Undercard

Fantastic experience: Undercard Boxing Gym in Bondi Junction is hands down one of the best boxing gyms around! The atmosphere is electric, the facilities are top-notch, and the training is next level. A special shoutout to Jasper, who is an exceptional trainer—his knowledge, technique, and ability to push you while keeping things fun make every session worth it. Whether you’re a beginner or experienced, he knows exactly how to tailor the workout to help you improve. Highly recommend this gym for anyone looking to get fitter, stronger, and sharpen their skills!

Fantastic experience: After not training for several year, I decided to give Undercard a go. The staff/ trainers were extremely friendly and supportive. The program they run allows for beginners and experienced people and for you to work at you own pace.

Fantastic experience: Have been doing the 10 class trial and have loved every class at undercard so far. The classes are very challenging but so fun and the instructors are so helpful with technique and motivation to really push you. After 6 classes I’ve already noticed my fitness improving and there is such a great community and vibe, even as a beginner. Couldn’t recommend this enough!

Fantastic experience: Loving the Undercard experience, it's hard, fast and fun. Six sessions down and already feeling stronger and fitter thanks to the intense mix of boxing, conditioning and strength routines.

Fantastic experience: Accessible to people of all fitness levels but guaranteed to leave you absolutely drained. Good community feel, trainers are excellent (as are the tunes!)

Fantastic experience: I started training at Undercard Boxing in Bondi based on my partner's recommendation. As a personal trainer, she has a keen sense for good programming, and after just one session, she was raving about the classes. I decided to give it a try and signed up for the 10-class intro package. After a couple of sessions, I started getting into the rhythm of the workouts and have since enjoyed the atmosphere and the support from both the trainers and fellow members. The classes are challenging, but you notice your progress quickly. I’ve seen a noticeable improvement in my fitness, whether I’m attending other fitness classes or training on my own. This is the first gym review I’ve written, but I felt it was definitely worth sharing the positive results I’ve experienced at Undercard. The environment is welcoming, the trainers are knowledgeable, and overall, it’s been an awesome experience

Fantastic experience: Just completed a two week trial at undercard and am already excited to continue. Loved the mixture of boxing and running and sprinkling in strength, too. Classes are super tough but you come out feeling on top of the world; exactly what I want for 2025.

Fantastic experience: Undercard is not for the faint hearted! I had tried a few gyms around Bondi and these workouts challenge me the most. I feel proud after each one and then energised later during the day. Trainers and staff are great and they really help you to give your best. Go check it out!

Fantastic experience: I absolutely love this boxing gym. I’m always so excited to go there. It‘s really personal and they make you feel very comfortable as a beginner. It’s just so much fun, diverse and the time goes by so fast. Can only recommend to try it out:)

Fantastic experience: Great vibes, community and workouts that really push you to the limit. I loved the variety of classes throughout the week. Joshua took time to refresh boxing basics with me before my first class, and all the instructors were very welcoming and friendly. Definitely one of the best gyms for group fitness in Sydney.

Fantastic experience: These classes will transform your fitness. I am not into cardio at all, but love these sessions! The trainers motivate you so much (I haven’t experienced this in YEARS) and the member community is super inclusive, all working professionals. Plus the owners are super considerate and take care of you

Fantastic experience: Never boxed before starting here and couldn't recommend Undercard enough! The trainers are next level and make every class enjoyable. They have built a great community in undercard.

Fantastic experience: This crew and the classes are amazing!!! Honestly it’s reignited my passion for boxing and group fitness Thanks guys

Fantastic experience: I have loved this gym so far. The classes are some of the hardest workouts I’ve done before but so rewarding and they push you to your limit!

Fantastic experience: Small studio with a big heart! Kes Commerford delivers an intense cardio workout that really packs a punch, all while maintaining excellent technique. Highly recommend!

Fantastic experience: Undercard is a great place to train. Jasper and the team do an awesome job making the classes fun and engaging. I always look forward to the early morning Saturday classes with Jasper.

Fantastic experience: One of the best gyms I have been to!

Fantastic experience: Of all the gyms in Sydney I have tried, this gym consistently challenges me the most! I love it

Fantastic experience: Undercard gym is great, classes are unreal! So tough but enjoyable at the same time.

Fantastic experience: High intensity classes with a mix of boxing, cardio on curved treadmills & weights. Friendly trainers + good music + plenty of car parking nearby.

Fantastic experience: I followed Josh to Undercard as he is an awesome trainer. It is now wonderful to be part of the crew with Kes, Em and others. The community vibe makes even the toughest workouts fun.

