If superheroes needed boxing lessons, they'd train here. This family-owned gym isn't just teaching kids how to throw a punch--it's teaching discipline, confidence, respect, and how to survive family game night arguments without turning them into a title fight. The owners are some of the most honest and hardworking people you'll ever meet. In a world full of gimmicks, they're the real deal. The coaches somehow manage to keep a room full of energetic kids focused, which honestly deserves its own championship belt. They invest in the youth, support the community, and make every kid feel like they belong. Rumor has it that after a few months here, kids stand taller, work harder, and suddenly start cleaning their rooms. I can't confirm the last one, but the confidence boost is definitely real get it read more

I want to be constructive and credible before allowing myself to give a negative review and not allow my emotions to reflect on my decision but MY REVIEW is NOT based on being bias, but reflection of how my (friend)and myself as customers expectations from a business. This is based on lack of professionalism. And a business that has coaches who are not being a multi-faceted role models and be involved. Coaches not not fully engaged in the indivuals training. I understand that coaches may be overwhelmed with multiple responsibilties training many athletes, managing schedules , or handling commitments. But this place needs improvement with communication, coaches need to be actively involved (NOT JUST PRESENT). Since January this year I referred one of dear friends to this place and pay for the invidiual sessions. Only to be disappointed that the trainers dont create training plans and understand feedback or show motivation and support. We validate by improvement and monitor progress because this is needed as this is a skill development by encouragment and positivity. In this case Coaches need to understand everyones perspectives and be more involved. (NOT ALWAYS ON THE PHONES) I am extremely disappointed and hope this business can be more involved with their customers. I have launched an investigation and a follow-up. read more

Grampa's Boxing Gym is not an average boxing gym. It's a very old-school boxing gym with a great atmosphere. Coach G and the other coaches are all very nice and knowledgeable. They push you hard, but also at your own level, which makes it good for beginners and more experienced fighters. They offer monthly membership where you can take as many classes as you want, but honestly every class is intense -- I was so tired I could barely do more than one session a day. Overall, it's a great place to learn boxing. If you really want to improve, you have to put in the time and effort, and the coaches will start taking you more seriously as you commit. Don't expect to learn cool stuff when you don't have the basics down -- you will eventually learn everything you need to know step by step, but that's why consistency and effort matter the most. read more

I have gone here since i was in 8th grade and just finished my senior year, without this gym and the coaching/staff i wouldn't be the person i am today. they helped me build confidence in my everyday life and taught me to work hard for what i want. Coach Angel wasn't just a coach but also a friend I could rely on, he kept the gym fun and full of new experience. read more

Hands down best boxing gym out there. Looking back, I can honestly say I wouldn't be the person I am today without this gym and without my coach. Coach Angel has not only pushed me as a fighter but as a man. The one to one attention, traditional boxing instruction and genuine care for every fighter is what sets this gym apart. This is definitely the gym to learn REAL boxing. Forever grateful for everything I've learned here Highly recommend read more

I've been going to this gym and getting one on one personal training for almost a year now and I've had the pleasure of working mainly with Jessica as well as Giselle. I've had nothing but good experiences with both of them. All the trainers here are amazing, but these two ladies have gone Above and beyond and catered to what I've been looking for and what I've missed out in training all these years. I'm truly grateful for the level of confidence in these ladies and how much attention they pay to my back issues and change up my routine to minimize any further exacerbations, While still not allowing me to slack off and pushing me to work as hard as I possibly can. I drive 30 to 45 minutes to get to this gym so I know it's worth it. I've never once been bored with the routine as there is something different every single time. Which is what makes me want to continue to come back. I hope to have many more years here. Thank you for getting me back in shape ladies. Everyone is so sincere and polite here. read more

It is a great place for boxing and training in OC. My sons are boxing here likely 3 years and is continuing boxing here. Every coaches here are great, especially, coach Angel who is coaching my sons since the first day. Grampa's is a great place to go for boxing with reasonable fees. read more

I've been here for over a year and a half and have enjoyed every minute of being in the gym. Coach G is always pushing you to be better than what you think you can be. Her availability is so wide that she will always be there to help you improve your abilities. read more

Been going to this gym for a minute now and I can say with confidence it is the best gym I've been to. I can get self conscious about my weight and working out in general but it's always so welcoming and I never feel judged here. All the coaches treat you like family it's truly the best!! read more

