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. read more

I'm sharing this for safety reasons. During a squat session a few months back, I told my trainer that my back was hurting during the squats. Despite this, I was instructed to complete another set. During that final set, I injured my back badly enough that I could not walk afterward. At no point was the exercise stopped, reduced, or modified when I reported pain. I still can't squat, my back isn't fully recovered. Afterward, communication was disappointing. When my husband and I later explained that we needed to pause training due to finances, we received no response. Regardless of certification or experience level, a trainer should prioritize client safety, listen when pain is reported, and communicate professionally. Unfortunately, that was not my experience. Update: After posting this review, the trainer contacted me and offered me money to take my review down. Since he can't contact me he reached out to my husband regarding my review. I am adding this update for transparency. read more

I wanted to leave an update on my experiences at Underground since I joined last fall. The owner/trainer Kevin D. is truly phenomenal at what he does. He is 100% dedicated to helping his clients reach their goals at any level of fitness. I have had a whirlwind of sicknesses and pulled my back at one point. Normally that would discourage me but Kevin was always understanding and would modify any workouts to maintain my strength while remaining cognizant of my ability at that time. The folks I have met through working out here have also been a wonderful addition to my experience. I have learned so much about myself, nutrition, strength training, and metabolism since coming here and I am eternally grateful for this gem of a business. read more

I have been going to Underground Fitness for about a month now and am really enjoying it. After living a sedentary lifestyle for a number of years, it has felt great to get back into a gym and not feel overwhelmed. Kevin Denz has been great and is very knowledgeable about all of the equipment and the metabolic system. His approach is educational and non-intimidating but will push you to find your limit. I really appreciate Kevin's philosophy of encouraging his clients to make healthy lifestyle changes congruent with their values and goals. read more

We just started our second 9 week session. Our biggest concern in starting was that it would be too much for us since we hadn't worked out for many years. Kasey, our personal trainer, made sure to give us exercises that were challenging without overdoing it. I've noticed differences in overall strength and am more comfortable just living. I told him I had an injured knee before we started. He took care and concern to give me exercises to strengthen my knee and I am happy to say that it improves with each workout. We are very happy so far. read more

I have been with UF from the past 1.5 years and I can't say enough good things about these guys. The whole vibe at UF is extremely encouraging and positive - thanks to all the trainers - Trisha, Jake, Dave, Jon (and the new guy) who make each session very much focussed on individual needs and at the same time, they are absolute fun -- intense but fun :-) Thanks to Trisha, I lost all those extra pounds I put on (working from home is really dangerous for the waistline :)) but most importantly, I gained strength, a bit of muscle (yayyy) and an understanding of how a correct posture can help enhancing the exercise routine. Did I say that Trisha is a stickler for correct posture :-D? The best part - I gained enough confidence to venture onto a single day 'Rim-River-Rim' hike at Grand Canyon - not recommended by NPS and I wouldn't recommend unless you are extremely prepared well enough. I finished the whole hike in 14 hours and lived to tell the tale :) Without all those leg days, which I seriously dread even today, I couldn't have ventured onto this adventure. For a guy who had a tough time climbing the stairs at my home, this is indeed extra special. Thank you, Trisha, for helping me in this journey. You are a rock star!! Give these guys a try. They can really change your life :-) **Pic on the left is from Dec, 2017 and the pic on the right is March, 2019 from Grand Canyon read more

Underground Fitness and my coach, Jake, especially have been a wonderful source for reaching my fitness goals this Summer. Even 700 miles away in the state of Utah, Jake was present with me over the phone and text during the entire program! Not only was I constantly encouraged, but I was challenged in a way that made me want to excel toward my fitness goal. Jake's uplifting attitude and constant vigor to encourage and motivate me was greatly appreciated. I would highly recommend Jake, and Underground Fitness if you're finally wanting to meet the goals you've always wanted. Now it's time for my wedding, and I'm sure i'll be back post-honeymoon ;) read more

