Tried calling them a few times. But every time I spoke to someone they said I would get a call back from Angel who is the owner. It's been over 2 month and I haven't heard from anyone. So much for their stellar five-star reviews. Psh! Update: The fact that the owner was so quick to call my review 'petty' when he didn't return my calls for months goes to show the line he's ready to walk just for the sake of maintaining a false reputation on yelp. It also speaks volumes of how mindful he is of other's time. We all come from a different place in our respective lives Mr Owner and all I expected was an acknowledgement. P.S: Don't assume people are stupid enough to tell the different between a genuine apology and a snarky comment. I hope have a fabulous day! read more

Boston Underground Strength Training is a godsend in the sports fitness community. I spoke with Angel on the phone to discuss my goals, recovering from a multi-year shoulder injury and getting back onto the path to powerlifting, and we set up an in-person consultation. The consultation was quick and thorough and we set up a plan of action to get me back in shape to lift heavy again. It took a while but trusting Angel and the other trainers here was the best thing I have ever done. I want to say it took about 8 months of recovery based training with the semi-private training group but I no longer have the chronic shoulder pain that I first walked in with. Since coming to Boston Underground Strength Training and going through the recovery training I have competed in three powerlifting meets and have been performing better than I could ever imagined thanks to the excellent programming and coaching provided here. Without Boston Underground I would never have been able to recover from my shoulder injury and probably would have had to give up on my favorite hobby. I wish I could rate this higher than 5/5. -Kyle Campofiore read more

This is a much-needed and past-due review for one of the best gyms I've had the pleasure to train in. I joined BUST as soon as gyms reopened this past summer. I trained mostly with Mark and Angel. They are excellent trainers, know their stuff, are dedicated to their work, and make the space a really enjoyable and positive environment to train in. They go above and beyond in helping their clients reach their goals. Angel even created home workouts for me that progressed with my program. They're really attentive to how you're doing, what your strengths and weaknesses are, and how to help you improve. They push you in the best way that works for you. Angel was also really pro-active in checking in between each session, especially in the beginning. The work-outs are really efficient. Probably the most effective 45 minutes I've ever spent training, each session. For several years, I was an avid gym-goer and long-distance cyclist but fell into an office lifestyle rut. I felt overall stronger and in better shape quicker than in any previous self-guided training or any online/app-based program. I also learned a lot about proper technique, form, recovery, and pace. Finally, during the pandemic, of several of the gyms I looked into in the area, I felt that BUST takes the most initiative in safety. They have a set-up and routine that I felt completely at ease in. I had to shift gears financially due to a family emergency, but genuinely miss training here and would return in a heartbeat. If you are committed to fitness, this is a fantastic place to join. read more

Angel and Jon at Boston Underground Strength Training provide a very positive and individually-focused training experience. I've been a member for three months, and I can see changes in areas of my body that I could not "progress" in the past. I've also seen changes in my attitude: The focus Angel and Jon share carries over to the rest of my life outside the studio. Sometimes small, disciplined training centers can be intimidating. The same can be true when you walk into a large training facility and it appears as if everyone is already below 10% body fat and running marathons. I don't get any of that vibe here: Just the opposite. I'm challenged to master movements and practices consciously and patiently. My programs are individually designed each month to challenge me sufficiently, to keep my mind and body engaged while preparing me for more challenging and interesting movements and programs in the future, and to disprove myths I had about my limitations. If you want a personalized experience in a small group environment (or 1-1 personal training, which is also available), look no further. There's plenty of parking. The studio is exceptionally clean and well organized. Angel and Jon focus exclusively on our workouts (versus looking at their cell phones or talking amongst themselves: Both conditions I've observed frequently with "trainers" in other facilities in the past.) read more

Thanks to Boston Underground Strength Training, I am stronger and more confident in my body now at 35 than I have ever been in my life. In high school, I was too embarrassed and ashamed to participate in any sports. I'm now a high school teacher, and today I proudly played in the student vs. staff kickball game. I could not have done that without the support, focus, training, and care that I've been receiving at the Underground for two years now. The coaches here listen to my goals, adapt to my needs, and take the time to figure out how to work with my dyspraxia. The Underground is truly a gym for everyone - seasoned athletes and novices alike. Thank you, Angel, for fostering a community that allows me to finally feel comfortable in a gym! read more

