“As someone who has lifted for 10+ years at conventional gyms, I didn't know if a class-based routine was going to be for me. Wanting to switch things up, I attended a free class at D1 Training and I've been hooked ever since. Every aspect of D1 is top-tier. From the facility, equipment, coaches & staff, amazing community of people, and of course the kick-ass workouts - D1 is truly a premium product. D1 offers a professionally designed program that follows a lower, upper, full-body 3-day cycle, twice a week with the program overall changing every 8 weeks. While standard conventional lifts are still incorporated in every workout (squats, bench, deadlift, shoulder press, etc.), a strong focus is also placed on dynamic movements, stretching, accessory lifts, and exercises that I never would have done of my own. I’ve felt myself grow stronger, more flexible, and overall vastly more conditioned than I’ve felt in years. Also, because of the structure of the class, you get a great cardio workout as well, all without succumbing to the boring treadmill, stepper, or elliptical. But outside of the workouts, the thing that surprised me the most was how incredible and amazing the people are. There’s no BS or fluff behind all these reviews that rave about the community. For someone who goes to the morning classes before work, it honestly feels like a strong friend-group and is a perfect mesh of hard work, sweat, encouragement, and fun. Even the two owners, Vic & Cara, attend! If you're someone like me who has lifted for a while and want to try something new or if you're at the beginning of their fitness journey, please give D1 Training a shot. I promise you won't be disappointed and you'll leave each class feeling confident and proud of what you just accomplished - which is a great way to start or end your day. Special thank you and shout-out to Coach Ben, Coach Abby, Vic & Cara, Melanie, and of corse the 6AM crew!”

“My daily 6 AM D1 Training Adult Classes set my days for success! I joined D1 Training in Burlington MA trying out a free class in early May this year and then joined the 6 week challenge. I decided after the first week to try the 6AM class and just wow! There was no looking back. I started from going 3-4 times a week to 6 days a week. The feeling as my body starts to warm up is gratifying, and the feeling at the end of a hard workout each day is inexplicably satisfying. These early morning workout sessions super charge my day—They settle my mind, and I feel more organized and productive throughout the rest of each day.

All the coaches are supportive, knowledgeable and thoughtful in their approach making sure we all do the exercises correctly. They carefully monitor our progress through each routine, and are always on hand to provide suggestions for modifications to prevent injury. They all have exceptional educational backgrounds and working knowledge in exercise training and nutrition. The coaches and nutritionists provide sustainable nutritional suggestions —fruit, vegetables and protein choices— which also significantly increased my energy level.

Intriguingly, since I generally like to work out alone, I was really surprised that I enjoyed the group setting at D1 Training so much. The setting here feels very different from other sports clubs. There is a true sense of community support. Everyone is encouraging without being intrusive. There is laughter, and camaraderie in shared gratified feelings of accomplishment having completed a hard workout at the end of each session. It’s quite a wonderful and unique experience.

Now 10 weeks in, and after 2 weeks on vacation during which I continued to follow a vacation workout the coaches at D1 designed for me, I can really start to visibly see that I am stronger, gained more muscle, am more toned overall; have increased flexibility and feel less aches in my joints. I feel healthier and more energetic now than I’ve felt in the last 15 years.

I’ve tried various high cardio exercise regimen and restrictive diets over the years with very little success. D1 Training is teaching me to take better care of my body, to embrace a complete workout with more balanced core and strength training and good nutrition—giving me the tools to achieve a more sustainable healthy lifestyle and roadmap for the rest of my life.

My thanks to Vic the owner and the coaches at D1 Training for working with me, supporting my efforts to achieve my goals.

I can’t wait to see where this journey takes me!”

“I’ve been a member of D1 since January. D1 has become my safe haven and home! I never feel like I’m there just to exercise. D1 makes me challenge myself mentally and physically each and every time I show up to class. The coaches are amazing and really push you, and keep you motivated. I go to the 6am class and I feel I’m part of a fitness family!! I will always be grateful for D1 and all the growth I’ve done in 2023 because of this amazing place! If you haven’t started yet and are thinking of a place to go this place for you!!! <3 Kristen!”