I have been going for over month now. My schedule is 2x a week with my trainer Jake. Jake is awesome. He makes the workouts fit me and he does challenge me. He has a tough client on his hand, since I have a bad lower back, Valley Fever, and fungal meningitis. Love that he reads up on my condition and figures out how to keep me activity, motivated, and get me back into shape. The gym has all the equipment you need to work out and it is a nice chilled atmosphere. Everyone there is super friendly! read more

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! read more

This is the place to go if you're looking to get in shape the right way and see lasting results. Dave and the team will work hard to help you, not only when you're in for a workout, but outside of the gym as well. They'll get you squared away with a nutrition plan that will get you results without leaving you feeling starved or hangry. After watching my belly get bigger over the past couple years I came to underground to get my diet and exercise into check. My experience training with Dave for the past few months has been awesome. He keeps up the motivation with positive energy and makes sure that we work out smart - we do challenging, dynamic exercises without risking injury. I've already seen an increase in strength, endurance, and my overall energy level. The best part is that we genuinely have fun and I know that Dave and his team are invested in everyone's success. I can't recommend this place highly enough. read more

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 my transformation is going as planned with the help of Dave . I will continue to train with the best trainers in the Valley! read more

I destroyed my foot in early April so about a month ago I decided to seek a personal trainer to help with the rehabilitation--my goal is to get back onto a basketball court sooner rather than later. I looked at a few places in the area, but when I walked into Underground Fitness I knew I was in the right place--the vibe was right and the music was right, so I violated my own personal boycott on all businesses on Yam properties and signed up. I was hooked up with the rehab specialist, Trisha Thurston. Trisha is the real deal. This was perfect; some other people who work out here have nicknamed her "the assassin" and I had explicitly asked for a "drill sergeant" because when I was in high school I had worked out with a world-champion bodybuilder who, as I had said, "had an assassin's mentality" towards workouts. There's no use going for training if all you want is for the trainer to tell you that a light workout is just great. At the same time right now I have to be a little more careful, and Trisha gets that--which some other drill sergeants might not. Trisha has worked to strengthen the muscles around my foot, also around the other ankle (in which I tore a tendon some time ago), and to help me regain my balance on each foot. She's really focused on my calves, glutes, hamstrings and hip flexors, and I feel better and stronger after each workout. I highly recommend both Underground Fitness and Trisha individually to all those who, like me, are in need of some help building back their strength after a major injury. read more

Had worked on my own to lose weight and gain a higher fitness level and got to a stagnation point. Worked with Dave and CJ and got over that hump and to address both of my concerns. Worked with Dave to coordinate a plan of attack that included nutrition, stretching, yoga and a consistent routine, while Cj worked with me on workout routines. Both were easy to work with and their relationships with all of their clients is top notch. Went from 254 lbs to 234 lbs on my own, but needed that push to get me to 210lbs. This gave me a smaller waist, better fitness and more confidence in what I can accomplish. Thank you gentlemen. read more

I do not have enough amazing things to say about Underground Fitness or Dave and Kerry and truly the entire team. When I started with them I was leaving an awful coach who was starving me while training with them for the past 5 months I have regained a healthy relationship with food. LOST weight while eating MORE! And began enjoying every aspect of the gym again. Dave constantly challenges me every time we work out. Kerry is always a text away no matter the time of day or what they are doing. The gym has a friendly family atmosphere that never makes you feel ashamed of where you are starting or what your goals are. I cannot recommend them enough. No matter what you are wanting to achieve they can help you. read more

(Updated review)- I've been worked out with Jake almost a year since I joined the semi-private group. I have to say I feel really lucky to have him as my trainer. I was total new on weight lifting and workout area. He corrected my forms on day one, make sure I won't hurt myself, and push me on different levels gradually. Now I totally fall in love on workout and enjoy the changes on my body. I feel leaner, stronger, and with more energy ( yes I even love the soreness on the second day):) Trained by Jake, I truly love and feel his passion being a personal trainer. He is really knowledgeable on all the movements and knowing which exercises are beneficial to his clients. Most important, Jake has positive attitude on his job and his clients. He believes in his clients can be better & try to help as possible he can. I strongly recommend Jake as personal trainer. All other trainers in UGF are super nice and willing to help too. read more