After 16 years or so of no real physical activity, I finally decided it was time to stop being so lazy and sedentary. After looking around at dozens of options, my husband and I stopped by to meet with Angel and discuss their semi-private training. I figured personal training would force accountability to make sure I stick with it, and teach me how to work out properly without injuring myself. I couldn't have asked for a better place! Even while struggling to get out of bed after day 1, I found myself anxious and excited for our next workout. While it's only been 1 month so far, that excitement has only strengthened. I cannot recommend Angel and Jon enough. The positive energy they exude is infectious, and they truly care about everyone that walks through their door. As someone who knew literally nothing about exercise, and was incredibly embarrassed about that -- working out with them has given me an immense amount of confidence. My workout is very clearly tailored towards what I can handle, while making sure I have the freedom to push myself without overdoing it. I've seen major improvement in myself in just one month, and will continue for the foreseeable future. Especially with their current rates, I feel as if I've hit the lottery. They are absolutely worth a try -- you'll likely be hooked after the first visit, much like myself! read more

Boston Underground Strength Training is truly the most special and amazing place. The owner, Angel, welcomes you in with open arms and truly listens to you, cares about you, and wants you to succeed. I love so much about this place--but the biggest thing that sets this gym apart is the attitude of all of the trainers and members. Hard work, positivity, respect, focus--every person works their heart out at every workout, and cheers on the person next to them. Angel and Jon work so hard to make sure each member feels good, physically and mentally. During the Strength Camps, the trainers are right there next to you, motivating you, making sure you execute everything properly, and encouraging you to do the best YOU can do. I love the focus on mental toughness, and the no-nonsense exercises that make the hour-long Camps go by so quickly. As a mom of a toddler, I never thought I would have the motivation to hop out of bed at 5am three mornings a week to haul my bum (consistently) to the gym before a long workday - BUT I actually look forward (!!) to every workout at Boston Underground Strength Training. The confidence I've found through this gym has translated to every area of my life. I've gotten stronger, leaner, and found such a great community of people who are all looking to push themselves and reach their goals. Angel has created the most inclusive, awesome, caring and motivating environment, and I only wish I'd joined sooner! Other things that make the Underground special: --Every class starts exactly on time. The 6am Camps start the moment the clock turns from 5:59 to 6:00. No nonsense/time-wasting. --The gym is impeccably clean. --The atmosphere during a workout is SO motivating. There is no lallygagging around/cell phone checking/etc. I am always shocked at how quickly the hour goes. --The trainers demonstrate every exercise beforehand, and pace the gym the entirety of the workout to make sure everyone is doing everything correctly. This makes me feel like I can take take risks and push myself (add weight/try something new/etc.), because the trainers are so present/supportive. --If you have any type of injury/soreness/etc., the trainers will modify everything for you and go out of their way to give you stretches to help you recover. read more

I take both semi-private training and classes at Boston Underground Strength Training, and I wish I could give them more than 5 stars because they are just that amazing. The semi-private classes are super affordable for what they are, which is essentially almost a private lesson with excellent trainers. Your workout is targeted to your goals, and updated monthly, so if your goals change or you want to focus on something specific they will set that up for you. You will get more attention as you start your program and don't know what you are doing but once you are self-sufficient they will let you do your thing and just stop by if your form needs correction or if they have any comments on how you can get more out of the move. As for the classes- I had been going to a different gym for their high intensity interval training classes because, well, BUST doesn't have treadmills. But I don't know what I was thinking. I hate treadmills. BUST offers a metabolic strength class which gives me the same HIIT workout with no treadmills! Rowing, jumping rope, pushing sleds, lifting weights- you'll get that heart rate into the EPOC zone while having fun the whole time. (And getting coached and corrected on form if you've never done some of these moves before) If you love treadmills don't worry, you can still do your treads on your own time at one of those $10/month places while working at BUST on strengthening your lower body to improve your speed on those inclines. I probably shouldn't even be telling you about this awesome class because I don't want it to fill up so I can't get in. Finally, I can't write a review without mentioning the excellent coaches who really know their sh*t, motivate me and make me smile and laugh every time. And of course, Angel, the owner, makes sure every client feels like part of his family. It's just a wonderful environment and if you are nervous about stepping into a strength training gym with scary barbells don't be. You'll quickly love it just as much as I do. read more

