I have been training at Underground Fitness for 3 years. Before starting at the studio, I was very overwhelmed and nervous because I had never worked out before. From the first day I walked into the studio, I felt so welcomed and felt like a priority. Dave is in charge of my nutrition. His knowledge and approach to flexible dieting has created a lifestyle that I will continue to follow. I am able to eat and incorporate foods I love (Lucky Charms) while seeing great results! I currently train with Jake and Alec and could not be happier. They are flexible with my busy schedule and give me a great workout every time. They taught me patience and to trust the process. I never thought I'd be able to get such good results without extreme dieting.

I hired Dave Bess and Underground Fitness in February of 2016 and have experienced remarkable changes in my lifestyle and lost 55lbs in this time frame. Dave worked with me developing a training routine that worked for me and also pointed me in the direction of making healthy food choices that have now become part of my lifestyle. I can honestly say that I feel better at 58 years old than I ever thought possible. If you are looking for a personal trainer I highly recommend Dave. When a person hires him you not only get an excellent trainer but you also get a lifestyle coach and a great friend!

The trainers are always kind, and if they can tell you're struggling they won't push you to the point of exhaustion, but will modify it so you aren't dying, but you're still doing a workout with the same effect. When they ask how you're eating, they also don't pull any of the generic "Are you eating healthy?" question, but focus on how you're eating and how you can improve. Overall they take good care of you and their other clients, and make sure you are able to lose weight, or become more muscular.

The decision to come to Underground Fitness Arrowhead to help me meet my fitness goals was one of the best decisions I ever made. Training with Jon in just 4 months, I've lost almost 7 inches in my waist and gained a new perspective into living an active and healthy lifestyle.I've had experiences at other personal training studios where trainers are too textbook. Sessions become boring and repetitive which led to idle results that were met with finger pointing and intimidation instead of problem solving. You definitely won't find that here.Jon at Underground Fitness Arrowhead promotes an intimidation-free, vigorous, yet propitious workout environment. Along with being highly knowledgeable about fitness and nutrition, he is very observant and devotes himself to ensure that my fitness goals are met in a healthy and injury-free manner. In fact, he's noticed my posture problems and hamstring weakness that he has molded unique exercises to help me burn calories, gain muscle, and correct those problems all at the same time. He even designed convenient and simple stretches I could do at home to supplement those exercises.Jon also solved the biggest problem I've had in trying to lose weight through the years: keeping a healthy nutrition plan constant and in check. He gave me certain calorie parameters and checks what I'm eating on a weekly basis to keep me accountable. He takes the time to answer any questions about my eating habits. No judgement from him, ever. I finally learned to eat healthy without depriving myself. No looking back.Jon does a great job of keeping me motivated to continue on this fitness journey. If he sees something not working for me, in a blink of an eye, he comes up with an alternative that'll provide the same benefits. He's always enthusiastic about my achievements. Sometimes I think he's more excited than I am. He truly demonstrates that this isn't just a job for him but a passion to improve his clients' lives by helping them fulfill their goals in a positive setting.

My fiance and I decided to go to Underground Fitness to get into wedding shape. We chose UF due to a Groupon. It was a great decision! We've been renewing for the last 4 months. Jon D is a great trainer. I'm very experienced in working out and my fiance is not. Jon took the time to listen to our needs. I told him I don't want to lift weights as I want to focus on more body weight exercises. Also I have had 3 knee surgeries so I can't push my legs as hard. My fiance is brand new to strength training so Jon had to teach her the basics of form and movements. He was very patient and not pushy. He catered to our needs without pushing on a cookie cutter workout. He challenged me and my fiance. The workouts are never the same which is great! Jon takes feedback very well as some exercises really does hurt my knee so he didn't really push me to finish he would simple switch to another workout that doesn't put too much stress on my knee. My fiance and I have seen some weight loss but more our body leaning out and showing more definition.Overall UF has very friendly staff. All the trainers will say Hi to you. It's a small bare bones gym but they have enough knowledge and equipment to get the job done. I would give it a try regardless of your experience. As I've learned a lot of new routines that kicked my butt!