Fantastic experience: Absolutely love this place! Undercard is the only gym I have enjoyed going to. Their classes will have you sweating and pushing you to the edge of your limits. Everyone is super friendly and ready to cheer you on when you think you can't possibly do one more burpee… and Kes and Nads are absolute legends and will push you in your class and correct anything you’re doing wrong! Would 100% recommend! (coming from a non gym goer & non boxer before UC, I’m now hook-ed!)

Fantastic experience: Sweet gym. The instructors are super knowledgeable and motivating. The spacing & class size are perfect, and the format is high intensity, though you can moderate your weights, etc for different ability levels. I feel like I start my day on a high after I finish the morning classes. Would highly recommend

Fantastic experience: Best boxing studio in Sydney!

Fantastic experience: I was initially quite nervous to join as I've never boxed before but the team at Undercard put me at ease right away. It's such a friendly & welcoming environment for everyone. The music & lights get you pumped & you'll sweat like never before

Fantastic experience: I felt very welcomed. They give you a 1on1 pre-lesson training for your first time. All skills welcomed. Great energy but most importantly good people.

Fantastic experience: Awesome staff, Awesome class, just Awesome!

Fantastic experience: The best workout in all of Sydney! Whether you’re a first timer or experienced there are new challenges at every session. The coaches are so committed and friendly. 12/10!

Fantastic experience: Undercard is the best workout in Sydney! Always challenging but with modifications available to suit everyone. I love the combination of boxing, strength and cardio - makes for a great session every time, and the trainers are all so energetic and awesome!

Fantastic experience: Love the fast paced combo of the treadmill and boxing!

Fantastic experience: One of my favourite workouts. A great combination of boxing, strength and cardio, Undercard pushes you to your limits. All the trainers are friendly and encouraging and focused on ensuring everyone is applying the correct techniques in boxing and strength exercises. There is a great atmosphere, great music and a very welcoming vibe to the whole gym - highly recommend trying it out!

Fantastic experience: Best workout in Sydney. Great structure, perfect balance between strength and cardio. I love an intense workout and this place always delivers!

Fantastic experience: Love undercard and would definitely recommend. The trainers are great and always push me to get the most out of my workout. 5 stars for always bringing a hard session with a great vibe and music playlist to match

Fantastic experience: Perfectly located at Bondi Junction, sweaty classes and great trainers ! Highly recommend

Fantastic experience: Awesome space - even better coaching team. Can’t recommend this place enough.

Fantastic experience: Undercard is one of the hardest and best workouts in Sydney. I absolutely love the combination of running, lifting and hitting the bag that undercard provides. The music is also always on point and the staff are the best in the business.

Fantastic experience: I have been training regularly with the Undercard team for over a year now. Great trainers, excellent setup and some of the nicest fellow Undercarders to sweat with each morning! I can’t recommend the place highly enough…

Positive experience: ***Positives: 1. Great HIIT workouts with some beats, low weights and boxing combos. 2. Good caring coach who is patient and takes the time to introduce new people to the machine and punches. 3. Provides boxing gloves and thin gloves to make your knuckles feel more comfortable when wearing gloves. ***Points of improvements: 1. Choose slow beats for long combo punches; 2. Choose fast beats for short combos; 3. Choose powerful beats for power shots; 4. Work station needs lines to clearly separate workout areas for each member. (Review to be updated when there are improvements made)

Fantastic experience: Best boxing experience! Excellent coaches and classes. Nothing compares to being under the orange lights!!Love it, love it, love it!

Fantastic experience: Best trainer and team. Great, positive vibe, trainers are attentive, stylish premise and amazing coffee. I feel so happy to have found Undercard boxing!

Fantastic experience: Undercard is the best work out! I absolutely love the various classes and look forward to training each week. The added bonus is.... the staff are the best guys as well!

Fantastic experience: Undercard sessions are hard, you must pace yourself, you will empty the tank and you will walk out feeling like a badass. If you like boxing and want to smash calories like a wrecking ball this place is THE BEST!

Fantastic experience: Seriously great training in friendly, safe and inspiring environment

Fantastic experience: Easily the hardest & best workout in the world.

Fantastic experience: Undercard (boxing or strength/conditioning) classes are not only one of the most intense workout sessions you will find in Sydney, but also one of the best run group classes I have experienced. The staff are professional and actively push you whatever your fitness level/goal, and all the trainers are super nice too. The facilities are first rate in particular the boxing area downstairs with water filled punching bags. Undercard provide gloves and a towel which is always nice and the change rooms are very clean and modern. Highly recommended and I'm personally always looking forward to my next class.