After three months of training at Boston Underground Strength Training, it's safe to say that I'm hooked. As a lifelong athlete, I can say that these bootcamp sessions are the most effective workouts I've ever done. Angel and Jon design challenging full-body programs that promote balance and overall functional strength. Modified workouts allow newbies to train alongside seasoned veterans in an environment where everyone can improve at their own pace. Small class sizes allow for plenty of individual focus on proper form and safety. The facility is spotless and includes brand new training equipment. Simply put, if you're looking to take your fitness to the next level, do yourself a favor and check out Boston Underground Strength Training. read more

Boston Underground Strength Training - Trainers Near Me - Waltham, Massachusetts

Boston Underground is, hands down, the best gym I have ever been to. Prior to becoming a member, I belonged to a more "typical" gym where I felt directionless, didn't know where to begin or end, and generally left feeling defeated. The first workout at the BUST changed all that for me, and I only became more confident as the months went on. Angel and his team are truly dedicated to your success and always focus on the whole person. They push you, but it is obvious that it comes from a compassionate place. They quickly learn your strengths and adjust flexibly to your needs. Angel has created a pretty amazing community here. You won't regret making this choice. Have you signed up yet? read more

I just finished my first week of strength camp at this gym and I can honestly say it was one of the best workouts I have ever had. Angel (the owner) and the other trainers are very professional and encouraging during your workout. Angel makes sure to ask everyone when they enter the gym if they are sore at all and if there is anything bothering them that they need to work on. These camps are great for beginners to experts because they target every body part and it is go at your own pace. At the last class I attended we did squats, kettle ball, running, sled push, weight carrying, and bench press. Whenever I needed help with my form or the station to be showed to me again One of the trainers had no problem taking the time to show me how to do something. After last class Angel even took the time to help me with my squats. I highly recommend this place to someone who is just starting to get back into working out and needs the extra push, someone who wants to do something other than run on a treadmill all day, and someone who wants to have fun while they workout! Definitely check out Boston Underground Strength Training you'll be sore but you wont be sorry! read more

After reading all of the great reviews on Yelp, I decided to try out Boston Underground Strength Training. I've been going regularly since February and I LOVE IT! I was a rugby player in college, and I've always loved working out and training with a group. The group classes really fulfill the team aspect that I had been missing since I stopped playing a team sport. Angel, John, and Lyda are great trainers, and they are so passionate about everyone's form and personal health. They make a point of coming around at the beginning of class to check on how everyone is feeling, which is something I had never seen before in any sort of fitness class I'd been to. The workouts are challenging, and they are dynamic enough that people of various fitness levels can do the same moves with different weights or other added difficulty. The people who attend the classes are so supportive. We help push each other during the workouts, in addition to Angel, John, and Lyda encouraging us! I have been so happy to make BUST a part of my weekly routine. I've definitely gotten a lot stronger, my technique has improved, and my posture is noticeably better. I would highly recommend Boston Underground Strength Training to anyone looking to have fun and be challenged at the same time! read more

I have been participating in the semi-private trainings here for 3 month now and saw significant improvement of my deadlifts and squats, with my deadlift max going from 140+ to 190+. The gym is very clean and organized. I love the fact the scheduling is very easy with the mindbody studio app that they use. Plus, you can always cancel a day before if you have something come up. The other fellow trainees I have come across so far all seemed friendly. Parking is easy as they have street parking as well as a small parking lot next to the building. The trainers are the biggest assets of this place - very knowledgeable, approachable, helpful, and understanding. I really enjoyed working out here. read more

When I first joined BUST 6 months ago I had never lifted a weight in my life and was terrified of "the other side of the gym." I was so nervous that I wouldn't fit in. Fortunately, this gym is the most welcoming environment I've ever experienced and there was no judgement from anyone from the first day I joined. There are a lot of small group gyms in the area that are probably similar, but what really stands them apart from the competition are the people who run it. Jon and Angel are the most patient, supportive, and caring people I know. The first couple of weeks were incredibly difficult for me, but they worked with me and modified my personal programs until I was strong enough to do everything as planned on my own. Not once did I feel like I didn't belong, even though I didn't know the difference between a dumbbell and a kettlebell on my first day. I can't recommend this place enough. For the first time in my life I enjoy going to the gym. It changed my life. read more

