Absolutely an amazing place. My wife and I have tried out multiple avenues of fitness and discipline for our special needs son who is 9 and for some reason he connects very well with Coach Phils program here. This is an amazing place and very clean. The other students are so unique and welcoming. Coach Phil is such a genuine person!

This review is long overdue. My son and a few of his buddies celebrated his 12th birthday at this cool place recently! Coach Phil and his wife were very accommodating, especially since it was a last minute request. Every child had a blast, especially my son. It was a memorable time and Im so thankful to have had the chance to bring my boy here. It was a great experience for everyone! We look forward to going back.

My son has been coming here for the past few months and WOW - we have been so impressed with what the gym offers as well as how Coach Phil works with the kids. They’re not only providing a space and a program for kids to work towards a goal with their physical fitness, but are also instilling amazing core values into them that will carry into adulthood. I have seen my son’s confidence soar as he reaches milestones at this gym and he never wants to leave when we are there! Thank you Coach Phil and Crystal for all of your hard work and dedication to our community’s youth. ❤️

Coach Phil is incredible with the kids! This is the place to send your kid not just for physical activity, but life lessons as well. Respect, integrity, listening and positive encouragement are just a few of the amazing qualities of Coach Phil and these are what he teaches your child also!!PS. My adult friends love taking classes from him also!!!!

My daughter Grace has been training here for over a year now, going 3 times a week and is always bummed when we cant make it. Shes a shy 9 year old, but Coach Phil knows how to get her out of her comfort zone, get her to challenge herself and accomplish things she never would have thought possible. She has learned the core values of the gym (integrity, perseverance, self control, indomitable spirit) and has integrated it into her daily life. The gym structure is set up much like a martial arts studio with different colored arm bands that the kids test for to reward their progression. Whether you want a good exercise program for your kids or train them to compete on ninja warrior junior or just want them to get out of the house for a little bit, I highly recommend Coach Phil and his gym.

My 11 year old son had his birthday party here. The ninjas and coaches were terrific. We had guests ranging from 7-13 and all really enjoyed themselves. This is the real thing, so to say,so there were a few blisters/rug burns/skinned knees.... as long as you dont mind a little gore I highly recommend this as a birthday destination. The kids really loved kicking the pinata as well as the other challenges.

As a former Chief of Police I recommend all parents to give your child an opportunity train at Phil Gym Stone Cote Ninja. Its pretty cool unlike the TV show American Ninja Warrior juniors. It represents a great structure of core beliefs and Leadership. Phil is also an amazing military veteran who has a lot of leadership skills to offer kids in the community. Thanks for working with my son Nick on his fears and minor setbacks.Bravo!

No customer service at all. We signed up for a year membership and have attempted numerous time to get and update with no return phone call. They even moved without notifying us. We have asked for a refund and now have to go to small claims court to get our money back. I do not recommend this place at all.

Had a birthday party there for my seven years old son, and every kids loved it there. The owner is super knowledgeable about fitness. On top of it, the grown ups had fun too.

My kids had a combined birthday party here this weekend. Their names were displayed at the front entrance and plenty of tables were already setup for food, presents, and guests! Each kid needed a waiver signed and watched a safety video before proceeding. The kids were then free to roam as they pleased! Coach Phil showed them how to do several techniques for the many different obstacles. We ended the night with a Warped Wall challenge of all the kids. Everyone had a blast!! 😄 Thank you!

Super amazed with Phil on his new gym! Such powerful perseverance and a fighting spirit! He has so much compassion for the sport and is such a great ninja brother! Best of luck in your gym and with the ANW Fam!JG

I have been training at Stone Core for almost a year now. I found my way there after having my second spinal surgery as a way to learn how to work around some of my disabilities. And also to gain back some of the functionality that I have lost. It has turned into so much more than I expected. All of the staff there is incredible. The training, the direction, and the motivation that they all provide have all been so fantastic. Everybody that I train with are very supportive. They have all become family to me. I love it so much that I now have one of my granddaughters training there also. She is 8 years old and loves it as much as I do. They are helping her to build her confidence and overcome her fears. And by the way, I am 52 years old.

UPDATE: I previously posted a review with some concerns because I wasnt sure who the owner was or how to get in touch with him. The owner (Phil) called immediately and seemed earnestly concerned and attentive. Based on his heartfelt reassurance that I had experienced an anomaly, his explanation of how he was addressing it, and the fact that my daughter had a great time at his camp, Im changing my rating to 5-stars. Phil really seems to care and be truly committed to a safe and character building experience for the kids there.

