  Been coming to J+K fitness for about 6 months. Great staff. Trainers are motivating yet not overly pushy. I was hesitant to do personal training initially but now feel like it ended up being a great investment. Would definitely recommend the place to my friends.

  I have been working out with Jae for almost two years, and have been training with Griffin over the past few months as well. I’m 46 and in good shape, but I have had fairly chronic back pain off and on from an old injury that has required four back surgeries over the years, including a final spinal fusion at L4-L5 several years ago. My lower back and hips were still always tight, I would have consistent flare-ups of lower back pain, and I was seeing a chiropractor on a semi-regular basis. I went to Jae’s studio with the goal of being able to work out consistently, build some muscle, and get better abs, all while taking care of my back. Jae focused on getting me set up with a great series of warmup/stretching/core exercises that I eventually started doing on my own at home before our sessions (and on off days). During our sessions he focuses on compound movement exercises that include a lot of join mobility/flexibility and accessory muscle groups to improve deep core strength and help prevent any back issues. He always keeps things interesting and different at our sessions with new exercises and stretches thrown in each time. I will occasionally still tweak my lower back a bit by doing something I shouldn’t (moving something awkward and heavy, overdoing it on a run trying to sweat out a bit of a hangover), and Jae can pinpoint what’s going on and switch up our session in real time to focus on exercises that both stretch and work the muscles that need it, as well as spend a few minutes at the beginning or end of our session focusing on purely stretching if I need it. Between the at-home warmup/stretching exercises he’s given me, plus my regular sessions at the studio, I completely stopped needing to see my chiropractor after a few months, and my back has been great. I would HIGHLY recommend Jae’s studio to anyone, back problems or not. Jae and his other trainers work very closely together with clients, and whether I’m training with Jae or Griffin they know my full history, as well as what the other has focused on with me in prior sessions, and tailor things appropriately. And I have abs at 46 while still drinking a little too much wine from time to time!

  I was hesitant to get back into the gym and start training with some real professionals but Jae of J+K is great to work with. His staff is friendly and knowledgeable and are there for YOU, not themselves. The gym space itself is fairly large with two individual spaces so even when other members are being trained or working out on their own, you never feel crowded or disturbed while concentrating on your personal fitness goals. I had back surgery in 2007 and have been worried about getting back to the gym for fear of hurting myself even further. Jae totally helped me strengthen my core muscles with resistance training and kept me on track. Slowly but surely my sciatica pains went away and now I feel comfortable working out on my own knowing the correct form to use when lifting. My goals are still a work in progress but with Jae's help I have gained muscle, lost fat, and feel a lot more comfortable about myself than ever before. I went from 15% body fat down to 10.5% and I will now take my shirt off when I go to the beach!

  So a gym with bodybuilders . . . sounds a bit daunting. That's what I thought too! It's not, it's a friendly local neighborhood gym. It's one of the cleanest j+k fitness studio I've been in. Parking is decent and there's plenty of street parking. I use free weights and the machines, the weight room is usually crowded. The machines are the updated and adequate for what I need. There's an area for stretching which is nice. Classes are good but some you'll have to pay extra for. Prices are a bit higher than the other surrounding gyms. Overall, I'm happy when I go here.

  The moment I walked into J+K Studio, I felt comfortable. The studio is well kept and offers an intimate feel while training. There was never more than one other client training during any of my sessions; which allowed me to focus on my time with my trainer, and not be distracted by others in the studio. I primarily trained with Sean and Natalie, and have nothing but great things to say about the both of them! At my first session, I could sense that they wanted to understand my initial abilities and limits so that my subsequent sessions would be safe and challenging. Whether I was training with Sean or Natalie, they were extremely professional, energetic, focused on me, and were invested in seeing that I had the right tools, training and support in working towards my fitness goals. I especially liked that Sean and Natalie took the time to explain the reasons why I was doing a certain exercise, which muscle groups they worked, how to properly perform the movements to limit the possibility of injury. Hands down, Sean and Natalie have been the best trainers I've worked with! Sean's energy in every session made training fun and pumped me up to push myself. If you're on the fence of about training at J+K Studio, do yourself a favor and stop by to meet Jae, Natalie and Sean! You'll immediately feel the energy of the studio, and see how awesome the three of them are. They truly take the time to get to know you, they're invested in your fitness goals and make every session fun and challenging!
