This place is amazing! I spent many years at the big box gyms hitting the same ten machines and not showing much progress. Owner Dave and trainer CJ are amazing and genuine people. They have helped tremendously showcasing their immense knowledge and passion for moving weights. I have also gained a working day to day knowledge about choosing the right foods and setting goals to keep those pounds off. Try Underground out and prove me wrong.

I can't say enough great things about UF and the trainers (Trisha is the best :-)), I am here to write another review. Thanks to her unrelenting focus on clients health and well being, I have successfully completed another Rim to Rim (North Rim to South Rim) Hike at Grand Canyon. I couldn't even walk up my stairs a couple of years ago and I have already finished 2 hikes at Grand Canyon and conquered Humphrey's Peak - Thanks to all those brutal but effective leg days.Thank you Trisha and everyone at UF. You guys change lives :-).

This place is amazing. I have a busy work schedule and was able to get into some group sessions. I have been going for a month now and let me say I am not one to work out alone. Having Tisha help push me has made me look at my overall health, diet and goals to get to. This is a great place if you are like me and want that extra drive to get healthy. I always leave feeling the workout and always wanting to come back.

The staff at the gym is friendly, professional and encouraging. I have been working with Trish for over a year and she is the best trainer I have ever worked with. A well deserved 5 stars for this Underground Fitness.

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 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 will really change your life :-)**Pic on the left is from Dec, 2017 and the pic on the right is March, 2019 from Grand Canyon==============================If I can give 100 stars to this amazing place and trainers, I would without any hesitation :-)I probably topped the list in procrastinating everytime the thought of joining a gym crossed my mind. I am that person who spent 30 minutes in front of UF building deciding whether to step in or just get the hell out. I guess all the “fitness” planets aligned right when I made the right decision , which is probably the best one so far with regards to leading a healthy life style.I started with 206 lbs in the month of November 2017 and could barely stay for 30 minutes during the first couple of sessions. As of today (Feb 27th, 2018) , I am at 182 lbs (bye bye 24 lbs) and I feel much stronger and healthier, thanks to my trainer Trisha. I cut down close to 3 inches of my waistline and shifted from wearing ‘Large’ shirts to ‘Medium’ size.Trisha has exceptional skill and understanding of different training techniques that suited exactly what I needed (loose weight + get strong :-)) and she genuinely cares about your overall well being. When I am at session, she constantly checks whether my form was good and continues to push me beyond what I thought I can do. She also ensures that I am eating enough to meet my calorie goals. She pushed me to achieve my target and I can’t wait to see what she has in store for me.And the other trainers in the facility are super nice too. I see both Dave and Jon almost everytime and they are awesome guys , who not only encourages the people they are working with but the rest of the teams training there. This is a place where you find people from different walks of life with different backgrounds but all working towards the same goal with each and every person from UF encouraging and assisting them in that journey.I am super glad that I found UF as I could never achieve what I did in a span of 3 months. If you are in the process of finding out the best place to get healthy and get in shape, give UF a try. You won’t be disappointed.

What a great group of people and trainers! I started working out with Jon almost 18 months ago. I hadn’t actively worked out for nearly 15 years and didn’t think it was possible with my crazy schedule, but these guys make it work for me! Shout out to big Dave, Trisha and Jake too, they are always friendly, helpful and I look forward to every workout!

I can’t say enough good things about Trisha! She is patient and encouraging, while not letting you take it easy. The workouts are designed specifically for me and my personal goals and are done in a comfortable environment that isn’t intimidating but keeps me motivated to do my best at each workout. Thanks Trisha and Underground fitness for creating a space that is enjoyable for everyone, regardless of where they are at in their wellness journeys!

No words can really describe this place! It's not just another gym, not just another personal training studio. Here you will get results, results that you probably didn't know even existed! I train with Dave and Jake. They are both phenomenal and push you to strive to your ultimate goal! My ultimate goal was to get my life back and lose weight while doing it. So far 43 days in I have lost 25 lbs. You yourself have to want it ! Following the diet is top key to get what you want ! I've gained muscle and lost fat . I started in a size 42 waist and for the first time yesterday I actually fit comfortably in a 38. That's 2 sizes and 25lbs in 42 days. Going to the gym for an hour three times a week.This place and the trainers are priceless to me!! They go out of their way to help you reach your goals ! STRIVE NOW!!! MAKE THE CALL, I DID AND I'M SEEING RESULTS WITHIN THE FIRST MONTH! I couldn't thank these trainers enough.

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 ;)

Underground fitness has an incredible team of trainers who are there to help you on your fitness journey. For me, my goal was to be able to walk up a flight of stairs and not run out of breath. I have come a long way since then with the help of my amazing trainer Trisha. She has not only helped me get into shape but has assisted me in building nutritious meals that fit my lack of cooking abilities and busy schedule.
