The Underground Lab

If you’re looking for a gym where you’re welcomed and accepted no matter your strength or ability, then this is the place you want to be. The trainers are knowledgeable and encouraging, and they’ll meet you where you are on your fitness journey. The other gym members working along with you are welcoming and motivating. Literally everyone there, from the owners to the trainers to the other members, just want to help you be the best version of yourself.

When my old gym of several years closed (RIP The Summit), I lost my most important happy place. I dreaded the thought of moving on to a faceless, corporate, big box gym and never regaining that sense of joy and belonging that I’d found there. But the UGL has given me these things in spades.

This place just radiates positive and welcoming energy. The highlights of my day are often found in the mornings I spend here just getting after it with so many other inspiring, motivated, and joyful people.

Whether you’re looking for group classes, personal training, or all the equipment you could need for a great workout, this place has you covered. Did I already mention that everyone there is also incredibly nice and that the vibes are always excellent? I probably just needed to say it again.

I love you, UGL!

I love the UGL! Ben has been my trainer for a year now. He is incredibly knowledgeable! He has been so supportive and encouraging during our time together. Additionally, he individualizes my training and makes things fun, and interesting while also accommodating previous injuries. Ben is the greatest!

UGL is hands down the best gym I’ve ever experienced. I’ve been a member for about 2 1/2 months and already I’ve seen such a huge change in my body, mind and motivation. I feel stronger, fitter and better overall! I always look forward to work outs.

The trainers are knowledgeable, experienced and can tailor the workouts to any skill level. They hone in on your goals and help give you the tools to continue making progress!

I feel lucky to have met the folks at UGL (trainers and members) and am so glad they are helping me strive for a better and healthier lifestyle. Everyone is so genuine and they truly do want to see you succeed.

I can’t recommend this gym enough. It’s not just a gym, it’s a second family!

Underground Lab is definitely the best gym I have been to in Lawrence! I love how the trainers consistently mix up workouts and the workouts are always challenging but definitely doable. They have modifications for every level of fitness and it has a positive and encouraging environment every time you walk in the door. I would definitely recommend UGL to anyone looking to see results quickly and for anyone wanting to be motivated to push themselves each workout!

I’ve been attending the Underground Lab for about 3 1/2 months now and they are hands down the best gym I’ve ever attended. The staff are extremely knowledgeable on what it takes to get you to where you want to be within your abilities at that time and how to progress you past that point. All of the staff and members genuinely care about you, your goals, and helping you progress past those goals. They’ve helped me shed 30 Lbs. and build up my overall strength immensely in such a short amount of time. I look forward to continuing my journey with all the trainers and members that I not only consider friends but my second family. I strongly recommend anyone to attend and put in the effort to allow the #uglfitfam to help change your life.

The Underground Lab is just absolutely amazing! The very first time I went there was in 2012 when I got a Groupon and the set up was completely different from any other gym I'd been to. I loved the small sized "classes" that you get with a trainer. Fast Forward and I go back to use the one week free pass and can't believe how awesome they still are. Everyone was beyond friendly and helpful. You may have 5 people or 15 people in your fitness module and the trainer still finds time to chat with you, learn about you and help you get the most out of the session. Not only are you getting an amazing workout, you are having fun! It is a little more a month than most conventional gyms but that is because you are getting way more than some equipment and hoping you don't look stupid when you have to figure out how to use it. I just got a membership for UGL and I can not WAIT to start working out full time and achieving my fitness goals once again!

The UGL is the best gym I have ever attended. When walking in there is just a different vibe that truly is addicting. All staff member are astonishing, always accommodating and willing to work with your needs. Not only is this gym not that expensive but It is also in a convenient location for KU students and other Lawrence residents. It truly feels like another home and I am always able to focus and enjoy each and every workout. 100% would recommend this gym for anyone and everyone no matter what is needed.

