness class at GRFP, but I have watched 100s of them. They are challenging, but the members work out like they are all in it together. Will and Heather have created a real community of motivated, connected people at Grassroots. It’s a special place created by special people, and while I know the purpose of this review is to help attract new customers, secretly, I hope that I can keep this gem of a training facility to myself.

Fantastic experience: I have been working out at Grassroots on the Upper West Side for the past few years and I believe the Grassroots team is the best in the business. Heather and Will (owners) and their team are incredibly knowledgable and their classes and programs are always well thought out. The classes focus on functional movement, mobility and strength with benefits that carry over beyond the gym into real life. Heather and Will know each and every client who walks in the door and there is a great sense of community at the gym. I highly recommend Grassroots for those seeking a top-notch fitness experience.

Fantastic experience: Absolutely love this gym ! They have managed remote classes so well and offered many alternatives during the pandemic :)

Fantastic experience: I have been working out at Grassroots for a number of years. I find Heather to have the perfect balance of being able to push me while also being supportive. The individualized attention and programming cannot be beat. This is not a cookie cutter predetermined workout. This is tailored to where you are at on any given day. Their ability to pivot to a virtual platform during the pandemic kept me working out and fit even during lockdown! I’m so grateful for all that Heather and Wil provide for me, physically and emotionally.

Fantastic experience: I love going to classes at Grassroots! Heather, Wil and the rest of the staff are terrific instructors who always focus on the individual client’s needs. Because group classes are small, I always get individual feedback. I have learned how best to do specific exercises and to build strength- a feature that I rarely experience in large group classes. I find the classes challenging but am never in the position of feeling pressured to do a skill I am not comfortable with- they are very knowledgeable in adjusting to each participant’s level. They are always encouraging, and in their years of building Grassroots, they have created a community of clients who truly care about and encourage other- an important aspect to get me moving and stay motivated!

Fantastic experience: I love GRFP! All the trainers are so welcoming and knowledgeable, and they truly care about every client. In my past few years with them I've gained strength and confidence in my movements, all while being surrounded by the very best community of people who continue to support and encourage each other every single day. Would give 10 stars if I could!

Fantastic experience: I have been going to Grassroots for over 5 years. It is the single best decision regarding fitness that I made. I have belonged to other gyms, but this is the first that has made a difference. Heather and Wil are knowledgeable in what works for you and supportive of an individual's goals. Our entire family have seen benefits in our personal health and goals. My sisters have now even joined (and they live in another state!). My son started here while in middle school to increase his strength to support his rock climbing, my husband for flexibility to support his golf game, and me to bring back my health, strength and well-being! I would not hesitate to recommend this gym to anyone, whether 10 years, 30 years, 50 years or 70 years.

Fantastic experience: Wil and Heather Gunn-Rivera have a great thing going on at GFP. Working out at Grassroots Fitness project has become part of my regular weekly routine,. The personalized one on one training with Wil is fantastic - he is so knowledgable about all aspects of training and knows how to work around injuries that occur from time to time., There are terrific small group classes too - definitely check them out. The energy and vibe of the place is great.

Fantastic experience: Grassroots is a neighborhood gem! I'm so glad I said goodbye to Equinox and found Heather and Wil. They are incredibly knowledgeable and passionate, and two of the most genuine people I know. I started training with Heather just about a year ago when I found out I was pregnant–strength training is such a big part of my life and finding someone who could support me on this journey was extremely important. Heather radiates positivity and keeps me motivated each week. She’s also laser focused on form which I appreciate. I look forward to working out at Grassroots for years to come!

Fantastic experience: Having the option to have remote classes has been perfect!! The trainers are so professional and hard working, their strength class has been amazing!

Fantastic experience: Positive: Professionalism I have been working with Heather and Wil and their team for over 18 years. They are creative, motivating and professional. The personal focus on my particular needs, challenges and goals is exceptional.

Fantastic experience: Grassroots is a family owned business that has been an invaluable asset to our family and we love that it is right in our neighborhood. My daughter takes the girls strength and parkour classes and loves them! I take Women’s Strength and Strength and Conditioning. These are small group exercise classes where you get individualized attention to make sure you are not only getting the best out of your workout but also that you are doing things correctly so you don’t injure yourself. My son used to receive occupational and physical therapy at school because he was delayed in fine motor skills and strength develop (weak core). We decided to supplement that with Grassroots training. He has since graduated from the OT and PT he received at school but most importantly his strength training has given him a lot of confidence that he didn’t have prior. Thank you Grassroots!

Fantastic experience: Positive: Communication , Professionalism , Quality Amazing gym! Instructors are so nice and supportive!

Fantastic experience: Positive: Communication , Professionalism , Quality my boys love working out with Chris, He is a source of motivation for them and I am happy with the quality and service. They do a good job of keeping the kids focused and tire them out.

Fantastic experience: This is the best gym in the world! My family and I have been going to Heather and Wil for over 16 years. Our son and daughter started working out with them at ages 5 and 7. It is a truly personal experience and they have become like family to us. The workouts change every week and are never stale. Heather and Wil cover everything from getting in shape to helping recover from an injury. They really care about their clients and also are very active in the community. They are always encouraging and we have all seen a huge improvement in our health and fitness which I completely attribute to them! We love them!!

Fantastic experience: Positive: Communication , Professionalism , Quality Wonderful, family run business. Extremely knowledgeable trainers, attentive to individual abilities, needs, safety and aspirations.