Fantastic experience: Great gym and atmosphere with friendly staff. Being a bigger person was a bit nervous attending my first time seeing all the fit people there. Although the training can be intense, the nerves were not justified, the trainers are great at adjusting their programs for all levels.

Fantastic experience: My favourite place for a tough workout! Push yourself to not only get fitter but learn a new skill. Great trainers and equipment (even if the skillmill kills me every time) and an all round supportive vibe!

Fantastic experience: Consistently great workouts; experienced trainers who know their stuff. Clean, modern gym and the best boxing in Sydney. Get in there!

Fantastic experience: Cannot fault. Amazing instructors, very intense workouts. Combination of boxing/skillmill/weights/cardio machines, makes for something unique to this gym. Professionally run and well-organised. I have to disagree with the comment below as to lack of technique instruction and confusion. That has not been my experience at all, and in fact Alicia (one of the instructors, who is absolutely amazing and a great trainer) on a recent occasion took all the newbies down before class commenced to give them separate small group instruction as to technique. The booking system is simple and works well.

Fantastic experience: Undercard is the perfect space and environment for anyone searching for cardio, conditioning, mix up their training or to get started on transforming their fitness. The trainers are friendly and will certainly pull 100% out of you each and every session. Egos are checked at the door so it’s a relaxed and fitness focused environment. Whether you’re a meathead looking to get some excellent cardio/ conditioning or just looking to keep lean and burn some extra calories this is hands up the best class based gym in Sydney.

Fantastic experience: I have been with Undercard and Kes prior for almost 15 years. I find this gym the best to push me to my personal best and all the trainers friendly and really good. Couldn't more highly recommend this gym

Fantastic experience: Love coming to Undercard - the classes are always so amazing and the instructors have the best energy! Highly recommend Undercard for an incredible work out x

Fantastic experience: If you’re looking for a fun and challenging workout, I highly recommend Undercard! I love the atmosphere and intensity of Undercard's classes and the instructors do a great job at motivating everyone to get the most out of their workout. Their equipment and facilities are also very clean and well maintained.

Fantastic experience: A great team that keeps you motivated during classes as well as correcting postural and technique errors that arise during training, which is both unique and challenging. As a longstanding member I cannot recommend this gym and the staff highly enough...your enthusiasm and energy is infectious.

Fantastic experience: Undercard is the best high intensity workout you’ll get in Sydney (possibly anywhere!). The studio is absolutely beautiful, from the moment you walk in you can see how much effort has gone in to its form & function. The equipment is all new, well looked after and available pre class for you to stretch/ warm up - big bonus! The best part about Undercard is the die hard passionate trainers, they’re legit the nicest people who ALWAYS push me to give 110% - I finish thinking I’ve just done the hardest PT session of my life! There are amenities available that are clean and tidy with hair products available (haven’t used these but it looks super fancy). Oh, also getting a towel to workout with each time is a big plus, along with being able to get a coffee or smoothie post workout. I highly recommend this gym & absolutely love it!

Fantastic experience: My favourite gym session of the week, great vibe, friendly staff and awesome classes. The trainers are super motivating, personable and make you feel apart of the team. If you enjoy high intensity mixed with boxing and cardio then i highly recommend joining a class.

Fantastic experience: I absolutely love my undercard boxing sessions every week. There is not a workout in Sydney that compares. Since training at Undercard I’ve become so much fitter and leaner, and my boxing technique has improved tenfold. The team are so friendly and welcoming, it’s like being part of a family!

Fantastic experience: Great atmosphere, trainers and workouts. If you want to get fit and work on your boxing skills, this is the best place to go!

Fantastic experience: Going to Undercard is always one of the highlights of my week. The equipment and trainers are second to none and there's an awesome sense of community. You leave every class feeling wrecked but glad that you did it. Highly recommend.

Fantastic experience: The best workouts, amazing trainers and an overall awesome environment. Original and always challenging, Undercard is a gym like non other.

Fantastic experience: Great equipment, enthusiastic, hard working coaches. Workouts are really tough but fun!

Fantastic experience: Undercard is the G.O.A.T. There's really no other studio in Sydney that offers this intensity of workout, technical training skills and quality of trainers. I started with Undercard over a year ago and can honestly say I'm a better person in all ways because of it. The boxing classes are unparalleled and push me to my limit every time. I thought I was fit when I started, but this style of training has taken my fitness to another level. I've learnt how to train hard and I absolutely love how everyone who comes is there to do the same thing. There's absolutely no pretentiousness. Just a super lovely group of people that love working out, growing and becoming stronger. If you want to get serious about your fitness and boxing, book a class with Kes or a PT sesh with him on the pads. Do a Contender class with Jess to become an absolute weapon (like her). And definitely do Alicia's classes to push through any mental block or physical limit that's been holding you back. I also highly recommend doing a boxing workshop with pro Luke Jackson to sharpen your technique.

