The Holy Spirit led me to leave this review today after being a member since December 2025…read more I praise God for how He is using Mark and Kat to help people become more physically healthy while also introducing them to what matters most--Jesus Christ. Their commitment to honoring the Lord through their business is evident. The facility is always well-stocked, the equipment is organized (unlike many public gyms), and everything is consistently clean and well maintained. It's a welcoming environment where excellence and care are clearly a priority. I truly believe the Lord will continue to bless Mark and Kat, both in their business and in their family, because of their faithfulness and obedience to Him. The Scripture that comes to mind is Psalm 37:5: "Commit everything you do to the Lord. Trust Him, and He will help you." May the Lord Jesus Christ continue to increase your influence, bless your work, and grant you favor as you faithfully walk in obedience to Him.

I cannot say enough good things about Alyssa. She is awesome! From day one, she has been organized…read moreand intentional with every workout. You can tell she actually plans everything out instead of just winging it. What I appreciate most is how thoroughly she explains things. She breaks down the why behind each movement, corrects my form, and makes sure I understand what we are working on. That has made a huge difference. I can already see changes in my physique, which is so motivating. I feel stronger and more confident, and she genuinely makes me excited to work out. If you want a trainer who is organized, inspiring, and truly invested in your progress, Alyssa is it.

I've been a professional personal trainer since 2009. I ran the entire training department for…read morelarge corporate gyms, and I still train clients I've worked with for over ten years. Any of them can vouch for me. In my entire career, I have never had a single billing dispute with a client. I know this industry from the inside, which is exactly why my experience at The Box has been so disappointing. I came to The Box in early 2024 on a strong recommendation from a close friend, and at first I loved it. My coach, Coach Yuka, is excellent, and I valued the many sparring partners I got to share the ring with. From day one, though, I noticed the owner frequently no-shows on clients and talks far more than he actually trains. As a trainer myself, I clocked it immediately, but I figured it wasn't my problem and kept it to myself. After everything that followed, I think it's worth letting people know he is not a serious coach. My issue is not with the training staff, who are great. It's with the owner and how the business is run. Every single person I sparred with at The Box was a good sport. The owner was the exception. When I got in the ring with him, rather than boxing technically he repeatedly lunged, and at one point threw his shoulder into my face after breaking up a clinch he had started. I hurt my back so badly I couldn't walk the next day. He let his ego surpass his professionalism, and what should have stayed a respectful exchange in the ring turned into something he then carried into how he treated me as a paying client. After that, I canceled my membership, and Mario confirmed the cancellation. A year later, reviewing my finances, I discovered he had been charging me the entire time. He agreed to refund me but only returned half of what I was owed. I let it go because I planned to come back and keep training. When I returned, I came with my family. Previously I paid about $60 a month for myself and my kids, so I expected something reasonable. When I asked about my missing refund, he said it had gone toward "enrollment fees." As a professional, I can tell you it is not standard to charge enrollment fees to someone who only trains privately once a week rather than using the classes and facilities. Those clients are typically given a discounted rate. We finally agreed, in writing, on $180 a month with no enrollment fee, to be charged on the 20th. Without any notice, I was charged $297. I tried to confirm the amount beforehand and the receptionist ran the card anyway. When I put the discrepancy in writing, that we'd agreed to $180 and I was charged $297, he never actually addressed it. Instead of fixing the charge, he replied with a long breakdown of "the actual numbers" and how much value I was supposedly getting. I didn't ask for a sales pitch. I asked why I was charged a different amount than we agreed on. That question never got answered. Instead, he cornered me and claimed I now owed $780 for a month we'd used, even though he had already agreed to credit me that month. So rather than refunding the payment I'd just made, he moved the goalposts entirely. Billing here is a nightmare. When it's time to collect, they're relentless. When it's time to honor an agreement or process a cancellation, they vanish. I've worked in this field for over 15 years and have never seen a client treated this way. I can't recommend doing business with this owner.

I've been coming here since February, and joining this gym has honestly been one of the best…read moredecisions I've made this year. At first, I was really intimidated. I had only ever gone to places like 24 Hour Fitness, so walking into a more serious training gym was completely out of my comfort zone. But from day one, everyone made me feel so welcome. The front desk staff is always friendly, and they even have a little coffee bar in the mornings, which is such a nice touch. I've been training with AJ, and I can't recommend him enough. Coming from someone who knew almost nothing about gym equipment or strength training (I was mainly a Pilates girl), he made everything easy to understand and made me feel comfortable asking questions. He's patient, encouraging, and genuinely cares about helping you improve. Since starting here, my body has changed so much, but honestly, so has my mindset. I've gained confidence, learned proper form, and actually look forward to coming to the gym. No matter what fitness level you're at, I've never felt judged or out of place. There are people at every stage of their fitness journey, and it's a really supportive environment. I've also attended one of their women's events, which was such a fun way to meet people and be part of the community. It really feels like more than just a gym. If you've been nervous about joining a gym like I was, this is your sign. I'm so glad I took the chance.

Then, ~1 year ago, I was interested in bulking up my legs for a more symmetrical lower to upper body physique and was introduced to Joe/Thrive Fitness. The goal was simple, build leg muscle. But here's the thing... we built leg muscle as a byproduct of lifting for performance and technique. Joe has this knack for pairing exercises (traditional ones and those uniquely Joe) that target the muscles groups in question, focusing on compound movements and exercises that keep your muscles guessing. This includes getting all of the tiny muscles in-between the big ones that strengthen your knee and joints for example. Without question, I knew that two days post any session with Joe, I was going to feel every muscle group in my lower body. Ok, so what's Joe like? The most energetic, excited for life, passionate for results kind of person you'll ever meet. Your goals literally become his. You become part of his tribe so to speak. Joe's also a great listener. His energy is contagious as he is seemingly running around the gym setting up your next exercise, circuit or simply taking pride in his passion (pushing you to your limit to achieve your goals). Please do yourself a favor and give Joe the chance to experience his methods and style... you will not regret it.

His program really tailors towards your lifestyle and is completely flexible. I am a full time dad/husband with a crazy work schedule. For the longest time, I wanted to find a fitness program that was simple, to the point, and built around MY own schedule. Coach Arturo solved that problem for me and honestly made the whole training experience feel like it's part of your everyday routine. His program became second nature, but in a good way. As understanding as coach Arturo is, he definitely makes sure that you are staying on track and making the most out of the program. He constantly checks in with you and is readily available for questions. He also provides motivational and beneficial information daily to help you get your day started. He is constantly trying to find ways to make yourself better everyday! The platform he uses is pretty amazing. You can track all your progress, workouts, nutrition, & weight in one platform. Arturo also dials in your macros for you to ensure you are optimizing your workouts for the most progress. He also pays attention to your other health factors such as your sleep quality in order to maximize your progression. I REALLY enjoyed Coach Arturo's program and made amazing progress along the way. If you are looking for a fitness program that is flexible, challenging, but also fun at the same time, I highly recommends Art of Fitness!