Fantastic experience: Having been an employee for almost three years, I have thoroughly enjoyed every aspect: the owners (shoutout to Wil and Heather for being genuinely awesome), the trainers who I have seen first hand their incredible dedication to their clients, and the clients themselves who have been a joy to interact with. I love this community so much, and even though I have been working remotely, I still feel a part of the GRFP family! Also as a side-note: I have taken all classes and while in-person is a great experience that I miss immensely, I have truly never sweat so much in my living room while taking a class remotely. I highly recommend any and all services at Grassroots despite any biases I may have. :)

Fantastic experience: Positive: Communication , Professionalism , Quality Wil and heather are the best!! I always love coming to the classes, everyone is so friendly and nice. The classes push you to your limits in the best way possible. If you like HITT classes instructed by motivational instructors, check out grassroots!!

Fantastic experience: Grassroots has made a huge impact in my life. They started by working with my young son and helped him to develop a fitness and heath routine that has shaped his entry into the adult world. For that I will always be grateful. Now that baton has been passed to my wife & I who both have sessions weekly with Wil & Heather. They are helping us better prepare for the later adult stages of our lives. We could not be in better hands. Wil & Heather are a dynamic pair that continue to attract an incredible team of talented associates. Their knowledge, compassion and endless energy makes any investment with Grassroots deliver a high return. I highly recommend GFP for your children, your family and yourself.

Fantastic experience: Wil, Heather and the Grassroots team are the BEST!!! I've been working out with Wil for many years and he has such incredible devotion to my health and well being. He puts together a specific workout for me and my specific goals. And he does it all with such wam, passionate energy! He has been such a blessing in my life! Red

Fantastic experience: Positive: Communication , Professionalism , Quality Wow! I went to this gym for the first time and my mind was absolutely blown! This gym was so sanitary and communicated so well with me! It was so safe for COVID with the social distancing and mask policy. Loved it! Cant wait to come back and achieve more of my goals!

Fantastic experience: I was introduced to Grassroots by a close friend. The Grassroots team welcomed me and taught me how to work out and gain confidence and strength. They continue to challenge me whether it is in person or virtual. It has been at least 7 or 8 years.

Fantastic experience: Positive: Professionalism , Quality Grassroots has been terrific. They provide a thorough assessment to identify what I need and customize the workout to fit my needs. They encourage me to push myself. I always feel better after a season with one of their trainers.

Fantastic experience: Positive: Communication , Professionalism My experience with them has been great!! Such an awesome team of coaches and covid protocol monitoring.

Fantastic experience: Positive: Communication , Professionalism , Quality

Fantastic experience: While I had always loved being physically active, I found myself after two kids, working full time that it was difficult to take the time to take care of myself. On the recommendation of a friend, I was connected to Wil and Heather at Grassroots Fitness. Their approach to fitness is wellness. Wellness of the mind, the body and the spirit. Never judgmental, always supportive they encouraged and supported me. Grassroots Fitness is a family, one that I feel lucky to be a part of.

Fantastic experience: Well-crafted classes with instructors that individuate. Lucky to be a member!

Fantastic experience: Positive: Professionalism , Quality Tremendous trainers there - solid equipment and it's clean

Fantastic experience: I've been loyal to Grassroots since 2013, and I have been hooked ever since. I was never super into fitness, and Grassroots has managed to make fitness a priority in my life and I've been consistently working out with them for many years. Their virtual programs during COVID were amazing, and I was even able to work out more than I did pre-COVID! Heather and Wil are genuinely interested in all their clients and really get to you know you on a personal level. All the trainers they hire are of the best quality in the industry. There is a focus on safely working out and no corners are cut. They listen to you and help you reach your goals. This is an amazing community and I am so happy to be a part of it!

Fantastic experience: Positive: Communication , Professionalism , Quality I have been participating in this gym with ClassPass prior to the pandemic and now do personal training with them. Best experience and best work out

Fantastic experience: I first tried Grassroots 3 years ago because I lived across the street and now it's part of my weekly routine. No matter what my day throws at me, I always leave class with a smile (and completely wiped!). The Grassroots team has allowed me to find my personal strength and see my potential with their never-ending encouragement and meticulous training. I highly recommend giving Grassroots a try and they'll quickly become your favorite neighborhood fitness family!

Fantastic experience: Grassroots is a huge asset to the community and has it all over the other chain gyms. Wil and Heather practice what they preach and instantly make you feel welcome and at ease, and heroic for working out. This was a huge plus for me as someone with a pre-conceived notion of how gyms might be. The facility is clean and they offer many different types of classes for children and adults. The best part of all, however, might be the trainers and clientele that are attracted to this welcoming atmosphere and add to it. I’ve noticed that I’ve become more confident physically and mentally since training here, and I can’t say that about any other gym I’ve been to. You can’t replicate the atmosphere here. It’s a winner. You just have to experience it for yourself and I hope that you do.

Fantastic experience: Positive: Communication , Professionalism , Quality I have been training with Heather and Wil for over 20 years and at Grassroots since it opened. I could not recommend them more! The care, knowledge, and enthusiasm they bring to all they do at Grassroots is exceptional. They have created and continue to nurture an amazing and supportive member community that I love being a part of.

Fantastic experience: It is rare to find a service business that is this exceptional, knowledgeable, focused and dedicated to helping you achieve your best: There with you in the good times and bad (overcome injuries, illness, challenges in life). Grassroots will be your community, rock in the storm, a place you can rely on to bring out the best in you. I appreciate their innovative women's groups, both in person and remote coaching, kids and teen programs for the quality that they deliver; They are as good as it gets anywhere in New York. My journey with them has always been filled with experiences that are fun, exciting, challenging, and inspiring. If you are looking to improve your life, you could not find a better group, facility, community to do it with, anywhere.

Fantastic experience: Amazing instructors who care about form and progress, and call you by your first name. Small group classes (5-9 per) which make the experience truly personalized.

Fantastic experience: Been working out with Heather and Wil every week for 10 years. Each week has been a new and different personalized physical and mental growth experience. Highly recommended.
