I cannot say enough good things about the team at Underground Fitness! I have had the good fortune of working with several of them over the last year and a half. I've done one on one training several times a week, and love their group sessions as well! I recommend Alpha Hour!Dave has been great at helping me get my diet sorted out and directing me on a solid workout routine! Alec took the time to identify my specific wants and needs and built a regiment that has helped me achieve them!And when I injured my shoulder, Trisha adjusted my workouts to rehabilitate my shoulder while still working towards my overall goals.And Saturday's with Jake are great! He's a machine!Give this place a shot, you'll thank me for it!

I have been going to Underground Fitness for almost 2 months. This is the BEST gym I have ever been to by far. I lost 20 pounds in the first month alone with the help of my trainer Jon! Jon has always been very encouraging and has personalized my nutrition to help me reach my goals. I have worked with both Jon and Jake, and both have taken the time to listen to my needs. The workouts are challenging and motivating.Thanks so much Underground Fitness!

It has been 2yrs since I have joined Underground and its been a blessing. I am one of the lucky ones in the gym. I can honestly say that I have had the opportunity of working with all the trainers in the gym, even the new kid Jake or Jake the Fake as he is known. The nicknames come from Big Dave, don't ask just go with it and have fun.I have had Jake the Fake train me now for a couple months ever since he came to Underground. I see Jake once a week at least and I still see my main man Big Dave. From my first workout with Jake he pushed me hard and he continues to push me to my limits every session. I'll be doing a set with Jake and I can see and hear Big Dave from across the room in amazement and dropping the S bomb a time or two. Jake is very good at what he does and explaining things and showing you. Especially with body sculpting moves.As a Flight Attendant with a crazy schedule, half the time I don't know if I am coming or going. They are so great working with my crazy schedule Not only do they put me through a workout but they have put me on a diet. Teaching me how not only to eat right but how to meal prep each week. Learning how to meal prep has saved me money in the long run. I am still able to add the foods I enjoy like a Pop tart from time to time.All trainers at Underground are the best of the best and they are unique in their own ways. If you ask me who is the best I will always say Big Dave, he is my main trainer and I also consider one of my best friends. If you ask me who is second best well I couldn't tell you since they all are great.

As somebody who had never lifted before, I needed some place with an experienced staff that could work with me and guild me through a lifting and nutrition program. Over the years I’ve worked both with Dave and Jake who both really understand the science of lifting and eating that’s needed to fully develop muscle. Since starting I’ve added more than 25 pounds of muscle and completely changed my physique. Also since starting I’ve entered two bodybuilding competitions, winning one! Thanks guys for all the help and guidance. I highly recommend them.Doyle

Finally found the perfect trainer. Trisha was super knowledgeable in every area you'd expect an expert trainer to be! She help me improve from the inside out, pushing me to achieve my highest goals while beaming with addictive positive energy. 5 stars!

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.

I have been working with Dave for the past 2 years. I'm 68 years old and in the best shape I've been in since I was in my 30's. I have improved my strength and balance tremendously. By using flexible dieting and counting my macros under Dave's guidance, I have achieved the look I desired without starving or depriving myself.

I absolutely love working out with Dave! He is very personable and accommodating to any injuries I have. He has a lot of patience and gets to know all of his clients. He is always available to help you even outside the gym. Next goal: sweating for the wedding! Thanks Dave!!

I have been going to Underground Fitness Glendale for 6 months now and absolutely love it! Jon is very knowledgeable and very supportive and helpful in achieving my fitness goals! For a person with no self motivation when it come to fitness this is just what I needed.

My new physician suggested weight training as I had lost about 20% of my body mass due to a major gastrointestinal surgery.Underground fitness was a cross the drive so I walked in and met Alec Allen, liked the guy and decided to give it a try.Started in January, had knee replacement surgery in Feb. Then the real work began. I have lost 5% body fat, gain about 6.5% muscle mass.Alec, looks out for my knees, my low back (3 vertebrae fused) and has helped me transform my body to a much younger version. At 68 years young, the transformation is much more than I expected.Alec doesn't push, but challenges me to push myself, has quite a humor, and is really fun to work with.Originally I was 3 days a week with golf 4 days a week. But decided I had the energy, the drive and now work with Alec 5 days a week.ANYONE LOOKING TO GET INTO SHAPE, LOOKING TO TRANSFORM THEIR BODY SHAPE AND DIET, SHOULD SEE ALEC OR DAVE AT UNDER GROUND FITNESS. IT'S NOT ALL FUN BUT WORTH THE EFFORT WITH THESE FOLKS.STEVEN V MOORE