I seriously have never seen a gym like this, that not only trains kids physically but also what it teaches them about values by the 5 core attitude system that they teach as well. It’s also great for adults. All the staff is super friendly and super knowledgeable about fitness. They take the time to listen to your individual needs. They offer so many different things from adult classes to classes for the kids and even personal training as well if needed. My son loves this gym! Every time we’re in the area he wants to pay Stone Core a Visit. Coach Phil is really good with the kids and takes the time to train you on the obstacles and make sure your comfortable before doing it on your own. I have done the personal training with Coach Phil myself and he does it with you at your own pace and comfort level. Love everything about this gym to everything they offer, the staff, their values and most of all seeing the kids smile and the fulfillment they get completing the courses. Can’t wait until we can go again!

My grandson has been attending Stone Core for a little over 2 years and it’s been an amazing experience for him. It’s more than ninja training, kids are taught values and teamwork. Coaches are great. My grandson recently competed in his first big competition and came in 23rd out 61 athletes in his age group. I think that’s an amazing achievement and thank Coach Phil, Coach Austin, Coach Brittney & Coach Robbie for all their help.

Stone Core Ninja Fitness is a great gym for all ages. My son, James, who is 10 years old has been training and competing here for years. He recently placed 1st in the U.N.A.A. and is qualified for world finals. Coach Phil has been a great mentor to my son. I highly recommend this place.

I absolutely love this gym. It is the best gym I have ever been to and it is a really great workout. The staff is absolutely amazing and I wouldnt change a single thing about this gym. I encourage not only kids and teenagers but adults too, to try out this gym. This gym is great and has definitely helped me archive my goal of becoming an American Ninja Warrior!

Stone Core is awesome. My son has been training here for about 6 months now. Phil does a really great job with the kids from training to instilling core values that they can transfer to any aspect in life. Would happily recommend this place to anyone.

Recently my 4 year old son attended a camp there a Stone Core Ninja Fitness. I have to say that I am absolutely impressed with the overall structure of how the place operates. The owner and head coach of the place known as coach Phil did an Immaculate job keeping all of the kids from ages 4 to 13 engaged in the matter at hand. Coach Austin who is his assistant also did an amazing job working with the kids. They are both super fun to be around and super knowledgeable on what they do. Above all I completely admire the 5 core attitude system that they apply there. I would strongly encourage parents out there to bring your kids to this Ninja Warrior gym. My son had a blast and absolutely loves it!!! A++++

Most amazing Ninja Warrior experience in the Sacramento area! Always an outstanding time! The coaches are amazing and give of great vibes, teach well, and are always willing to help in any way they can! They are so great with kids! Kids classes are great, they love playing on all the obstacles!

This is a really great spot for kids to build confidence and learn to overcome. Great instruction and pricing. The kids encourage each other and my (somewhat shy) 10 yo son felt comfortable immediately. Definitely check it out!

Phil is so good at what he does. I love tree he way he works with the children.

My son loves this place ! We’ve been coming here for over a year now. He hates to miss a class. Great coaches and very safety conscious. Always new and exciting challenges. Thanks to everyone at Stone Core Ninja!!!!

Stone Core Ninja Fitness is one of the most amazing gyms that I have ever been to. The staff is incredible and the obstacles are awesome and always changing. If you want to challenge yourself and especially if you want to learn how to become an American Ninja Warrior there is no better place in the area!

Coach Phil is amazing with these kids, teaching core values that should be applied in everyday life, instilling positivity and belief in oneself, motivating them and the parents watching to never give up! He takes time to share his life experiences, struggles and success in classes as well as apply them to the obstacles the kids see in front of them to give them the strength to not let the moment defeat them but to get up and keep trying and then acknowledges their accomplishment as they achieve them... so just a gym? Definitely not! Coach Phil, and all his staff sincerely dedicate honest care, time and fun into every individual child and family that walks in the door.Thats NOT all though, thats just the bonus to this amazing and fun obstacle course.. the kids love training on the obstacles, and playing in open gym. The camps are made fun for them and lets not forget to mention the awesome themed Halloween and Christmas partys they have here. So you see, STONE CORE NINJA is so much more than just a gym!

If you havent been here, you must. My kids love it and I want to do it as well. Phil and his staff are awesome

Absolutely a wonderful place! The coaches are authentic and great with the kids. Coach Phil is great with the kids and is a real American Ninja Warrior. My 10 year old daughter cant wait to go back everytime now! I would recommend all parents in Solano County to check out this gym for their kids!

My kiddos (ages 7-14) all love the ninja classes here. My little guy has gained so much strength and confidence in just a few months and has been amazing to watch his transformation. The staff is encouraging and easy to work with.

