Did a couple of Drop-ins at this gym. I’m usually pretty shy in trying new places. Especially even more when working out in front of new people. I ended up doing 2 of the crossfit open workouts here and EVERYONE was beyond warm and welcoming. The coaches were great communicators and teachers. Will be dropping in everytime I’m in town! Fully recommend!

One of the best gyms in the area. The coaches here truly want to see you succeed and reach your goals - whether that's weight loss, general health, or to compete as an athlete. The daily programming has a great mix of strength, gymnastics, and conditioning which the coaches also use themselves. 5 stars - keep doing what you're doing.

Started my CrossFit journey at CrossFit 617 and couldn’t me more grateful that I did. Their fundamentals course eased the learning curve of starting CrossFit. The coaches were very motivating, personable, and knew exactly what they were doing. Classes were tough and worth every second.

Jumped into Crossfit 617, and it's been a game-changer! They kickstart you with a must-have package: 3 personal sessions to master key moves, followed by 3 weeks of unlimited Crossfit magic. Their workouts? A brilliant mix of warm-ups, weightlifting, and non-stop cardio-strength combos. Plus, with daily diverse routines on their Zen Planner app, monotony is a myth. The vibe? A supportive crew cheering you on. Got a competitive streak? Check your progress against others on SugarWOD app. Yes, it's a premium spot at $200/month, but every penny's worth those 5/5 stars!

I dropped in for the week of Thanksgiving and the folks here were very helpful and welcoming. The facility is state of the art (I wish my box was this sleek!!). Will definitely be back if I’m ever in the area.

I’ve doubled my endurance and weight I can lift since starting here two years ago. Great community.

Awesome CrossFit gym! Great coaches, people, and facility. Highly recommend.

If you're trying to choose a CF gym in Boston, 617 is the place to go! They are so inclusive and vibes are great! Definitely makes it feel like everyone belongs there regardless of ability.

Cannot vouch for CrossFit 617 enough! I was visiting Boston from Puerto Rico for about a month and a half and needed a box to train at, and am so glad I chose this one. The coaches are incredibly professional and knowledgable, and the gym has an incredible community and vibe to it. Not the mention the programming is also fantastic. I'll absolutely be back when I'm in the Boston area.

Best gym in the Boston area. Extremely welcoming environment. Exceptional coaching staff. I would recommend this place to anyone that wants to improve and hit their goals.

Amazing gym! We were members here for a couple of months, but ended up moving out of state and away. We LOVED our time at CF617. The community is warm and welcoming, and the facility is top notch. I will definitely be coming back to visit.

When I moved to Boston I was very particular about the type of CrossFit gym that I wanted to join and so I spent a lot of time testing various boxes around the area. After my first drop in class on a Saturday morning at 617 Dorchester I was sold. The team and coaches here are incredibly welcoming and knowledgeable and work with each individual to make sure they’re comfortable and challenged. The community is supportive and helpful whether you’re brand new to CrossFit or have done it for years. I feel so lucky to have found 617 and highly recommend this gym to anyone!

The coaching here is the best I’ve ever had since beginning Crossfit 9 years ago, and the facility is beautiful and clean (the photos on this page show the old location. See the website for the new one)

Great local box! Professional, experienced, knowledgeable, and welcoming coaches with a supportive community that motivated me to achieve my training goals and have fun along the way. There is a plethora of equipment, a nice men's locker room space, and even an in house physical therapy studio. Excellent place to start or continue your fitness journey!

Didn't know what to expect but now I am hooked. Hands down one the best workouts I have ever had. A new refreshing way to workout the body and mind. Five stars from the facility to the educated staff and everything in between.

The owners and coaches have created a true community. One built around health, fitness, and encouragement. The new location is great and you even get to run next to the neponset sometimes.

Love everything about this gym! Both the coaches and the members genuinely want you to succeed and help you push yourself to work harder and be better in every workout. Very supportive environment where everyone is welcome! :)

Joining CF617 was honestly one of the best fitness decisions I've ever made and I totally recommend it to everyone even remotely interested in fitness. I know CrossFit can seem intimidating, but trust me, you can do it. And every day will get easier, because every day you'll get stronger. The coaches there are awesome and really want to see you succeed. Do yourself a favor and get on board at CF617.

I dropped in at CrossFit 617 - Dorchester for a week during the Christmas holidays and I am so glad I did. This is a brand new facility with amazing coaches and a superb owner/coach, Pete. I highly recommend this box and look forward to coming back again soon! Thanks for everything!

I can't say enough about this gym! I hesitated to join a Crossfit for years having felt intimidated, overwhelmed and not in good enough shape to begin. Pete, his team, and every single coach and member are amazing and beyond encouraging. They've created the culture and community they deserve and genuinely want everyone to succeed.

CF617 has been a truly amazing experience! If you are looking for a diverse, inclusive community of fitness-minded people, this is your place, no matter what your current level of fitness is. To understand why CF617 is so much better and different than a 'gym", consider the well-known phenomenon of people making New Years' resolutions to get in shape. They join a gym in January and start off strong but most have quit by Spring. Why? They walk into a room with hundreds of pieces of equipment and have no idea where to start, or what to do every day. They fall into a routine of a bit of weight-lifting and then some cardio on a treadmill or bike. BORING. No coaching. No improvement. So they give up. It is TOTALLY different at CF 617. You show up for an hour 3-5 times a week for HIIT (High Intensity Interval Training). It is a structured class with an instructor. The instructor guides the class through a routine of warm up, stretching, technique, and then there is usually a strength piece followed by the WOD (workout of the day). Although each class follows the same general format, in 9 months every single class has been different. And every single class builds on the classes that have come before. In each class you may have CF veterans who have been doing it for years mixed in with brand new members. All of the workouts and exercises are "scalable" so that everyone can do them. And before you even start your first group class, everyone goes through Elements: a 1:1 introduction to CF. I am 61 years old, have run the Boston Marathon and played collegiate rugby. 9 months into CF and I am far stronger, fitter and more flexible than I have ever been in my life. The motto of CF617 is "Be Kind. Be Humble. Be Strong". The coaches and the community are incredibly supportive. YOU WILL LOVE IT!!!
