I have been training at Underground Fitness with Ron for a few months and I am blown away by his knowledge, expertise, and attention! At Underground Fitness each client receives their own personalized plan tailored to them and their goals. Ron and his team understand each individual is unique which calls for an equally unique fitness plan. During my sessions Ron pays the utmost attention making sure my form is correct and makes any modifications if I need- as someone with past surgeries this is huge! Ron and his team are some of the best in the game! If you’re looking for a highly personalized strength training gym with trainers that are experienced (especially with modifications) and has a great community feel then in you’re in the right spot!

Ron has been great to work with these past 3 months. He is very thorough in his planning, and listens well. He focuses on proper form, and has an excellent understanding of how specific exercises tune the body. Ron is also flexible with his schedule and the gym is a very welcoming place. Roxanne and all of his staff are very friendly and helpful.

I’ve been an experienced powerlifter for years, but I hit a threshold that I just couldn't break through on my own. After working with Ron at Underground Fitness for just a couple of months, I’ve seen more progress than I did in over a year of solo training. ​His knowledge and expertise are next level. What impressed me most is his ability to adapt; I have a fused ankle that has always limited my leg training, but Ron found intelligent ways to work around that obstacle and get me training legs effectively again. He doesn’t just give you a workout; he provides a process that truly works. If you’re looking for a trainer who is incredibly intelligent and can help you overcome any physical limitation, all while making it fun. Ron is your guy. And Underground Fitness is where you'll find him!

Fully equipped gym with focused trainer. As one who dislikes they typical gym energy, this small but mighty gym and trainer are perfect.. I receive one on one training in a small group setting that is designed for my specific needs and goals. The environment is clean and safe. Ron is easy to communicate with; I feel heard and supported. In only a few weeks I have noticed an improvement in my strength, physical appearance and overall confidence.

I’ve been training with Ron at Underground Fitness, and the experience has been great. From day one, he listened to my goals and tailored a plan that pushes me without ever feeling overwhelming. His mix of knowledge, patience, and motivation makes every workout not just effective but actually enjoyable. One of the biggest breakthroughs for me has been building confidence with free weights. Ron has a way of breaking things down and making lifts feel approachable and safe, which has completely changed how I show up in the gym. If you’re serious about results and want a trainer who genuinely cares about your success, I can’t recommend Ron enough.
