I have had a really good experience here thus far. Kasey Gibbs is my trainer and is very good at what he does. He learns what you like/don’t like, safely pushes you to your limits and beyond, and gives great tips along the way. I knew a lot before starting training with him, but he has already taught me so much more. Everyone is also very friendly which is a plus. Training here has been a great motivator to stay healthy and in shape while learning new and useful exercises/tips to continue building muscle and burning fat. I feel the strongest and healthiest I have in years.It’s a little pricey but you will get from this what you put into it and is ultimately worth the investment in my opinion. Also, they have very helpful payment plans that make it easier to manage! (There is no better motivator than having financial skin in the game and a trainer who will keep you accountable).

What a wonderful team of people! I say team, because that’s what you get when you join this program. You work out 3 times a week with a personal trainer. My trainers are having me do specific exercises for my body type and to help build up my back from a lower back injury.Also, I have a nutritionist who helps me with meal planning, and also calls me weekly to see how I’m doing.The encouragement I receive from the staff is so uplifting, and I am closer to reaching my fitness goals. Underground fitness is a very positive environment, and I actually look forward to my workouts.

I’ve always considered myself a fairly healthy guy. I played sports all my life and have always been an active person. In my younger years, I depended on my youth and metabolism to keep me in shape. I ate how I wanted and never really tipped the scale too bad, but in December 2010, I found myself married to my high school sweetheart, and 230 lbs and I’m only 5’6”. That was literally the heaviest I had been in my life at the time. I walked into a gym in Farmington, Missouri and ran into a very energetic guy. I spoke with him about training and getting in shape. His name of course was Dave Bess. I had the luxury of being his first client EVER…lol. Needless to say the results were amazing. I went from 230 lbs to 193 lbs in matter of 16 weeks. No fancy diets, just hard work and dedication. So, fast forward 11 years, and wife and 2 kids later, I sat at 228 lbs and not knowing how to get out of it. As an ex athlete, working out is easy for me. But whenever I started, everything else in my life became unbalanced, which led me back to doing what was easiest, just making it through the days. I wasn’t built bad but I just needed guidance. How do you balance it all? How can you balance being a Christian man, husband, father, career, and self care all at once. As a father I wanted to show my wife and kids a good example of a man who could have it together spiritually, mentally, and physically. I also suffered with thoughts that’s my health was in jeopardy any way. My father, and both of his brothers all died at early ages from prostate cancer. My grandfather who passed less than a week ago also had prostate cancer. So obviously you get a feeling that your future is doomed. I was in a frustrated dark place when it came to the wellness of my family and myself. Eight weeks ago I sat on the couch scrolling facebook and I saw a live video from Dave and he asked “What trips you up when starting a plan?” I commented on the post, but I didn’t expect it to go any further. Out of the blue I received a FB message from Dave asking if I wanted to get together on a zoom a chat. I agreed. We discussed not just weight loss but we discussed life and all the important pieces of that make it worth living. He laid out a plan. It was not just about working out but, it included time for spiritual walk, time with my wife and kids as well. It was a wellness plan, not just a workout plan. Before starting the transformation plan I had no discipline at all. I didn’t realize the importance of planning your health walk the same way you plan on your job. It helped me to get all of the pieces to the puzzle and finally put them together. In just 8 short weeks I’ve come down from 226 lbs to 202 lbs, and I even have my family on board with me. I have seen changes in I my physique that I haven’t seen in a long time. The meal plan is not strict but it does involve making better choices as you should in life. Dave and I speak on a weekly basis and the topic of discussion is “How do you feel?” Its not just about body gains and workouts. I would definitely recommend the 63 day transformation to anybody that needs the total package of achieving results and learning how to do it properly. I plan to eat and live this way the rest of my life. At this point in my journey I feel as if all the pieces of me are coming together. My family and I are opening other areas of interest with each other. Health and wellness is becoming a natural part of our lives. Thanks to Dave Bess for a second time!!!