The Underground Lab is way more than a gym. I have been a member for almost 3 years now and could not imagine life without the lab. The trainers are seriously the best - Best Trainers in Lawrence 2 years in a row!!! Out of all the gyms I have been to, there isn't a place more accepting, encouraging, and truly judgement free than the UGL.

Best place to work out. The trainers are knowledgeable, enthusiastic, encouraging and fun. I've been working out at UGL since they opened (before actually) and I wouldn't dream of leaving this gym. The atmosphere and philosophy is unique. Once you start, you won't be able to stop. They're THAT good!

In January it will be a year that I have been working out at the Lab and I am incredibly thankful!! I have not only gained strength and muscle, but most of all I have gained self worth and confidence in myself and many friendships! I have been pushed and motivated to knock down the limitations I put on myself, and shown that I am capable of a lot more than I ever imagined. The Underground Lab is a place where you will find your weaknesses, but you build them into your strengths! The trainers are amazing and the knowledge they possess is incredible. It doesn’t matter what your goals are or where you are at in your fitness journey, The Underground Lab will get you there, all the while making you feel welcomed and valued!!!

Just go look inside and you'll immediately say to yourself what everyone does, "Oh, wow... this is like the nicest gym I've ever seen." The UGL features top-quality equipment, kept in immaculate condition, arranged in a really cool and intelligent way -- allowing you to experience unique and efficient workouts that you simply CANNOT get at other fitness facilities.

The training staff is going to have you doing stuff you've never done before... every... single... time. This was crucial for me, because as soon as I start to get bored with fitness, I fall off the wagon. There's a strong sense of belonging at the Lab and I think it's because they really don't want to sell you a membership -- they want to sell you results.

Truly, The Underground Lab is one of Lawrence's best kept secrets. Highly recommend.

I have loved my time at Underground Lab because the workouts are fun, interesting, and always changing! They emphasize proper form in every exercise, and they have coaches coming around all the time to encourage us and help us get better. If you want to get more involved in the fitness community in a friendly, welcoming, non-intimidating environment, UGL is the place for that in Lawrence!

I’m new working out here at the lab. I’ve been going several times a week for a month now and have not done the same fitness class. I love the variety of the strength training and the cardio. Everyone at the lab is very nice and compliments you. The coaches and staff are fantastic. They modify moves if needed and make sure you are lifting correctly. I like the structure of how the classes are conducted.

I am thankful everyday that I found Underground Lab. The trainers are amazing and I love all the people I workout with. I leave there feeling refreshed and motivated. I never liked going to a "gym" to workout and was always self conscious at big gyms. It is a different feeling at Underground Lab. I love it!

UGL is the absolute best place to workout in Lawrence! I love the atmosphere and the attitude of both the members and the coaches. I've been working with Melissa for a few years and she is competent, compassionate and fun. There's something for everyone at UGL and you can always find a new challenge to take on.

I love the UGL, I love the fitness modules, I think the work outs never get old, I can tell you that those trainers of UGL care about you, I love how interesting all the workouts are, I am working harder than I ever have before, I fell great I go so I can get energy for my day. is a great place and you make friends at same time. I can't speak highly enough of this place. I always look forward to what work out is going to be. Love it, love it, love it.

I was a first-time gym-goer and was way out of my comfort zone. UGL has been amazing! Everyone there wants you to succeed. And for me, working towards success meant getting vulnerable. The coaches at UGL continue to make that process easier with their support, push, and encouragement.

I recommend UGL because a great place for all fitness levels. The thing that sets them apart is that they are not intimidating and truly take the time to make you feel welcome and confortable with the gym and the workouts. The workouts will push you but safety is a top priority as they are always checking your form. The trainers also know how to make your workouts fun with great music and making games out of the workouts. Think of it as adult recess and you walk away feeling stronger every day. My favorite part is the community as everyone is very supportive of one another.

LOVE! The trainers are great, the members are great, the environment is great! It's like a big family where everyone encourages one another regardless of fitness level. No judgement at the lab. I have never felt more comfortable at a gym in my life!