Fantastic experience: This is a fun but really hard workout in a very cool gym. Easily the best workout I have ever had in Sydney. Consistently good training.

Fantastic experience: I love everything about this place. The staff are friendly, knowledgeable and the facilities are fantastic. The workouts are high energy and no two are ever the same. If you like a good workout, then I can’t recommend Undercard enough.

Negative experience: If you want to actually box and learn something do NOT come here. They should be more clear that this is NOT boxing it’s a strange combo of boxercise ? They offer absolutely no corrections throughout class on boxing or form during weights which can lead to serious injury. The instructor stood in the middle of the class just jumping up and down. Not only was this not a real boxing class they also throw in treadmill running and weights. I really wish they didn’t try to be everything to everyone and just stuck to one thing and got good at that. You can do boxing and conditioning on the mats and that’s more than enough to make a class effective and enjoyable. The class was SO confusing - I’ve boxed at real boxing gyms in the past and this class was just all wrong. The combinations changed before you could wrap your head around what the instructor was telling you to do. I couldn’t hear her and the combos were on a board behind you so you couldn’t even see it. Couldn’t hear anything on the treds either. The showers had no shampoo or conditioner and had no towels - if you’re going to charge boutique prices at least have basic amenities. The worst part is I bought an over priced trial (2 classes) and used one class had a terrible experience and their booking system didn’t let me use the second so never got to give it another chance.

Fantastic experience: Love this place . Great trainers, great atmosphere and awesome sessions that will leave you feeling ready to take on the world

Fantastic experience: Do yourself a favour, check out this space. The legends that run this place have hit it out of the park. Every session is amazing and I guarantee you will leave feeling that you can tackle anything the day brings at you. Also the post workout smoothies are amazing.

Fantastic experience: Absolute killer workout! The class is just as intense as a private PT (if not more!). It's the perfect balance between work on the bags and interval training on the floor. Definitely recommend, especially for those interested in getting into boxing. The trainers are highly skilled and know what they're talking about. Oh and the shower heads in the bathroom are pretty epic too and the breakfast smoothie goes alright!

Fantastic experience: Undercard has some of the best facilities I’ve seen and an even better culture. Visiting Sydney from Melbourne for 4 days we had no real intention of training whilst there. But after doing an intro session with Zach we were hooked training 3 out of 4 days of our holiday. I can confidently say this is one of the best boxing/cross training hybrid sessions I have ever done and loved the energy and style of training that undercard provides. Looking forward to the next visit to Sydney to do it all again.

Fantastic experience: Incredible workout with great instructors - one of the few places in Sydney that pushes you but also focuses on technique. Couldn't recommend more.

Fantastic experience: If you’re looking for an experience, atmosphere, community, a damn good workout and all round positive vibes — this is your place. EPIC team, EPIC spot, EPIC music, EPIC workout. A truly unique, one of a kind and totally unrivalled gym. GET INVOLVED #STRAPSZN

Fantastic experience: What an amazing Boxing space. I was in Sydney from NZ and wanted to try something different. The space was inviting and the Instructor I had was really knowledgeable and was really good at explaining moves and techniques. The shower and toilet area smelt clean and fresh which was really good and I also had an amazing green smoothie after my work out. I highly recommend people to go and check out this space, as you will not be disappointed. Highly recommend

Fantastic experience: The boxing is TOUGH, the training is HARD, Undercard is fabulous - i've caught myself hovering and chatting after class with a detox smoothy and an espresso in a post train , double handed daze. Consistently burnt about 800 cals per 45 min class and beautifully hitting the bag just once in a session keeps me coming back .. To me, Kes is the best trainer in Australia and a legend. His crew are family and his new behemoth of a gym is a cool spot to thump a bag and get seriously fit. I used to be 110kg after swilling wine, chips and cocaine in London for years, now 76kg - better weight , happier , snappier , sober - Thanks to Kes & co. . & i also have a really nice box gap.

Fantastic experience: A super good workout that’s also lots of fun! I love that I get my own bag and equipment for the session so I can go at a pace that works for me. Such a gorgeous, warm and welcoming team and atmosphere.

Fantastic experience: An amazing workout in an amazing environment. As someone who has never boxed before, I found the class easy to follow as the instructors are excellent at demonstrating the punches in a way that's simple to understand. This class is the perfect mix of intense cardio ( which I love ) and then different combinations on the bags. Would absolutely recommend and since going I have noticed a massive change in my fitness.