I have been working out with Jake for over 1 year and have had some great results. Jake is motivating and encouraging. He knows an abundance about fitness and nutrition to help you reach your goals. I have definitely gain muscle in my arms, chest and legs. He mixes up the exercises so you will not get bored but always makes it challenging. The gym is very clean and the team there is the best I have encountered. Everyone is very friendly and the people that train there are very diverse. It is not all bodybuilders and models. I highly recommend Underground gyms as they have a few around the valley. Dean read more

I have been going to Underground fitness for a little over 1 year. My primary physician recommended weight training as I had a major gastrointestinal issue a few years back and had lost 20 percent of my body mass and at least that much of my muscle mass. First Alex worked with me, then Dave took over when Alex transferred. 3 days a week and I feel stronger than I ever have, then I started with Trish about 4 months ago for another 2 days a week for lower body and flexibility. I can honestly say my golf game has improved, my flexibility has improved I'm definitely more ,I guess you'd call it sculpted. And I feel a heck of a lot better, stronger, and obviously my self esteem has improved. Thanks Underground Fitness Steve Moore read more

I love this place. I have been coming here for a month now and it's fun everyone is friendly and a very positive vibe. The gym is small which I like. They know their stuff and they are always making sure you are sticking to your diet. They do care about about you and want you to achieve your goals. I get the one on one sessions and you get a good work out for that hole hour. I see them 3 times a week. Having Big Dave one day and John the next. They are both equally good and have different techniques. I don't call John the assassin for nothing when its leg day with John you feel it. Since I know they will read this I am not complaining only complimenting. LOL read more

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 welcome 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 at to trust the process. I never thought I'd be able to get such good results without extreme dieting. read more

In March of 2020, I was paralyzed. I couldn't pick up my feet. After a week in the hospital getting treatment and physical therapy, I spent the greater part of the next 6 months in bed. Where I proceeded to gain T H I R T Y pounds. As of January of this year, I couldn't even walk for more than one straight block without feeling winded and burning in my chest. I was soooo fatigued all day every single day. I hit a low and knew I didn't want to live one more day like that!! I made small diet changes and just tried to move. Small walks. A bike ride on my cruiser. Basketball with the kids for 5 minutes. Any kind of movement I could tolerate. I lost the first 10 pounds on my own . In March of 2021, I knew I needed to start rebuilding strength, muscle, stamina, balance, all of it. My nerves are 100% recovered, but my physical limitations made me hesitant to jump in to exercise just anywhere with just anyone. And so? Dave Bess at Underground Fitness to the rescue. I signed up for an intense 9 week HOLISTIC program. A HEALTH program that starts with mindset. No diet pills. No cereal bars. No magic serums. None of that. Truly working on healthy practices from the INSIDE out. Mindset, calorie tracking, weight training, working with a movement specialist, daily check-ins and encouragement, yoga, meditation, I could go on and on. Here are my 4 week results after working with Dave and his team. Almost halfway through the program. Honestly? Eff the scale. Forget the numbers. I would be happy to lose ZERO more pounds just to FEEL the way I do, today. My energy is UP. I sleep amazing at night. I don't have pain in my feet when I get out of bed in the morning. I can keep up with my kids. And I'm not even halfway done!! This journey is to be continued. I'm looking forward to a healthy and happy 2021 read more

Where do you start when you are turning forty years old, and you are dissatisfied with not only your body but your health as well. I felt like many people that the big gyms are intimidating and I was nervous about where I should start, what I should eat, how many days a week should I work out, and how should train. The staff at underground fitness made feel comfortable during the initial phone visit, to the initial consultation and my very first workout. Dave customized a plan for my own needs and enlisted Trish to assist me with my mobility and cardiovascular training. After training four days a week for six months, the transformation has been fantastic. I only have one regret, I wish I would have taken that first step, of making that first phone call earlier. Thank you, Dave, and Trish. read more

These guys are great. CJ is an awesome trainer, absolutely love harassing him each morning. Dave and CJ are both extremely knowledgeable and do their best to help keep you motivated. It's all up to you but they are great cheerleaders and definitely want to see you succeed. The first place I found that helps with my diet and doesn't force me to eat stuff I don't like. They give great suggestion to substitute foods. read more

