My happy place! 🥰 I started coming to Jayfit and working with Justin and Chrissy in September of 2024. After losing 80 plus pounds on my own, I needed to put on some muscle and Jay has helped me and continues to help me achieve my goals and pushes me to keep going! I never woke up excited to work out until I came here. Lifting and strength training has changed my life and I’m learning so much along the way! I am the in the best and strongest shape of my life at 48 years old. The best investment was the one I made for myself and my health and fitness. I feel amazing! Justin’s process is very thorough and he checks in regarding any prior injuries and gives helpful feedback to adjust your positioning so that you complete the exercises safely. Even during group sessions he does a great job of making sure everyone is attended to and supported so that we all meet our personalized JayFit workout goals for the day. I highly recommend you book a session with JayFit - your body will thank you for it!

Having a baby changed everything about my body including my self confidence. I met Justin for an assessment about three and a half months ago and I have been going consistently. Since, I’ve never felt better and I have my body back! I love training at JayFit Training Studio and I love the people who attend sessions. Everyone is friendly and hearing their transformation stories only pushes me for more. I am very grateful to have met Justin and have someone like him in my circle.

As you get older every day you wake up and something else hurts! Not anymore! Thanks to Justin, I have reduced or eliminated body inflammation and chronic pain from natural degeneration and/or prior injuries. He continually works to create a custom workout plan to support both your strengths and to protect and rehab where needed. It is great atmosphere to train - easy and supportive!

Jay is thoughtful and experienced. I joined his gym following back surgery for a herniated disc and Jay tailored a specific program to help me improve both strength and mobility.

Wonderful boutique style personal training gym. I've had a lovely experience training with both Justin and Chrissy. The sessions are in an intimate setting and personalized to your needs. Everyone has their own custom routines established for their own goals. They are very accommodating and great trainers who truly care. They do a great job of creating a nice environment. They even have a suite for one on one assisted stretching, shout out to Af! Take it from someone who hates the gym, I love coming here. Good availability and parking lot is a plus. Thank you JayFit, highly recommend!

Got Questions? We've Got Answers Right Here!

It all starts with a free Starting Point Session. This is where we learn about your goals, your lifestyle, and any challenges you’re facing. If we are a good fit, we design a personalized program that fits your needs and get you started towards achieving your goals.

Most clients start to feel better within the first few weeks. More energy, better movement, and improved confidence. Visible changes typically appear based upon consistency and commitment over time. At JayFit, we focus on building results that last, not just short-term changes.

We offer practical, sustainable guidance on nutrition, recovery, and lifestyle habits to support your training. Whether it’s meal selection, sleep habits, or stress management, we help you build routines that fuel real progress — without extreme diets or burnout.

Not at all. JayFit is built for real people at all fitness levels — whether you’re just starting out, getting back into a routine, or already active and looking to level up. Every program is personalized to meet you where you are, and our coaches guide you through every step so you feel confident and supported from day one.

JayFit isn’t just another gym. We’re a semi-private personal training facility built around coaching, community, and real results. Every session is personalized for your body and your goals, guided by educated and experienced coaches who actually know your name. You won’t find crowds, guesswork, or cookie-cutter workouts here. Just a supportive environment designed to help you feel better, move better, and live stronger.

Most JayFit members train 2 to 3 times per week, depending on their goals, schedule, and starting point. We’ll help you choose the right frequency during your Starting Point Session and build a routine that fits your life. Whether you’re looking to get stronger, lose fat, or simply feel better day to day.

It all starts with your Starting Point Session, where we get to know your goals, lifestyle, and movement needs. From there, we create a personalized training plan just for you. You’ll train in a semi-private setting (Maximum of 4 clients per session) led by a certified coach to guide and support you every step of the way. Every workout is planned in advance, progress is tracked, and we adjust your program as you improve, so you’re always moving forward.

Every JayFit session lasts about one hour and is coach-led, personalized, and results-focused. You’ll train in a small group setting (up to 4 clients), but your workout is tailored specifically to your goals. Sessions typically include a warm-up, strength training, and conditioning, all designed to help you move better, feel stronger, and stay injury-free. You’ll get expert guidance, encouragement, and support throughout.