Kristen B.

“If you are looking for a fun and supportive community, this is the place! D1 team is very open, welcoming and they will push you!

Music during workouts is always on point!

Compared to other places I’ve been to, D1 doesn’t create a competitive or judgmental environment. You are there to improve yourself and you work at your own pace. After my 6 week challenge I decided to join and I’m happy with my decision!”

Lidia G.

“D1 training facility is by far the best gym/training facility I've had the pleasure of going to. I joined back in March and have had nothing but a positive experience here. The staff coaches are absolutely amazing, especially Justin. The minute you walk in you feel welcomed, and it has such a positive and motivating environment. The staff is helping me stay on track and reach my fitness goals. They offer group classes, 1-1, open gym, kid classes, etc. I highly recommend anyone to give this facility a try. You definitely won't regret it!”

Jose V.

“The best gym I have ever been to!!! The atmosphere here is incredible and the staff are all helpful and welcoming. Consistent workouts here will without a doubt get you the results you have been looking for. Not to mention you will meet other individuals who are working towards the same goals as yourself and will encourage you along the way!”

Devin S.

“I am so happy I saw the ad on Facebook for D1 Training. I tried a few gyms and classes and this is the only that I stuck to.

I used to do a lot of sports. But then I started working, had kids and never had time for anything. It has been 15+ years since I properly exercised. I became a blob but I found it impossible to motivate myself to do any exercise. I knew I needed something else to motivate me and keep me interested. Then I went to a free trial class at D1 Training Burlington in response to an ad and have been a member ever since. The program at D1 is a perfect solution for me – the classes they are structured as kind of circuit training with 3 areas of focus: performance, strength and core in each class. Every class is different so you never get bored, the classes are high energy with great instructions and you very quickly see results which keeps me motivated. By default of this being a group class, we all push each other to work hard and time goes by very quickly.

After just 2 months, I feel stronger and fitter than I was in 15 years and I am addicted. I highly recommend D1 Training.”

Michaela D.

“I have been trying to get back in shape for a few years. Other gyms I would go for a couple weeks and then stop going because it’s either always busy or I can never find the right routine. After 5 weeks at D1, I have managed to keep my routine and have fun going to the gym. The classes are very challenging but rewarding and that’s what I have been looking for. Also, class sizes are smaller so you are able to perform the exercises without having to worry about others slowing you down.”

Dustin L.

“My kids love working out at D1. It’s been an amazing experience! Also a sincere thank you to the staff at D1, especially Coach Melanie for all their hard work in creating the workouts and recruitment video for my daughter. It was a huge help during the application and recruitment process. I can’t thank them enough.”

Amanda L.

“My daughter has been doing sessions with Melanie and they are great! She enjoys them and has gotten so much better with her motivation to work out and train. I highly recommend. My older daughter will be starting sessions there as well.”

Jennifer J.

“I joined D1 based on the recommendations of a fellow suburban dad, and I am so happy that I did. The entire team somehow makes intense workouts really enjoyable and very gratifying... not sure how they do it! The programs are excellent and the trainers are motivating, challenging but keep it fun. Abby, Ben, Devin and Justin make 6am workouts fly by and manage classes with people of all different goals and fitness levels but connect with everyone. Beautiful facility that is kept in immaculate condition. This is a great team to work with - no attitude or arrogance. Highly recommended (and thanks to the team for getting this suburban dad back to working hard!)”

“I recently completed an introductory fitness challenge at D1 where the staff is absolutely amazing! From the very first day, I felt welcomed and supported by the trainers who were knowledgeable, attentive, and motivating. As someone whose metabolism is changing, it was time to change my habits; this workout offered the perfect balance I was seeking.

The environment is incredibly supportive and the music is always pumping, creating a fun and energetic atmosphere. The class size is just right, allowing for personalized attention from the trainers while still being able to interact with other members.

One of the great things about being at D1 is that you never have to worry about what other people are thinking - you won't even have time! The focus is solely on oneself and your own fitness journey. The trainers are always available to answer questions and provide guidance, ensuring that you are getting the most out of each workout.