I have been going to Underground Fitness since 2013. Training with Jon the workouts are always fun and he helps me stay accountable to reach my health and fitness goals. At Underground, they have worked with me to develop and maintain a nutritional program that has helped me to lose over 10% Body Fat and keep it off. Underground Fitness Arrowhead has become a necessity to my workout routine and I highly recommend the studio and Jon.

When I walked into Underground Fitness almost 2 years ago I had no idea that I would meet a personal trainer named Jon Dudzinski and my life would soon forever be changed.After gaining a lot of weight and going through a depression, I tried exercising at home, going to the "big" gyms and doing it on my own. Not only did it not work but I pretty much gave up on everything and soon after I was told by my doctor that I was pre-diabetic and if I didn't do something soon that diabetes would become a reality, and that is something I refused to let happen.I walked into Underground Fitness in October of 2014 and after my first workout with Jon I knew this was the best decision I could've made for myself!! I have dropped several sizes and the diabetes is no longer a major concern!! Jon has helped me get my self confidence back and I feel better than I have in years!!The workouts are personalized and the nutrition help has been amazing. While the workouts are tough, I don't feel pushed beyond my limits and I feel great and always look forward to the next one. I am able to do things that I never thought I would be able to do and I have not only changed physically but there have been amazing, positive changes in every aspect of my life. All of the trainers in the gym are very friendly and they all have a genuine concern for their clients.Jon is very encouraging and motivating and I can't help but look forward to my next workout! Jon is an amazing person and a great trainer! Jon is not just my trainer, he is also my friend and I appreciate EVERYTHING he does for me!!Thank you Jon and Underground Fitness!!

I always had intentions to develop my physique and have tried reputed fitness centers, home gym etc but never was able to achieve consistency due to my health issues. Walked into this place last Sep as it's very close to my house to see what they got. I never thought this guy I'm about to meet will change my life, people call him Dave Bess but to me Dave the BEST. In just 3 months, my body was transformed to the best shape of my life. Dave guided me through every workout. He understands every persons strength and weakness and designs workout that would work effectively. With my poor lower back, I was able to workout every part of the muscle in my body without hurting myself....many times I felt I must be dreaming. It's an awesome feeling when people ask "are you working out everyday man", but I do only 2 or 3 times a week here. The routines are dynamic that covers whole body and there is something beyond just training in this facility that makes me feel COMPLETE, only Dave would know the recipe.Last few weeks, I'm working with Jake Page and this guy is about to steel Dave's spot in my mind pretty soon. Jake knows the tactic, the muscle mind connection and certainly our own abilities. I can't imagine not going to UGF ever. He is very passionate in what he do and does it right. He always makes sure every muscle move is done right so we get the 100% results. Typically, the muscle tightness lasts for hours after workout but with Jake it's pretty intact until next workout...feels amazing!Jon trains a lot of folks there and he is down to earth personality and an amazing trainer too.I'm always in debt to Dave for his support and encouragement, without that I would be just a normal guy!!! This place has become more like a family to me and I feel great to be there every single time. Certain things we gotta try for real than just talks and this place would be a perfect example. Stay Fit!

The Underground Fitness team has really helped get me on the right track with exercise and diet. Not once have I dreaded going to a session for the entire three months I have been with them. I've worked with both Dave and Jake and they both are very energetic....they push you and give you the motivation you need to accomplish your short-term and long-term goals. If you are looking for a personal trainer, I would highly recommend Underground Fitness!

Started training at underground with Dave and John. work out with a good group of guys. I look forward to coming into the gym everyday. The training techniques are fun and knowledgeable. Dave's knowledge of nutrition has really helped me see a lot of progress. This has been a unique workout experience that I would definitely recommend to other people looking to get in shape. Dave even went above and beyond when he came to my house and showed me how to cook a healthy meal. The entire staff is great with people and you can really tell they care about the success of all of their clients.