She is fun and a great coach! She creates a positive environment and makes everyone feel comfortable while still helping us improve. I always enjoy working with her. I have taken my son with me to train and coach g is amazing at having patience with me as well as my son ! read more

Well let me start off by saying that I am not a staff member writing a review like the previews notes. I am writing a review based on my personal experience and on some members thoughts." This place is very bad, the problem is the owner and coaches, very bad attitude and ego, if you come here be prepared to be hated especially if you're a girl. Coach Gisselle I don't recommend, she only cares about the guys and forces more on them. That's if you're a "fighter" other than that she's usually on her phone or in the front with her madrina (the owner) wasting the class session, time and money. read more

Grampas boxing gym is a great place to learn and meet people. It is ran very well with a bunch of great coaches. I have been training with coach Angel and he has been very great. He has a great understanding of boxing and is also a kind and caring person in general. read more

I been having such an amazing experience at this gym, especially training with Coach G. Since I run my own business, my schedule is very busy, and Coach G is always there for me at 6:00am so I can train before starting my day. That level of dedication and support means a lot. I see myself getting better when it comes to sparring and physically more in shape. Coach G genuinely cares about her athletes and pushes you to become the best version of yourself. Every session is challenging, but I feel amazing after every training session. Even though it's 6 or 7am Coach G always has a positive attitude that really has us pumped for our early morning training. I Highly recommend coach G and Grampas Boxing Gym. read more

This gym is amazing. I've went here for 5 months and the staff have been kind and patient with us. They treat you like family.

I really like this gym, I've been coming to Grampa's for about a year and it has a great welcoming environment. The gym has a vintage classic feel where you know you're going to get work done. All of the coaches and staff are really friendly and experienced to help you with anything from a beginner light training to a more experienced fight preparation. I've been training with Coach G and she's amazing! She's helped me lose a lot of weight. Her classes are very fun which have allowed me to maintain a consistent routine. I can't recommend Grampa's enough, great for beginners and competitive fighters alike read more

Nice gym but the coaches are not good, they're too young and don't take the session seriously, they stop the sessions to talk to other coaches waste of time and money. I don't recommend coach G at all, she doesn't care about you unless u are a fighter competing and never gives feedback. read more

don't recommend coming here this gym is very unprofessional, I was with coach G and she has favoritism she picks and choose who she really wants to give her attention too. always slacking on the phone, waste of money and time!!!! The owner of the gym is her madrina so they won't tell her anything there's better gyms in OC read more

don't recommend coming here this gym is very unprofessional and so unsanitary , coach G is the worst I can possible say , always slacking being on her phone, waste of money and time if you decide to come here !!

Had to leave CA and moved to SC. There's nothing like Grampa's here in The Low Country so I set up a gym in the garage and after finally getting a good base, I fell head first about 9 1/2 feet breaking a bone in my back. That was late April and now it's mid July and I just started training again. More than the SoCal weather I miss the people at Grandpa's. Hope y'all are doing well. read more

I used to love this place! It had a great community and felt like everyone was family. If you had kids and were struggling they'd often give you extra time and they have a lot of community events. Ever since Jessica took over that has gone, it's gotten so commercial and all about making money now, it's sad. Her family really loved taking care of people and the community sad to see those values going over a quick buck. Prices have gone up exponentially for memberships and coaches, and if you aren't competing they don't really care too much about you. read more

Going on my 3rd day training. So far the first two days have been kicking my ass but I like the pace. Constantly moving(cardio + exercises), learning combos, and footwork. my instructor Angel, is correcting me whenever I'm not doing the movements right or hitting properly. He wants to make sure my fundamentals are 100%, so I can see he's setting me up for success and a great foundation. My girlfriend and the kiddos love it as well and are excited to keep going. If you're looking for a place to bring your kids, this is the place. Coach G is awesome and does a great job keeping the kids engaged and wanting to learn more. Can't wait to see how much we improve over the next few month. Thank you to all the staff for making this a great experience so far! read more

Grampa's boxing gym is without one of the best gyms I've ever been to. The minute you walk in you instantly feel the welcoming vibe you don't feel in other places. I've been training with Vaughn who's an excellent trainer alongside Jessica and the rest of the GBG family who truly push you and keep your best interests in mind. Aside from forming a healthy relationship with yourself, you're able to connect with all sorts of people who become like family. If you want a place to relieve stress and better yourself physically and mentally - Grampa's is a go to!!! read more