Oh man, I'm sore today! And I have the feeling I'm only going to get sorer as the day goes on. That's a great thing! Angel gave my sister and I a great bootcamp workout, pushing us past our limits but always paying attention to safe technique. He's really supportive and we had a lot of fun! I highly recommend :-) read more

I've been going to Boston Underground for about 8 months now, and couldn't be happier! Moving from Connecticut to Boston for grad school I wanted to find a gym that fit my schedule and provided a great workout. What I found was that and much more. I became part of a community that was welcoming and geared to helping everyone reach their goals. The coaches are very knowledgeable, making sure that the correct form is being used as well as giving you a workout to challenge yourself. I can't say enough about this gym, try it out, you won't be disappointed! read more

Boston underground is hands down one of the best gyms I've ever tried. I've never been motivated to strength train or even knew how to do it. Once I read all the amazing reviews for Angel and Jon I knew it was worth trying. They made me feel comfortable while learning all about it. They make sure your form is perfect to avoid any injuries. When I was in a recent car accident they were so patient and helped me go my own pace even during the camps. Everyone there is encouraging and I look forward to going. I feel more confident that I learned something that I doubted I could do. They also are so friendly and care to learn more about you and your goals. We even signed up as a team for the spartan race at Fenway and everyone tried to stay together. If you have the opportunity to try it I highly recommend it!! read more

Stopped by Boston Underground Strength training for the first time yesterday. Owner Angel accessed my sister and my levels (beginner all the way) and tailored a mini-bootcamp just for us. I was a bit intimidated by the prospect of strength training, but Angel was supportive and instructive. Definitely recommended! read more

It took me 5 months to find the courage to join this gym and I regret not starting sooner! If you're thinking about becoming a part of this fitness family, don't hesitate going forward in doing so. Before this gym, my workout life was becoming routine. In looking for ways to learn how to improve my knowledge on strength training in order to challenge myself and achieve more with my body, I came across this gym. Throughout my training experience at Boston Underground, my confidence surrounding fitness has sky-rocketed. Angel and Jon are phenomenal trainers! I cannot thank them enough for what they have done for me. Because they focus on proper form/technique makes every single workout session effective. Not only will you achieve major body gains, but you'll gain fitness techniques that you can apply anywhere. In addition to all this, I also gained a fitness community of wonderful encouraging people. The members of this gym are serious about pushing and improving themselves, but are also fun and great to be around. The environment at Boston Underground is amazing and I couldn't have asked for a better gym experience! read more

If you're looking to feel inspired, empowered, and confident, I have to recommend Boston Underground Strength Training and specifically, the coaches who make it what it is. Whether you are training for that big race, or hoping to establish some positive habits, this is a place to build a foundation and achieve your goals. I can't say enough great things about this community! read more

Bottom line, if you are looking to get stronger, to be challenged, to work hard, and to have fun at the same time - Boston Underground Strength is the place for you. Angel and Jon provide individual attention, feedback and guidance on proper form. They truly care about your progress and your goals. The programs are changed frequently (so you will never be bored). I started training at Boston Underground Strength in February, and have to say that the camp I attend is, by far, the best and most challenging workout I have ever had. Angel and Jon foster a great sense of camaraderie and people of all ages and abilities are welcomed. You will leave there feeling empowered and energized. read more

I've trained with Jon and Angel for about 3 years. I'm very happy with the results, and I appreciate the variety in the programs that they develop for me. I have fun training with these guys. The gym is set up with just enough simple equipment to get the job done: Dumbbells, barbells, sleds, TRX, kettle bells and med balls all find their way into my programs on a daily basis. They are constantly keeping an eye on my form, which makes me feel confident to push to my limits. If I come in with some pain or something, they'll modify the program as needed or give me specific stretches to follow up with at home. These guys know what they're doing, and I'd happily recommend them to anyone who is looking for some help getting the most out of their workouts. read more

I have been coming to B.U.S.T. since March, attending the strength camps 2x a week. My favorite thing about the programming is that it changes from month to month - Angel and Jon work hard to create programs that are challenging and effective, and they are constantly making sure your form is correct and showing you how to modify if necessary. In the few months I have been attending the strength camps I have increased my strength, but more importantly, I am learning the correct way to perform each exercise, which will help prevent injury. The people are great, the classes will push you, and you will work your butt off and actually have a good time doing it. read more

