I’ve been working out at Underground Fitness in Glendale for about 1.5 years now, on and off. The first day I walked in Trisha was helping me and made me feel right at home as if I belonged there. She scheduled me with a trainer who would best fit my goal for building muscle. With my busy schedule I’m able to train at least two times a week, and I’m very grateful for all the trainers there. They are very competent and experienced in their own way which makes it the perfect gym. No matter what your needs are, you’ll be taken care of and you will reach your goals if you stay consistent, believe me. I recently went out of state for 3 months and I’ll tell you that it was not the same to workout at another gym. Something was missing and it was the trainers at UF. Now that I’m back it’s really amazing and the trainers made me feel like family. I would definitely recommend UF to everyone that wants to reach their fitness goals and wants to feel like they belong.

Can't say enough about the team here at this Underground Fitness! Over the past year, I have gotten to know all of the trainers personally. Dave, Jake, John, & Trish are all extremely knowledgeable and great to work with. I struggled for years with chronic back pain and needed to get into shape for a Spartan Race. Dave was able to get my strength and conditioning on point for the race all while strengthening my back and core. I can happily say that after all these years of chronic back pain, I am almost pain free! You can't go wrong with the team here. They all really care about you as a person and for that hour that you train, they make you feel like the most important person in the world. :)

I've been going to Underground Fitness for about 8 months now and I'm never looking back! I was a little skeptical at first because I had never done personal training. My brother had been training with Trisha for quite some time and was constantly trying to get me to tag along. I decided to go for the first session with Trisha and I've been going ever since then! Trisha is really knowledgeable about personal training and customizes her routines per person. But more importantly, she really pushes you to go one step further each time. I've lost 20 pounds so far with the nutrition plan and the workouts and I don't plan on stopping now! Not just Trisha, but every other trainer as well really cares about personal training and they all want you to become the best version of yourself. It's truly a supportive and fun place to exercise! Thank you Underground Fitness!

I have been training at Underground Fitness for 2 years now, I train with Jon and it has been a great experience. Jon has a very unique motivational style that took some time getting used to at first, but when I did, I hit my stride and never looked back. I have made a tremendous amount of progress under his stewardship, he is extremely knowledgeable and always goes the extra mile. There is a big focus from the team on aligning the training with nutrition and all trainers are very knowledge in this area.The overall Underground team is great to; very friendly, motivating, not pretentious in anyway, great place to workout. Appreciate everything the team there have done to improve my fitness.

Underground Fitness is great! It's the perfect spot for those who don't like going to gyms, or those who don't know what to do at the gym. Each one of the trainers has their own style of training and each style works in it's own way, no matter who you are or what you're looking to work on. They help you track what you eat so that you are able to take full advantage of the membership. The trainers are very personable, making everyone they work out with feel like they are a friend and belong at the facility. Dave is great at focusing on specific muscles during a routine and helping build muscle. Trisha is the best at working on your mobility, not using a lot of weight but focusing on movements and flexibility.

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.

This place is great! I came in about a month ago looking to drop some lbs and get back into shape. In the first month I've gone from 239lbs to 225lbs. Jon set me up with a great plan to meet my goals. The workouts are challenging but fun, and there is a nice variety to the exercises. I tend to get bored if I'm doing the same workouts over and over, I've been here a month and haven't been bored yet! I can't say enough great things about Jon and the rest of the staff there!!

I've been working with Kerry with online training for a little over 6 months. Can't tell you how incredibly relieved and happy I am to have her support and knowledge. Went from thinking I knew a lot about diet and exercise to actually learning to fit proper diet and weight training into my lifestyle. I still have a long ways to go but I'm excited to have Underground Fitness along with me on this transformation/fitness journey. My mental state, lifestyle and body is going through a complete overhaul and the only thing I regret is not starting earlier. It's been worth every penny having Kerry as my emotional support and biggest cheerleader. Can't wait to see what these next 6 months and beyond have in store for us.

Jon Dudzinski has been my Trainer for 4 months. I have found him to be knowledgeable, patient, encouraging, professional, friendly, creative and possess' s a nice personality. As my Trainer he has been able to bring variety into my workouts which keeps my interest and commitment at a high level. I am enjoying the benefits I have gotten from working with Jon. I feel confident to recmmend him to someone else.

When I joined Underground Fitness 4 months ago I had no idea I could feel this good. I had trouble with balance, not anymore. I had trouble with core strength, not anymore. I had low self esteem, not anymore. My personal trainer, Trisha, keeps me motivated and challenged, even when I'm not at the gym. I've dropped two sizes and feel great! Thanks to Trisha keeping me in check, my goals are now being achieved.
