Very inviting place, the people that train there are very welcoming and it's not intimidating at all to train there no matter what your strength level is. They have power bars, a set of kilos, and even a belt squat; all you need to get stronger.
Owners are great
Atmosphere is great
Seems intimidating but it's not
Everyone here is friendly, respectful, positive and supportive
Cant find a better gym than this
I went from Golds gym to this one and the difference is like night and day. Vastly better atmosphere here and the barbells are of much better quality.
I joined this gym in early December to start getting stronger and to lose some weight, Ian and Marisa are great! In just the month I've been training my squat has gone up 45lbs and my bench has gone up 35lbs great place if you're looking for a strength training or powerlifting gym. #Underground
Fitness underground is the best gym i have ever been to! I love going to bootcamp, open gym, and personal training with Marisa! They have all the best equipment with a large variety and the best trainers who always want to help!

This gym is awesome! I enjoy coming to bootcamps in the morning at 6 am. Marisa is a great trainer, and really cares about you. If you have an injury and let her know. She will help you modify each exercise. Bootcamps are always fun and motivating. We all have such a great time. It really makes working out fun! I like that Marisa incorporates different exercises and she even does kickboxing Wednesday's.

The long and short of it is, if you're serious about reaching your fitness goals, Fitness Underground is the way to go!!
I signed up for my first ever Spartan (this one happened to be a Super), which was on Jan. 27, 2018. Leading up to that date I had been searching for a gym and personal trainer who I can trust and be comfortable with since I had a few nagging sports injuries (right knee and left shoulder). Marisa took her time to ask me questions, assess me, and review my goals. She customized personal training sessions to maximize my strengths and strengthen my weaknesses. In this case my biggest weaknesses were grip strength, core, and lower back. Marisa's technical training made a huge impact and was the difference! So much so that I dominated 23 of the 27 obstacles.
Thank you Fitness Underground!
Next stop, Spartan Beast, Sprint, and my Trifecta.

Outstanding gym, the owners Ian and Marisa really care about each individual lifters success. They have fully committed to having heir own powerlifting team that will be competing later this year. The gym atmosphere is great, something that will definitely breed greatness of each individual lifter. Best gym this side of the Mississippi
Hidden Gem for sure! They have that perfect vibe at Fitness Underground and nothing but hard working people who encourage eachother to get better. If you like strength training or powerlifting this is the best gym in tbe area hands down. Excited to watch the Underground powerlifting team compete in December!
Great workout atmosphere. Ian and Marisa are very nice and helpful. This place is unique and great for everyone who wants to reach their fitness goals!
I've been living in Upland for practically my whole life and have tried literally every gym but never felt at home. I actually found this place while going to pick up some food at the Meditteranean restaurant nearby and was very excited to get a membership after getting a tour by the owners, who are awesome by the way! I come in and do my thing and everyonce in a while I will do a drop in for group training but am not currently enrolled in the unlmited because I usually prefer training by myself. I highly recommend the open gym membership for anyone who likes to lift weights in a very cool environment! They have all the equipment I need to maintain a strong, functional mind and body. Check it out!
