"Alright, no more gatekeeping! Despite being new to the area for just two months, this fitness center has quickly established a vibrant and growing community. I’ve taken several group classes at JustTone Fitness, and every single session has been a wonderful experience. I came in with little prior fitness history, but Justin, the trainer, is very attentive and knowledgeable, guiding and supporting me at a level where I can push myself effectively. There’s different training each day of the week, and every class is unique, presenting tough challenges that are always rewarding the next day. The atmosphere has also been very welcoming and motivating, making the workouts an exciting achievement rather than a chore. As I feel myself steadily getting stronger and more energized throughout the week, I highly recommend checking out JustTone Fitness as your next productive routine!"

"My first time training at a private gym! The gym is new, clean, and spacious. They have a great selection of equipment, and I love that there's parking. The vibe is so uplifting and motivational. I've been training with Justin for three months now, and I love his enthusiasm and how effective his workouts have been in helping me reach my fitness goals! They also offer group classes here. Thank you, Justin!"

"I’ve been training with Justin at Just Tone Fitness for a few months now, and the experience has been nothing short of amazing! Justin is not only incredibly knowledgeable about fitness and nutrition, but he also tailors every workout to my specific goals and needs. His positive energy and passion for what he does are contagious, making each session something I genuinely look forward to. What sets Justin apart is his ability to push me beyond my limits while keeping it fun and engaging. He explains every exercise clearly, ensuring I understand the technique and get the most out of my workout. I've seen significant improvements in my strength, endurance, and overall fitness, and I couldn’t be happier with the results! If you're looking for a trainer who is dedicated, motivating, and truly invested in helping you achieve your fitness goals, Justin at Just Tone Fitness is the one to go to. Highly recommend!"

"I’ve taken group fitness classes like Barry’s for the last couple years and JustTone Fitness is something I’ve been needing for so long! I took my first class with Toni and he was wonderful to work with. He’s focused on strength training and within the 50 minute class I got so much advice and feedback on my form. Not to mention I left accomplished coming out of class. The classes are 12 max which is great if you’d like to get some personal time with the instructors. They’re also big about building community within the gym which I love. Looking forward to more classes here and the milestones I’ll achieve here!"

"I signed up for the unlimited monthly program, and the value is incredible. I have been struggling to stay motivated working out alone, but with the coaches, Toni and Justin, there is great accountability, energy, and rejuvenation. They have an immense list of exercises and everyday feels like a whole new gym session! Working out alongside other members also fosters a healthy level of competiness and camaraderie. I will be signing up again for month 2!"

"I've been going to JustTone for 3 months now and have been loving it. I've take lots of Barry's, F45, and other classes but this has been the one that I've decided to go to regularly. When I initially started going to JustTone, I had some knee pain and in the 3 months, it has greatly improved. The instructors are easy to chat with and the equipment is new. Toni happened to be my trainer at Equinox and was surprised to see him when I took my first class here. The sessions focus on proper form and strength training, which has made a noticeable difference in my overall fitness. Highly recommend!"

"It's just so much fun here!! Justin offers every piece of fun equipment I can imagine here, from medicine balls, to all the squat racks and power racks - and all the fun stuff that I can't name yet. They really have a spotless, state-of-the-art gym setup and never make people feel bored. 🤩 And thank you for creating such a supporting and inclusive vibe here! I instantly feel included as a team accomplishing a goal together."

"Loving this new fitness gym in the neighborhood! I usually get intimidated by commercial gyms since I’m not exactly sure what exercises to do, but I’m glad JustTone offers group classes and personal training that’s led by either Justin or Toni. I’ve taken classes from both of them and both are great! They’re very enthusiastic and once I stepped into the gym, the intimidation of working out went away. They are very friendly and welcoming and are ready to work with my fitness goals and answer any questions I had. They’re also on ClassPass so I will definitely be frequenting this gym!"
