Note: If you are currently injured or trying to work through an injury, this is NOT the appropriate option for you at this time. Due to the high pace of our classes and our class structure, we are not able to dedicate all of our time to one specific individual. In this case, we ask that you to start with our Semi-Private Training option as it will be the most suitable option.

I can't recommend this place enough. For the first time in my life I enjoy going to the gym. It changed my life. ~ Hayley H.

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. ~ Adam C.

I've been to a few gyms before BUST, but nothing compares to the kind of results I could see in myself once I started training with these guys! ~ Puneet R.
One thing that I love about this gym is that it focuses on making you the best person you want to be. ~ Kyle B.

Boston Underground Strength Training is truly the most special and amazing place. The owner, Angel, welcomes you in with open arms and 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

This is the best gym I've ever tried, by a large margin. They created a personalized routine based around balance, flexibility and strength, using primarily body weight, focused on improving my ability to do things I want and need to do in everyday life. Plus a relentlessly positive attitude and observable results that gets me actually wanting to get to the gym, something I didn't think was possible anymore.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

For the past 10 months, Angel and Jon have been the main force driving me towards my strength goals. I have been taking semi-private training with them. They quickly made a rapport with me and then kept pushing me in a safe and controlled manner. They would make sure I am using the correct form and a new personalized program every month kept my body warmed up for new challenges.I've been to a few gyms before BUST, but nothing compares to the kind of results I could see in myself once I started training with these guys! I'm so sad that I have to leave them when I moved to Seattle. Hope you guys come over to Seattle soon! You're the best!read more

I made the decision to try out BUST because I became really interested in strength training but had no real prior experience in the technical aspects of lifting and no experience building a training program that I could adhere to. I was previously on a self-managed 3x5 program which I saw some gains through, but as the weight got heavier I really began to question my form and I noticed my confidence in pushing against my limits start to fall. I started looking around for a personal trainer and I was drawn to BUST from the extremely positive reviews that I read online.Since last April I've been enrolled in the semi-private training program once a week and I train outside another 3 days a week following the training program that Angel has created for me. At the end of each 4-week cycle we sit down and talk about my progress and where I'd like to be. I find the programs that Angel develops for me to be extremely time efficient and the correct level of challenge to make substantial progress towards my goals.On the days that I come in to train, Angel and Jon are there to coach me on the exercises and to help me improve and maintain my form when I'm lifting heavy. They are both extremely personable coaches and are incredibly attentive to the small details of a correct technique. They consistently gauge how I'm feeling and make modifications to my training if necessary to get the most out of my workouts.The BUST facility is always kept clean and organized and the equipment is top notch. Definitely a minimalist feel to the place but all the equipment there serves a purpose. Plenty of parking available.read more
