I have worked with Trainer Dave Bess for 6 years. He has taught me how to work out smart and efficiently with effective results! His thought process on your diet is more about leading a lifestyle and allowing you to still enjoy the foods you like, while not over consuming. His approach in training is based off each individuals needs and wants and targets those specific areas.Dave has lead me to be a successful Boston Marathon Runner and 3x Ironman. As a Triathlete, I have not gone without injury and Dave knows how to work around those areas without compensating the rest of body and still concentrating on core strength and agility.Trisha Thurston has now joined Underground Fitness. She has been an incredible asset and has helped me learn how to Cross-Train to improve my fitness level, endurance and performance.This Dynamo Team is now leading me towards another Ironman Event and I could not be more enthusiastic about referring such wonderful caring people as Dave and Trisha and everyone at Underground Fitness.

I highly recommend Underground Fitness for anyone who is wanting to get in shape after having a baby! After having my second child, I lost all of my pregnancy weight on my own. However, my shape was dramatically different, and I was not filling out my clothes the way I liked. Hiring Dave Bess was the best decision I ever made! Dave set me up on a nutrition plan that allows me to eat the foods I like and still continue to lower my body fat. Using my individual nutrition plan and weight training plans, my body is transforming, and I’m feeling so much more confident.

Underground has helped change my life! Before I started with my awesome trainer Dave at the studio early this year, I was a self-conscious, insecure guy. I would try to work out on my own and attempt one-off diets with no success. Hope of achieving my goals was slipping away. When I walked into the studio for the first time, I was warmly greeted and welcomed by the man who I would soon call my very own personal trainer, Dave Bess. Being a nursing student with a lot of schoolwork on my plate, Dave understood that I have a very busy schedule and was willing to meet my individualized needs. In the past 10 months that I have been working with Dave, there has not been a single week where he has not been able to accommodate to my schedule. His level of professionalism is exceptional and he incorporates fun and learning into each workout, teaching me about different moves, muscles, and nutrition as we go along. The expert knowledge, advice, and accountability that Dave has to offer has helped transform that self-conscious boy into a more confident, stronger man. I would 100% refer anyone to Dave and the rest of the Underground team!

I’ve been working out at Underground Fitness for about 5 months now and I LOVE it! All of the trainers are fantastic and incredibly friendly. I only have done sessions with Trisha - who is great and I would recommend to anyone - and yet all the other trainers know my name and greet me. It makes it feel more like working out with friends and it takes away the intimidation I’ve always felt towards private training. That said, they don’t go easy on you with the workout. They push you to be the best you can be while still taking in your fitness levels and safety into consideration. I definitely recommend Underground Fitness!

I am a new member to Underground Fitness, and I must say I have never been so excited for my fitness and nutrition journey! I am not new to fitness, I have worked out my whole life and played college volleyball, but my body has stayed the same for as long as I can remember. I wanted a gym that would challenge me and push me to new limits. I went in for a consultation with Dave, and when I left I knew this was the place for me! Dave took the time to truly explain everything and in a way I would understand. Sometimes gyms and trainers can be intimating, but not underground fitness. When you go in , you will feel inspired and encouraged to push yourself In ways you didn’t know were possible. The best part, is the focus on nutrition. Not only are you getting a killer work out, but you’re learning how to eat and what is best for YOUR body! I could go on and on, but I will just say that I can already tell that underground fitness is going to change my life! Dave and his team are AWESOME!!

I have been working out at Underground for about 6 months now. I had lifted most of my life on my own. I never saw a trainer at my gyms that I felt could train me.. they all looked ridiculous and normally had their clients on treadmills as they checked their cell phones...It had been about 3 years since I worked out seriously, and I was really in bad shape. Apprehensively, I signed up for one on one training with John. This guy was really good... he asked about my diet and helped me put a plan together. Gave me a free app and held me accountable for what I put in my mouth.. He didn't just forget about it.. he wanted answers.. After a month of one on one I went over to group classes.Group was with Dave.. Dave is Underground Fitness' Rock Star. This guy is AMAZING. He tweaked my diet further and really tied the mind/muscle connection together for me. The gains that I have had are just amazing. Being 52, I did not think this was possible. He has really motivated me to get back into this and stick to my diet. I have lost over 35 pounds and countless inches since I have started.Finally, I have worked with Trisha on Saturday mornings. We have concentrated on Core exercises... She gets it... she listens to what you are trying to achieve and gets you there. She is on Dave and Johns level... maybe even better.All of the trainers listen to what you are saying. They do not want you in pain or puking. They want you to succeed. I highly recommend taking this road if you are looking to change your appearance, but more importantly to change how you feel and add YEARS to your life.. Your not too old or too out of shape for this group to help. Now get motivated and get to Underground!!!!

Let me start by saying I’ve been lifting for the past 20+ years. I’ve had my up and downs like everyone else. Some good consistent years and others sporadically. The past few years have been plagued with injury and poor eating habits. I finally broke down and said enough. I’ve had a few visits next door at Impact Physical Therapy (awesome place by the way) and saw people working out here and always thought it was a good place to train at. I met the owner Dave and scheduled the first workout with him, which is free by the way, and we went over nutrition and a full body workout assessment. We determined that with my schedule, it’d be best to set me up with Jake Page. I’ve been with Jake about three months now and I’m loving everyday I get to workout with him. He is knowledgeable and cares deeply for his clients wants and needs. I have been more sore (the good muscle sore) the past three months than I have ever been lifting on my own. Also, not only Jake, but everyone there at Underground is knowledgeable and happy to help the people there. You generally don’t find a business where the employees are happy and excited to be at work but they are here!

I absolutely love training at Underground Fitness. The environment here is so clean and welcoming, and the trainers are all very friendly. I train with Trisha, and I just have to say that she is the best!! She is so knowledgable, and helps me to perfect my form and is always challenging my body and mind with awesome workout routines. She will push your limits to help you reach your potential and goals! Can't say enough about the improvements I see physically and mentally. Thank you so much Trisha and Underground Fitness!! Highly recommend!

Dave has always been positive and encouraging. He is an extremely knowledgeable personal trainer. I will continue to go to Underground Fitness, and recommend you do to. (I have also worked with Trisha and she is awesome too! This place rocks). I lost my mom (my only parent for 22 years) to a sudden stoke at 44 years old. I was her only child and I just graduated from college. I was completely lost in life and extremely depressed for the last 2.5 years and as a result of bad habits and lack of guidance, I gained a tremendous amount of weight (40lbs). I was very afraid to begin personal training because I can get “psyched out” easily if someone pushes me too hard. I also have an autoimmune disorder that flares up if I feel too much stress. Thus there was a lot of fear joining a gym. BUT I tried out Underground Fitness and took a leap of faith with Dave. It has been 8 weeks and I have lost 15 lbs, 2.25 inches in my belly and I feel physically and mentally stronger than ever.