I started training at Boston Underground Strength Training almost a year ago. I have always been a petite build so had never really committed to a gym and had never lifted weights before because I didn't think I had much of a reason to. Still, looking in shape and being in shape are two very different things. I started with the intention of keeping my body toned for my upcoming wedding, what I have gotten out of it is really beyond what my expectations were. At first, muscles I didn't even know existed were so sore it hurt to even get out of bed in the morning. I stuck through it anyway and I am so happy that I did. The transformation I have seen in my body, as well as my overall health, is astonishing. I am so proud of how far I have come and I have the confidence in my body to prove it. Angel and John are phenomenal trainers, they check in with you before class to make sure you don't have any discomfort, encourage you to keep pushing yourself throughout but also respect you to go at your own pace. They are able to keep an eye on every single member throughout the entire hour long classes and adjust your movements as needed to make sure you stay safe and get the most out of your work out. What's even better is that they know everyone by name and what their goals are, making it a much more personal experience. Even after moving 45 minutes away, I refused to transfer gyms. I strongly believe I wouldn't get the same dedication, teamwork, and support that you do at BUST anywhere else. Highly recommended! read more

I was looking for a change from my mainstream gym & really wanted some guidance by personal trainers. My cousins told me about BUST & I thought I'd sign up for the 1x Strength Camp just to try it out. I definitely wasn't disappointed and now I'm hooked! Angel, John, & Matt definitely helped me get back into shape (especially for my wedding in September), but best of all they've created this community where I've met so many great people. I would 1,000% refer anyone to check it out, especially if they're looking for a positive lifestyle change! read more

I just got through my second workout at Boston Underground. Coming from a person who has not been to a gym in over 6 months, Angel and John give you exactly what you need to get motivated and remember that working out can be fun. It is go at your own pace which makes for a non-intimidating experience (something which has always steered me away from bootcamps/circuit training/group training in the past). Honestly- I would recommend this gym to anyone who wants to get some strength training in while doing so in a fun and extremely supportive environment. Skilled trainers who want nothing but the best for their clients. A+++ read more

Boston underground strength training is one of if not the best gym I have gone too. I have been going here for the past few months and there's nothing bad I can say about it. As a former athlete I was looking for a gym that when I walked into it I knew I was getting a great workout. Every staff member is friendly and helps you out no matter what questions you have. During the group classes, everyone is friendly and helps each other out. I strongly recommend group classes because every class is a new challenge. I wanted to go to a gym that I'm excited to go workout at, not one that's packed after work where you have to wait an hour just to use the squat rack. I highly recommend this gym for the person who wants to push them selves to there best. Once you go once, you will want to keep coming back I guarantee it. read more

I've been working out at the underground for 3 years and every year I better myself. As a college athlete I look forward to summer training because it helps me continue to elevate my level of play. They do an amazing job catering my workout to not only my sport but my position. I go into fall season at my best because of the work I put in during the summer. I wouldn't be the athlete I am without Boston underground. read more

I LOVE this program and the guys that run it! The coaching is hand-on and worth every cent. If you are looking for a specialized program where you get personal attention to achieve your fitness goals, then this is for you. I didn't think I could ever manage a 6:00 am fitness class but I actually look forward to going (most mornings)! Highly recommend. read more

I joined Boston Underground back in February 2016 and I honestly have to say, it has changed my life! I haven't been happier with the changes I have seen with my body and it is all thanks to Angel and Jon and my personal motivation to want to change! I had not worked out since college and not doing anything for 5+ years, I knew I needed to make a lifestyle change and get back into shape. I finally emailed them in February and joined the next day! I started doing the group classes 3x a week, as well as the semi-personal training 1x week. The personal training is amazing!! Angel tailors your program to meet your personal goals and I cannot say enough great things about the results I have seen! Everyone you work out with in the group classes are all incredible individuals and very welcoming too. In my opinion, the classes and training are for all levels- especially if you hadn't seen the inside of a gym in years- like myself. They really get you back on your feet and ensure you are doing each workout properly to avoid injuries! I actually got into a car accident last month and unfortunately injured my back, so I had to take some time off, but when I returned Jon and Angel were great and really took the time to understand what injuries I had and how to modify the exercises for me. I cannot say enough great things about Angel and Jon and whole BUST community!! read more