Overall, I highly recommend D1 to anyone looking to make positive changes in their health and fitness. The staff is top-notch, the environment is supportive and motivating, and the results speak for themselves. Don't hesitate to give it a try - you won't regret it!”

“Had my first class yesterday. Met with Vic the owner who is such a great guy and Justin ran an awesome class… and I am feeling it today! The facility is awesome and the class was great. Signed up for the membership immediately and really excited to get going.”

Rich K.

“I started D1 because I needed a life change. I joined the 12 week challenge and started working out with Ben. It was hard, but he made it doable! I’m now doing the classes, and have more confidence than ever. I can’t say enough how happy I am with my D1 experience so far!”

“D1 Training: Exceptional Fitness

As a member of D1 Training, I cannot speak highly enough about the exceptional fitness center that it is. From the moment you walk in, you're greeted with a warm welcome and a contagious energy that motivates you to push yourself to the limit. The trainers are simply fantastic, and their passion for fitness is evident in the way they lead every session.

One thing that sets D1 Training apart from other fitness centers is the variety of training sessions offered. Whether you're an early bird or a night owl, D1 Training has a time slot that fits your schedule. The daily sessions at 5:30 am, 6:30 am, 9:30 am, 6 pm, and 7:15 pm make it easy for everyone to find a time that works for them.

Not only does D1 Training cater to adults, but they also have training sessions for children and youth athletes. As a parent, it's important to me that my children are active and healthy, and the trainers at D1 Training are incredibly welcoming and encouraging of young people. The facilities are also very clean, making it a safe and healthy environment for everyone to work out in.

The green turf that is reminiscent of a football field is just one of the many features that make D1 Training unique. It's a refreshing change from the standard gym floor and adds an extra element of excitement to every training session.

Overall, I highly recommend D1 Training to anyone looking for a fitness center that truly cares about their members. The trainers are knowledgeable, friendly, and passionate about helping you reach your fitness goals. The energy and motivation you'll find here are unparalleled, making it an experience that you won't find anywhere else.”

Shiv R.

“D1 is the perfect gym no matter where you are in your workout journey. I played sports in high school and am in the military but got out of shape the last few years. Within 6 weeks I saw changes and built stamina! We did weight lifting, cardio, stretching, and performance exercises but it truly is at your own pace. I recommend trying the classes to anyone and meet all the trainers, they all have their benefits and unique styles! Overall great gym and staff!”

Kinn

“I joined D1 from an Instagram ad and wasn’t sure what to expect. Now, after 6 weeks, I can confidently I am SO happy I decided to join!! The community is truly friendly, fun and help keep me accountable. I look forward to getting up at dawn to show up to my workouts. It’s so awesome to have engaged coaches who run you through the workout while challenging and encouraging me to level up. I leave every session feeling more powerful and strong, and soo happy to be part of this group. As a bonus— I am seeing and feeling some of the best physical results in my body ever! Highly recommend this place to new and experienced athletes :)”

Katherine M.

“I started bringing my 11 year old son last October as a trial to see what D1 was all about and if they could help with my son’s running mechanics. Within a couple of months of attending, I noticed that my son had become more explosive off the line, his lateral movement and change of direction had improved more than my expectations. Most importantly, his athletic confidence has increased and he now appreciates and has recognition of hard work paying off. All of the coaches (Ben, Justin and Garrett) are very knowledgeable in their craft and great interacting with the kids. At the very least it is a great workout for the kids, the kids build a competitive spirit, they will burn energy, build body mechanics maturity, stamina and strength all while having fun and gaining confidence in the meantime. It’s worth giving it a shot and Emily, Melanie and Vic are great to discuss options for what works for your household! I would strongly recommend checking D1 in Burlington out!”

Shaun K.

“Love the program that D1 has to offer. The understanding of fitness strength and community has a very good balance within the class, whether you are a beginner, and an athlete that is in shape or getting back into shape.

They make you feel accomplished and able with the program. The support and accountability piece also has been a huge part of my success so far.