Wow, what an amazing experience this place has been for my grandson! He has been coming to Stone Core for almost a year now and every class and open gym is never enough for him. The membership lessons that they offer here teach ways of over coming an obstacle in front of you..the coaches are very encouraging and give a lot of positive reinforcement all while providing strength training. The kids work together and cheer on each other as a team and then also compete against each other while working together. The obstacles are always changing keeping the classes challenging and surprising!Summer camp has been a great way to spend the day with both short or extended camps offering different themes for each camp. The kids get a more refined experience learning how to tackle specific obstacles and communicate openly in a group as well as play games and just let loose!I definitely see Stone Core in my grandsons future for many years to come... And who knows, he might just be the next American Ninja Warrior!

Yesterday I took my first attempt at anything like this. Stone core is probably the most fun I’ve ever had doing something with the word “fitness” in it. The staff (and the other students) were all VERY supportive and encouraging, showing equal respect and patience for the pros and the newbies like me. The welcoming and positive environment made it really easy to step up and try all the courses without a sense of others judging your experience or skill (they actually cheer you on! pass or fail) Overall it is a fun, challenging, and full body (feeling that today...😂) workout that builds mind and spirit as much as it does muscle. I wasn’t able to complete many of the obstacles but I’m excited to have goals to train for and practice. Definitely will be spending a lot of time at Stone Core Ninja Fitness. Thanks Phil for bringing this amazing sport to Vacaville- looking forward to the future.

This is an absolutely amazing gym! My kids had the most fun on the obstacles. The coaches are authentic a great with children! I recommend others to tryout this place. American Ninja Warriors!!!

Stone Core Ninja Fitness is absolutely amazing! Our community is blessed to have an American Ninja Warrior gym that caters to both kids and adults. They are the only Ninja Warrior gym on the west coast that has a 15 warped wall and classes for kids ages 4-6yrs old. My 9 year old son has attended Stone Core Ninja Fitness for almost a year now and it is changing his life. He has told me that he is so glad that he went to the gym because he got to meet and work with daily the owner and coach of the gym Phil Jameson. In my sons words Coach Phil is kind and wants other people to accomplish their goals he teaches these kids that nothing is impossible if you just dont give up and to keep trying and to always get back up, but above all he instills 5 core attitudes: Courtesy, Integrity, Perseverance, Self Control, and Indomitable Spirit. Coach Phil doesnt just teach these core attitudes but he lives by them. He has overcome many obsticals in his life that would knock a person down but Phil continues to fight and strive for greatness. Our family is very fortunate to have met Coach Phil and we are very blessed to belong to the Stone Core Ninja family because it truly is a family that encourages and welcomes everyone no matter the skill level or background. So, if you or your child loves American Ninja Warrior I would strongly recommend becoming a part of the Stone Core Ninja Fitness family.

My four-year-old daughter and I checked out Stone Core Ninja Fitness for the first time today. We had a wonderful experience! Very friendly and encouraging environment. We didnt make it out of the parking lot before she asked to go back!

My son had his 9th birthday party here last weekend and it was amazing! We had been looking for a place to have a Ninja Warrior birthday and most venues offered inflatable bounce house-type obstacles. But Stone Core Ninja Fitness is the real deal.Stone Core has a Warped Wall and several other obstacles that are right out of the show. Coach Phil, the owner of the gym, is a contestant on the show, so that was exciting for the kids to meet a real life ninja warrior!Coach Phil and Coach Thomas worked with each child to reach his/her potential on the course. All the kids pushed themselves and achieved things they didnt think they could. Several kids and parents commented that it was the best birthday party theyve ever been to! We would definitely recommend this place for both classes and birthday parties!

Staff helpful and encouraging to all ages. My daughter had a birthday party there, and is looking forward to going back again.

If your looking for a place to have a birthday party with a amazing experience Stone Core Ninja Fitness is the place my 8 year old son loved it and cant wait to go back! The staff was amazing and very friendly we will most definitely be going back

My daughter has been training atstinw core for almost two years. The coaches are like family. They care about the kids and want them to success inside and outside of the gym.

My son did the day camp this past week at Stone Core Ninja and he loved it. He said he will definitely do it again next summer if not before.

I am a local Law Enforcement Officer and as such am VERY specific about what I let my boys participate in. Coach Phil and his core principals are exactly the kind of environment I want my kids in. He clearly communicates these values to his students and shows them how they apply to Ninja Training and Life.This is a safe and encouraging environment where my kids are learning and growing in strength, confidence and character

My 2 kids love this. Theyve progressed dramatically in upper body fitness (a family weekness) and attitude toward outdoor fitness. We play Pokémon Go as a family, but get near anything they see as a ninja warrior obstacle (park, jungle gym, raised curbs), they leave their screens behind. Coaches are awesome and encouraging for what is otherwise a difficult set of skills. I am a business attorney and scout leaders and I can say that this is a unique activity and opportunity for both adults and kids.

