There are not enough "stars" available for a proper review! D and her entire dFit crew have created a community - more like a "home" - a comfortable place to be yourself, work hard and be in a safe, attentive environment. From the work out options to the nutritional programs and guidance, you will find top notch professionals at every level that are ready each and every day to make you stronger and healthier.
Thank you dFit!

I really wanted to like D*Fit. I loved that they had outdoor classes during COVID.

But their spin classes are really lacking. The bikes dont have any kind of tracking on them so you cant track RPM, watts, or any of the normal metrics that make a spin class work, and let the instructor calibrate your efforts. That said, it didnt matter much - the instructor didnt have a mic, so she had to shout at us. She kept losing her breath doing it, and couldnt choke out more than a few words.

I emailed the gym asking about all this, and got a snarky reply back that I clearly had some very specific needs

Almost nine years ago, I walked into the ultra beautiful space at D*FIT and began a life changing journey that becomes increasingly important for my physical and mental health. I began instructing barre just over 7 years ago and remain a student at the many amazing classes offered. From spin, to yoga to TRX, D*FIT has it all. The team of trainers is highly skilled, creative and dedicated! I feel compelled to write this review now as I am so impressed with the response made to our current reality of staying home. D*FIT quickly adapted and moved to a virtual platform that includes live classes and

DFit is an awesome place to plan a whole fitness program. Their spin studio is excellent and provides a great atmosphere to work out. They also provide tremendous support to the county youth cycling team!

I love this place! I considered myself an active but only 50-60% in-shape human. My goal when coming here was to maybe lose a pound or two but to ultimately learn about building muscle without becoming super bulky. They have a nice variety of classes that really let you focus on the personal goals you have. The staff is always willing to educate and help. I already feel stronger after taking a few classes. The staff is hands on and the atmosphere at their classes is welcoming. I've been to fitness studios before that felt super cliquey and not too kind- DFIT's atmosphere is friendly which

I've been coming to DFIT for about two years now and I still have the utmost respect for all the amazing trainers, friendliest employees and the
incredible Daniela, owner and sought after trainer herself. Not only do ALL the employees greet you by your first name always, but you feel like a family when there. Everyone is happy and the energy is infectious. Not to mention the workouts are killer! They have all the best equipment and diverse training and classes. DFIT supersedes any gym around!!!!!

Love love love this gym! Just had another massage with Serena and it was beyond awesome! When you enter the massage room it is like being in a cocoon - spacious, dark, soothing and perfect to relax. The massage was one of the best I ever had and really addressed my problem points. I felt wonderful when I left! Hidden gem. Try it out. Can't wait to go back!

So I found this place by chance when I was looking for a different kind of gym online. It's right by my apartment, so I decided to drop by and check it out after work. I was greeted at the door by a guy named Justin who I could tell from the start was a good guy. He showed me around and introduced me to some other staff members who were just as cool. I have to say that I was very impressed with how friendly everyone was and the whole vibe of the studio. Completely on impulse, I decided to run home, change clothes and come back for the 7pm Fit circuit class with Lou (who also was a really cool

I love this place! Great location, classes, instructors, nice facility, you can't go wrong! I love the D*Bar too, fantastic smoothies. My only criticism is that I wish they had more evening classes (currently they only have 1 at nite Mon-Thur) Since I commute early into NYC it's hard for me to attend their early sessions.

This is the best gym I've ever belonged to and I've been to A LOT of gyms over the years. If you're accustomed to showing up at the gym whenever you like and jumping on a machine, then this format takes getting used to because that's not how it works here. You can only choose from group training classes and personal training sessions that are by appointment/reservation. I actually like this format a lot because it fosters a sense of community among staff and members and it's made me more consistent with my workouts. The entire staff is warm and welcoming and so supportive