TLDR; signing up for the 9-week transformation was hands down one of the best decisions I've made for myself in quite a while. They give you the tools to bet on yourself, and win.I had attempted to lose the 25-30lbs id put on for ~2-2.5 years with zero traction. I would start enthusiastically, and when I didn't see ANY results, I'd either give up completely or take my foot off the gas considerably. Then wash. rinse. repeat. I was completely hopeless and frustrated with my self and my life.Enter underground fitness.I left my initial consultation with Dave feeling almost giddy (and. don't use that phrase lightly). Everything he said just clicked - for the 1st time in a long time, it felt not only possible but likely that I would be able lose the weight.And 9+ weeks in that feeling hasn't gone away. Thanks to Dave and my Trainer Tripp (honestly one of the most knowledgeable trainers i've ever met), and despite my newly discovered hypothyroidism, I've lost 3 inches off my waist, I have the confidence to take pictures with my family/niece and even been able to bring a few items of clothing out of retirement! And all this was possible without being forced to eat salads or protein shakes all day.Dave taught me how to be accountable for myself and my food. If I want dessert, and make sure I have it budgeted into my daily calories and I eat that dessert. He genuinely cares about his clients and his only goal is for your to reach your goals, and in the process teach you how to eat for the rest of your life. Honestly, could have easily gotten double the money out of me for the following 9 weeks program but because I was doing well with my nutrition, he moved me to a less hands-on 9-week program.And frankly, Just knowing that I know how to lose the weight and keep it off and that I won't have to deal with this issue again is pretty mind-boggling.

I am so glad my chiropractor recommended UF and trainer Jon D to me about a year ago, saying I needed core strength to keep from continually throwing out my lower back, which I had been dealing with for decades. I am especially thankful to Jon, who has been the perfect trainer for me, always friendly, motivating with kindness and respect, and never overbearing. Through Jon’s expert guidance and personalized plans, I was able to make surprisingly quick progress toward my objectives of eliminating the lower back issues plus gaining overall strength, endurance and definition. In my early 60’s, I am so happy to be in the best shape of my life, and I plan to continue with Jon at UF indefinitely!

Underground Fitness is a great gym! I signed up for the 9 week program and it was exactly what I needed. They focus not only on getting physically fit but working on the mind and spirit as well. The owner Dave set me up with his custom system that helped to hold me accountable to goals that I set for myself. He also set me up on a meal plan that is simple and has been a game changer for me. The trainer CJ is extremely knowledgeable in all facets of strength training whether you are looking to drop 100 pounds or bulk up and put on muscle mass.Overall I would highly suggest checking this place out. You will not be disappointed!

Underground Fitness hands down! Is the best training facility to train at. If you are looking for a quality trainer who knows what they are doing and motivates you through every workout, stop looking and join Underground Fitness.I have been coming to Underground for the last 10 months and have had the best results I have ever had in the last 2 years of working out.I came in with a goal and when I was introduced to Dave, not only did he tell me what I needed to do he put together a plan for me and made sure I executed the plan. 10 months later I have seen results I have never seen before. I will continue to train with the best trainers in the Valley!

Everybody here was so kind and down to earth- I cant stand the typical atmosphere of most gyms with meatheads. When I walk in, I feel no judgement. Jon was super kind and professional and was willing to sit with me for a while and discuss my goals and how to reach them, and how we would reach them together. Very good experience!

I was stuck in such a rough patch in my life, I’d hardly eat more than a meal a day, or would mostly consume junk food, and would rarely work out. After getting out of a toxic relationship, I found underground fitness after looking through several gyms, and this one seemed the most genuine to me, which IT SURE WAS. One of the first things Dave told me during our first walk in meeting was “We don’t just want to transform you for 9 weeks, we want to help and provide you with knowledge that will benefit you for the rest of your life.” Everyone at the gym is so friendly, I felt absolutely no judgement from anyone there. Both Dave and Liz showed me so much kindness, and have helped me sooo so much. I highly recommend this place to anyone who’s looking for a lifestyle change with a happy, loving environment!

I love underground!! Trisha has been training me and working with me for the past 5 weeks and I’ve seen such great progress!! She’s an excellent trainer and knows what she’s doing. She always takes the time to write down my workouts so I can easily repeat them. I would definitely recommend her or any of the underground crew to anyone who is looking for a personal trainer.