I have enjoyed the program so much that I have recommended to my athletes whom I coach This program as one that will be perfect for a strength and conditioning session.”

Danielle A.

“I can’t say enough good things about D1! Top to bottom my experience has been nothing but amazing.

Every trainer at D1 is super friendly, super helpful, and awesome at making every class feel new and exciting.

The classes themselves are difficult for sure, but get easier by the day. I expected to be very intimidated by the workouts and the class setting but once I settled in I found there was nothing to worry about at all. I learned a ton about different kinds of lifts and exercises and I feel totally different physically and mentally than how I felt going into this.

If you’re on the fence about signing up for any reason at all, I strongly recommend you try it out for yourself. You’ll be hooked before you know it and you won't regret a second of it!”

Collin G.

“Love it there feels like a team to help you get to your goals. Been there 6 weeks and absolutely seeing results.”

Steve M.

“I am Burlington resident and happen to come across D1 a phone conversation with Melanie (GM) which encourage me to step in D1 Burlington Studio
My perception of Gym and Physical training completely changed
I saw these words on the wall
: Respect | Determination | Dedication | Fearless | Confidence | Responsibility | Integrity | Perseverance | Self-Discipline ¡ Accountability | Honor | Selfless
And believe me when I say this owner Vic, Coach Ben and Garret actually practice these words to the core
They are here to help you build confidence, make you feel great, monitor your food intake , yet very result oriented
I lost 6lbs in just a month
I would HIGHLY RECOMMEND D1 to everyone who would like to get back in life happy and healthy
My family is very proud of me and thankful to D1 helping me reach my goal”

Sameen N.

“I joined D1 in November as part of the 6 week transformation program. I was looking for a fitness experience in a group setting with classes that would make 60 mins go quickly. I found it in D1! The coaches are amazing, the people are fun and encouraging, and the exercises are challenging but doable. I come from a yoga and running background, so everything was quite new to me, but I always feel safe and well instructed.”

Karen R.

“

I started D1 Training about 3 months ago and have enjoyed every minute. The coaches and staff have helped me find the motivation to get back into shape and prepare for the upcoming soccer season. The atmosphere is fun and motivating. Group trainings are great for both athletes and adults simply looking to improve overall health. I’ve been genuinely impressed with the coaches and their ability to cater to everyone’s specific goals and/or limitations. I’m someone that’s become bored with traditional-style gyms and cardio-heavy classes. If you’re like me, give this place a try!

”

Nick N.

“Every time at D1, I walked out satisfied! The morning workout really wakes you up. It is better than coffee to help you segue into schools or works! I have been more active and having a better mood. The membership discount on the one-to-one session really help me save some money and get in shape for the summer. Strongly recommended!!!”

Justin C.

“

You will find a well stocked fitness facility that offers small group training with a focus on athletic performance. If you are the type of person that does well with a structured program and likes accountability, you should give D1 a try! Workout group sizes varied from 4-15 so everyone gets attention and assistance if needed. Coaches and staff are beyond friendly and always willing to help you achieve your next goal. Parking is easy and they have showers too.

Jayden S.

“I started D1 6 weeks ago and I can honestly say this is one of the best gyms I’ve joined. I became very inactive due to the pandemic and once restrictions were lifted I had a difficult time motivating myself and holding myself accountable to meet my fitness goals. Fortunately the coaches and staff at D1 helped me find the motivation to get back in shape. All of the couches are great and the classes are challenging and fun at the same time. The other members are always there to cheer you on during class which makes the whole thing feel like a community. I recommend anyone looking to join a new gym to check D1 out. You will not be disappointed.”

Jason K.

“Joining D1 has become a critical part of my daily routine in 2022. From the moment I walked through the doors, I was greeted with a warm and welcoming atmosphere. The staff is incredibly friendly and knowledgeable, and they have gone above and beyond to make me feel like part of the community. But what really sets this gym apart is the level of personal attention and support that the coaches provide. The coaches are extremely encouraging and I actually look forward to 5am workouts now, where I thought I would never say that.”