I don't know if it's possible to articulate in one post how amazing GBG is. I've been around (and I mean gyms!) and I have never felt more at home. From the moment you walk-in, you're greeted by staff, who is now more like family. You're not just another "membership;" the owner and the coaches notice you're progress, when you're not there, and makes you feel like part of the family. An added bonus is my coach, Vaughn aka Alex aka El Diablo. I've been with him for a few years now, and he's worth the transitioning. No matter how many clients he has, he will text you/email/stop by your house if you don't show up! I have never met a coach/trainer who cares more about my progress than he does. If your coach doesn't work harder than you do, find a new one! read more

Love the staff here! I came in for a month membership and loved every workout!! They are also very flexible since I travel often. I was able to pay for 1 month at a time so I can make sure to get the most out of each payment. I'll definitely be back!! read more

I began training with alex about 4 weeks ago I would say it has been the best experiences physically I went from 339lbs to a whopping 313lbs I move a lot better LOOK and feel alot better. the environment is really up lifting, it has a family feel to it I am really grateful for GPB and definitely recommend to any one looking for a gym. I went around the oc area and this gym was the cleanest top it off had the most equipment fully loaded with 2 boxing rings. read more

I made it to my second day today and although I was sore from yesterday, the workout felt good. Coach Jessica is flexible, knowledgeable, and genuine with her approach. Having a last minute change in my availability tonight, I was STILL able to get in a short but intense workout. Jessica was understanding of my time limit and made it work! I was impressed and motivated to keep going. From the very beginning, everyone from Maria, Ingrid, Jessica to even other trainers have been welcoming, friendly and most importantly non-judgmental. It is definitely a family friendly environment. Looking forward to more workouts and positive results. read more

Let me tell you something, if you want to learn to box, or you already know how, but want to better your skills, or you just want to get in shape, you're in the right spot. I LOVE this gym. Everyone is super friendly, family oriented place. Every single boxer here is respectful whether they know you or not. I've seen pro boxers come through the doors every once in a while, I've seen amateur matches. Great service from Grandma and Grampa, always looking out for everyone. You don't need to go anywhere else, this is the #1 boxing gym in the county! ! Hands down! Also, great for all ages 7+ read more

Been a member for 5 years after moving to California. Great facility, equipment, and plenty of space. I especially enjoy the family business vibe and the fun and friendly atmosphere. read more

It's been over a year & training at this gym is one of the best decisions I've made. Walking into a gym that makes you feel so welcoming is always such a great feeling. Seeing Gramma & Grampa who are so sweet to anyone walking in makes me feel at home. Through out this year, I've been working out with both Jessica & David who have so much patience for me & always push me to go harder at the gym to accomplish my goals. Beginning with boxing to even just the basics. It's a great day going to the gym, working with two individuals who are so dedicated to what they do & making sure I feel at 100% during every move that I make. read more

I hurt my ankle doing Muay Thai so decided to come here and work on my boxing technique while recovering. Did not like the vibe at all. Girl at the front was pretty dismissive. I told her I wanted to work one on one with a trainer I saw on her IG a couple weeks back. She goes "oh that was you that messaged me about that? He only trains his son" which is fine but I'm thinking if you saw my message why didn't you just reply? Red flag #1. I came for a private but was pushed into in a group class doing hiit jumping rope and heavy bag work (with bad ankle). They don't listen. After rounds of push ups, windsprints, jumping rope and solo bag work I finally do a round with the trainer on pads and naturally get winded and the chick goes "see, you don't even need a private yet"...as any of that had any correlation to a good technique focused private session. I see why people bring their own trainers. I'll give one star because the trainer was nice and if you're looking for cardio focused boxing or you're a beginner it's probably a good place for you. If you're really trying to get your punches and movement broken down and getting some good private work, go elsewhere or bring your own trainer. You would think a place with so many fees would listen a little better since they love money so much. I'll have to try somewhere else. read more

This place is absolutely incredible! The gym itself is huge and well equipped with several heavy bags and double end bags. There's even a section in the back with a squat rack, bench press, dumbbells and kettlebells. All the staff are very friendly, it definitely has a family type environment. Jessica even approached me on my first day to make sure I felt welcomed. The clientele here ranges very widely. There are pros, beginners, people looking get in shape or stay in shape, older folks, middle age, children, several women, just all walks of life. Whatever your goals may be, I guarantee GBG will be able to help. read more
