    I began training at Serious Strength because I wanted to gain more knowledge around personal fitness. Ovi was my trainer, and he is an excellent training coach! He taught me countless exercises tailored to my fitness goals, and now I’m fully confident to lead my own workouts.

    I have trained with Rob over the last few years, following him through several gyms. His true home, Serious Strength, is where it is at if you want a true personalized training experience. Combined with Rob's in-depth and continuous study of personal training plus the private training facility with the most up-to-date equipment will make any training experience more worthwhile. There is no hassle with other gym members waiting for their turn with equipment because it is only Ovi and Rob who train at their location, so there is more time spent on you and your fitness goals. Definitely give them a try if you are in the market for the true personal training experience.

    Rob is my very first trainer. He’s a true example of an ideal fitness coach! I get the education, the encouragement and the genuine support I need during my fitness journey. If you’re committed to seeing legit results and want real strength training, I highly suggest making this guy your trainer!

    I'm so happy I decided to go to Serious Strength. I've had training sessions with Rob and he's very patient and keeps me motivated to really give it my all. We have discussed goals for my workouts and ways to improve my meals so I can achieve them. I also got to meet with Ovi during my first session and he discussed in depth health goals. They both really care about their clients. If you're like me and uncomfortable in crowded places, then this is the place for you. It's a great one on one experience with an experienced trainer.

    I have been training at Serious Strength for a year and a half now and I can honestly say this is the best gym experience I have ever had. Ovi and Rob are excellent personal trainers that are truly passionate about helping their clients. They listen to their client’s goals and provide a detailed plan to achieve them. The gym itself has the absolute best equipment I’ve ever seen. Serious Strength has every premium piece of equipment you could imagine. Lastly, the environment is so positive and fun. There is a sense of community amongst all of the clients and we motivate each other to be the best version of ourselves. If you’re looking for a new gym and personal trainer, Serious Strength is the best that’s out there. You will not be disappointed!

    Serious Strength Personal Training has been hands down, the most positive and motivating personal training experience I have had. On top of that, I don’t say that lightly since I have been training with Rob for about a littleover a month. It has made a big impression on me.In the time I have spent training, I have felt welcomed and listened to on so many levels. Ovi and Rob spend time with each client, crafting training programs with individualized goals to meet you where you are at and to get you where you want to go. This was highly important to be having come from past experiences feeling that I am pushed to hard to do something, injured from training or felt that my goals weren’t being taken into consideration at all.I appreciate the professionalism, knowledge, approachable and passionate stance they take to help people (including myself) become the strongest they can be. The training environment is amazing and caters to one on one sessions with a truly positive approach. I can safely say I am just as serious about staying with Serious Strength long term as they are with their Personal training approach.

    I should have written this sooner, but I cannot say enough good things about this place!I came to Serious Strength when I was at point in my life where I needed help with my health goals, but didn’t know where to start. Rob never made me feel bad or intimidated. Instead he mentored me and coached me to becoming a more confident person in the gym environment.No matter where you are in your journey, Rob is an amazing person to guide you to where you want to go. He’s strict when he needs to be, but it’s only because he cares about you and your goals. He can also adjust to your restrictions if needed. The equipment and environment is everything that you hope for in a private gym.Please see it for yourself! This team works hard everyday to see their clients succeed. This is worth your investment. ?Thank you guys for building a community and I hope to join it again soon! ??⚡️

    I recently started training with Rob at Serious Strength and his level of professionalism and expertise is great. He provides training sessions that challenge me, keep me motivated and allow me to progress from my current fitness level. He also provides meal plans and check-ins that hold me accountable.I had a surgery a year ago and I still deal with intermittent hip/low-back tightness that makes it difficult to perform certain movements, but Rob provides workout modifications that have increased my mobility and overall strength.I’ve trained with Rob in the past at a different gym and he helped me reach my fitness goals at that time. Looking forward to meeting my current fitness goals with his guidance once again.The facility itself is clean, has great equipment and it isn’t crowded like other gyms. 10/10 would recommend checking out Serious Strength!