Stone Core Ninja Fitness has been the perfect fit for my son. He wants to try all the challenges and feels empowered and encouraged by Coach Phil. We are sincerely happy to be a part of this gym.

Our family has had nothing but positive experiences at Stone Core Ninja Fitness! My son loves the positive environment which provides a healthy balance of challenging obstacles, staff encouragement, and promoting self-confidence. Thanks Stone Core Ninja Fitness!

Love and appreciate the encouragement, and dedication the owner Phil gave my 16 year old son. Phil transformed him from an insecure unathletic intravert to a strong confidant young man. If I could give this gym 10 stars I would!

I absolutely adore this place and the staff here. Every class my family and I look forward to attending. Not only is it great physical exercise for the kids to get out and away from their screens inside the house... but it also helps instill great values and teaches things beyond just physical activities. My 4 year old daughter comes home and applies her core values she learned in class to situations she comes across daily. I hope she continues to use these skills in the future too. In addition, the management and staff are also extremely supportive. Not only do they push the kids to go further than just whats expected they also give them the opportunity during free time to work on the obstacles they either love or hate and overcome them. They teach both discipline and fun. Sure there are some obstacles that look a bit unsteady or tricky.. but the coaches do try them out themselves before placing the kids on it. And when going through obstacles the kids have the coaches full and undivided attention. Besides, if the kids fall there are TONS of mats. falling on a course in gym is probably a lot safer than falling out of a tree in your backyard...Just saying. Any person who has an issue with this business, the staff, or the activities is simply a reflection on the type of person they are... Keep up the great work and team. Our family appreciates it and all the hard work you guys put in. (cause lets admit it, 1-2 kids require ALOT of patience... I dont know how you handle a whole class)

I FINALLY made it out to my very first NINJA TRAINING class at Stone Core Ninja Fitness! I got to learn from a couple of the coolest people in Vacaville: Phil Jamison and Robbie Jimenez. I can definitely say this: It is the MOST fun and effective way that I have EVER gotten exercise in the real world!Things to expect: Your palms WILL hurt, you will (probably) get and pop blisters on your hands, you WILL fall down (on padded surfaces), Everyone will cheer you on (whether you fall or not), and you WILL feel like a badass Ninja :DTo Phil Jamison: Great job putting together such an EPIC and unique place to have fun, build practical muscles, and impress positive codes of honor.To Robbie Jimenez: You have no idea how great it was to see you! Youre one of my favorite people that I hardly ever talk too haha. So awesome to see you thriving in so many ways!Looking forward to many more hilariously ungraceful and rewarding days of Ninja training with you all!Dear Reader: Looking forward to meeting you at the Adult Ninja Classes on Tuesday and Thursday from 5-6pm!

It is dope my kids go there and have a blast i feel safe leaving them there to . Coach: Phil, Austin, and Alex are good people.

My kids love this gym. They have been doing the program and learned so much. Thank you to the staff!!

Amazing staff always friendly and attentive my kids love going here

I have watched Coach Phil on many occassions and there is only one thing to say about SCNF......THIS PLACE IS AWESOME! Teaching young kids to perform physical feats is one thing but teaching them how to overcome inner obstacles is truly a God given talent.Specifically, Coach Phil, is able to take time out from the chain of coaching tasks that consumes his time and will undertake a process of learning each youth member in his program, a process that is more often carried out on the run rather than in quiet seclusion. He is able to help the youth dig below the barriers of their fears or hesitations and refocus on the core values and principals that make the individual character strong. Once he has achieved this the youth in his program see and sense those values and principles and gain a renewed sense of purpose which acts as a springboard for confidence, discipline and strength of spirit.By repeating this process again and again through their workouts or daily lives these youth are able to craft an authentic and strong identity based on who they are and not what someone elses understanding of who they are or should be. In this way, through his coaching and core value influences, they begin to make the transition from being a timid follower to becoming a confident American Ninja Warrior and maybe even tomorrows leaders.

He is a phony saying the he was a SEAL and EOD and a combat vet when he hasnt seen combat a day in his life. He is a low life organism for saying that. Hes lying about military service in order to get more customers. Just know that when you come her youre getting trained by a lying piece of trash. Anyone in the military can point out that he is a fake. I just did.

One of the most authentic ninja warrior gyms ive seen i love being here and love what this program does to change my life!!!

Coach Phil was great with my son who had a wonderful experience.

Wouldn’t trust this guy around your kids. Especially your daughtersDon’t act like you don’t know who I am or what you did when you gave me alcohol at your house that night.
