Fantastic. I’ve been a member of this gym for nearly 10 years, and I can honestly say it’s one of the best decisions I’ve made for my health, routine, and keeping up with my kids. The coaching staff is knowledgeable, supportive, and genuinely invested in helping members reach their goals. They meet you where you are and push you in the right way, whether you're new to working out or have been training for years.
What really sets this gym apart is the environment the people have set up, it's welcoming and comfortable. It’s a place where you feel encouraged, not judged, and the community atmosphere makes it easy to stay motivated. After a decade here, I can confidently say this gym has played a major role in my fitness journey, and I highly recommend it to anyone looking for a reliable, supportive place to train.

I joined TJ's about 6 months ago shortly after moving to the area. It has been a great experience. The coaches do a fantastic job pushing you and teaching proper form. The members are also super welcoming and encouraging. In just 6 months, I have noticed a huge improvement in my fitness and have met some awesome people. Have even enjoyed a few beers after the Friday afternoon classes with other members. Highly recommend joining if you're looking for a new gym or just starting on your fitness journey!

I've been a member since 2021 and looking back, it's amazing to witness firsthand the transformation on your health and fitness.
At TJ's, you'll also grow your community. It's like a social club where everyone is in workout clothes. Love those Friday apres-workout gatherings.
You'll brush up on your social skills, making friends between sets and bonding over protein shakes.
As you push yourself physically, you'll also be boosting your mental health and confidence. It's like sweated therapy.
So, if you want a gym that'll help you grow in multiple ways, TJ's is the place. Come for the fitness, stay for the friendships, and walk out every day feeling like a whole new person.

I don’t know if 5 stars is enough to rate how much I love and value TJ’s Gym! Been a member nearly 13 yrs and hooked from day one. Tried many different workout methods prior to TJs and none really felt like my thing. Starting pretty late with Crossfit (not currently CrossFit gym but very similar methodology) I wasn’t sure how I could do most things as i just wasn’t that fit. TJ changed that mindset! His encouragement of me personally and his coaching, along with our other amazing coaches, has made me feel like a true athlete. I’m far from young but can say I am as fit or more fit than I have ever been. And… one of the absolute game changers for me is the camaraderie with my fellow gym peeps! I look forward to working out my 4-5 days a week with my people and would not have been as successful in improving my fitness for longevity without this incredible community TJ has built and fostered! Love

TJ’s Gym has exceeded my expectations in every way and has been life-changing since I joined a year ago. I came to TJ‘s frustrated and bored after many years working out at home and making little progress.
I started doing personal training sessions with Dana, an amazing trainer and a delightful person, and I could not enjoy our sessions more. I’ve gotten noticeably stronger and working with her gave me the confidence to go to the fitness classes. They are super challenging (but easily modifiable if needed) and I love how the small (clean!) space and thoughtful programming easily accommodates everyone’s fitness levels. I am still blown away by the friendliness and supportive environment from both the coaches and the members.
If you’re struggling with fitness or body image issues, limited mobility or injuries, or just think you’re an introvert who actually likes working out alone, joining TJ’s Gym can transform all of that. At 53, it is no small thing to feel healthy and strong, make new friends and feel like you are part of a wonderful community.

I’ve been a member of TJs gym for 3.5 years. When I joined, I had adopted a lifestyle of focusing exclusively on work and family, and needed to focus on prioritizing my own physical health.

I’ve been a member of a lot of gyms, and if you are looking for something that “sticks” I would look here first.

Interacting with TJ is delightful. He is genuine, passionate, and generous. Before deciding to join his gym, we spoke, and he gave me his undivided attention for close to an hour, eloquently explaining the importance of fitness and fielding my questions patiently.

I have received personal training sessions from Head Coach and Programmer, Nick LaPlant, who is smart and dedicated.

I’ve seen an incredible change in my day to day life as I’ve built strength and confidence.

TJ’s Gym embraces the concept of healthy bodies. While there are plenty of muscles around, the clientele ranges in age from teenagers, to octogenarians. There is everything from doing it yourself too, one-on-one training, group workouts, etc. you can get involved in whatever level works for you. The employees all have a can do it attitude and encourage clientele to push for their best selves. I have been working out with TJ over the past year plus and have had nothing but a great experience. He has embraced my limitations and pushed me to work harder and smarter. The best days of those when I finish the workout and am utterly exhausted. If you’re more of a do it in a group type, there is ample direction to make sure you know what you’re supposed to be doing and in what order. There are also enough devices to use for cardio and weights without having to weight line to use something. There is no “scene“ at this gym and nobody is showing off. People are here to get in shape and do the work.

I recently joined the small group training class. The format feels like it was built around me: small, focused sessions that are equal parts communal, fun, and challenging. It keeps me accountable in a way nothing else has.

Best gym and community! I’ve been coming here for just about two years now, and honestly, it’s my favorite place to work out and hang out with all the members. Everyone who comes here is super nice and encouraging.

Since joining, I’ve made great new friends and always look forward to seeing them in class.

Aside from how much I enjoy everyone’s company at TJ’s, the trainers are top notch, and the workouts are fun and offer a great balance of cardio and strength. You can come here 5 to 6 times a week without feeling like you’re repeating the same things or overdoing it in one area, which is great because you get a lot of bang for your buck and it keeps you motivated.

I’ll wrap this up by saying that half the reason I like living in this area is TJ’s.

Thanks for creating such a unique gym experience, and shoutout to all the members for being so kind and welcoming!

My husband and I have been going to TJ's small group training now for a couple months, 2-3 days a week. I can't believe what a difference it has made! I already had a regular yoga practice but my doctor, all the media out there, etc. kept telling me I needed to start weight training. I was not at the level to go to the group classes, there are so many different machines, weights, etc, and I don't know proper form so we signed up for small group training, hoping to graduate to the larger group after a few months. I love the size of the small group, I know if I'm doing something wrong I'll be corrected. Its fun to push through the exercises together, everyone supports one another. And its HARD. But good hard. Going with my husband has been totally bonding for us as well. On top of all that, I have already had two separate occasions where random people came up to me and said I looked really toned! That has never happened. I couldn't recommend the program or the coaches more.

Feels like a neighborhood pub—with barbells.

TJ’s Gym and Social Club is one of those rare places that gets the formula just right: expert coaching, a genuinely welcoming community, and a culture built around helping you do your personal best.

The trainers are serious professionals—knowledgeable, attentive, and focused on good form and smart progress. You’ll feel challenged, but never pushed into something that isn’t right for your body or your goals.

The gym has the feel of a small, local pub (but with less beer and more kettlebells). You get to know people quickly, and it’s easy to feel like you’re part of something—not just showing up for a workout, but belonging to a community that cares.

If you’re looking for a gym where you’re seen, supported, and taken seriously—without the ego or hype—this is the place.