This gym has it all- from private, and semi-private sessions to group training. It's a one stop shop for reaching your fitness goals. They do meal planning and even teach you how to meal prep at your house. So thankful for the progress I have made so far with Alec. He is really conscious of my prior ACL sports injuries and makes sure all the exercises are safe for me. The rest of the team serves as a really positive support system and provide compliments and uplifting sentiments during your fitness journey. This is way better than those cookie cutter meal planning and exercise routines at the "everyone gyms" as everything is customized to your fitness goals and realistic outcomes. Anyone who is considering getting some help with training or loves challenging group workouts check this place out! read more

The staff is kind and knowledgeable. The equipment is starting to show its wear and tear though. One of the treadmills is busted and has been for months. One of the pull down machines no longer has a smooth clean pull but a jerky stuttering pull. The leg machine had a split in the seating part right where the back of your knee meets it and that tears up your leg. read more

My body transformation with Dave Bess (my trainer) at Underground Fitness Arrowhead is like the infomercial's you see on TV for P90X. I'm a 52 year old guy with a 40 hour a week desk job. My goal, before meeting Dave, was to avoid getting fat like most of my coworkers. I was doing cardio and some light weights 4 to 5 days a week just to maintain my weight and I was busting my butt. A friend of mine suggested meeting with Dave (for a free consultation) after working out with him for a few months. I could see the great results my friend was getting so I decided to give Dave a chance to see what he could do for me. I'm 6 feet 2 inches tall and weigh 230 pounds. I have been with Dave for 4 months now and I have packed on about 10 pounds of muscle and lost about 10 pounds of fat. My weight has stayed the same but I lost 2 inches on my waist. My old shirts are all very tight around my chest and arms. My arm (bicep/measurement) is 17.5 inches when rested for a few days (18+ when pumped from a workout). I work out with Dave 3 hours a week for 1 full hour each workout. Dave monitors my nutrition and has set me up with realistic nutrition targets (Macros: calories, carbs, protein and fat). I log everything I eat in an interactive app (on my phone). Dave has 24/7 remote access to my information and keeps me on target. The bottom line is I look and feel fantastic. I get complemented on my physique every day by people I know and sometimes even strangers. They ask me how I got in such great shape and I tell them about Dave. At 52 I'm in the best shape of my life thanks to Dave Bess and Underground Fitness. I would never have been able to achieve these results fumbling around in a gym on my own. I look forward to seeing how the next 4 months with Dave will impact my body. read more

Have always hated gyms, being watched, surrounded by in-shape people. But, I have future surgery plans and knew I had to "shape up" so I could heal faster. Had a Groupon for a personal trainer at Underground Fitness. Met Cody, was a little intimidated at first, but his knowledge and experience quickly put me at ease. I have a bad knee which kept me from exercising until now. Cody has shown me exercises to strengthen my thighs and core to prevent any further injury to my knee. Kudos to Cody, a corrective trainer for putting me through workouts that have not inflamed my knee. I will keep up the good work, makes me so much better about myself and I sleep like a log now. read more

It's been a year now since my husband began his fitness journey (I joined a few months later after knee surgery) and Underground Fitness and personal trainer Cody is exactly what we needed. Cody has superior knowledge about anatomy, physiology, and metabolism which helped change how we both eat and exercise. I've been a regular exerciser for years, but am stronger than I've ever been. My husband has not exercised with any regularity but now is 5+ days a week and looks/feels great. Cody's workouts are appropriately challenging for each of us. Plus Cody's fun and funny which makes working out a joy. read more

From day one I have always been comfortable with the staff at Underground Fitness. I have been training with Dave for several years and what a difference he has made. He is always energetic, upbeat and encouraging. He makes sure that my form is always on point. I am much stronger and more athletic than I ever thought I could be. As of recent, I have been working out with Jake. He is truly passionate about his job and his clients. He has had me try thing that I was sure I could not complete, but I have. He keeps the workouts interesting, challenging and is very knowledgeable about how the body works. He is always aware of any injuries or areas you may need to watch during a workout. As I always say, I pay for the gym instead of therapy........I have two of the best "therapists in the world." read more
