Best Gyms with 24 Hour Access near Upland, California

I have been a member of Fitness Underground since June 2022. I can without a doubt say that this is the best gym I have been a part of thus far. I have been in multiple commercial gyms over the years and built a small home gym during the pandemic. My fitness journey has been up and down but became consistent during the pandemic and I started to reach my goals. However, I injured myself and started to stagnate in my physique and strength goals. Despite buying multiple training programs I improved slightly at best and not at all in most areas. I needed personal training. I looked around the area and spoke with multiple gyms and trainers. In the end, I chose Fitness Underground. This place provided me with more than I needed. The owner, Ian, show me around the gym, told me about his experience within the field, and worked with me to come up with clear goals and how I can achieve them. He was kind, and informative, and answered all my questions and concerns, especially when it came to my previous injury. He was direct and upfront about the pricing and offered competitive prices when it came to personal training. He did not pressure me into coming to the gym in any way and allowed me to think about my choice. He also asked me questions in order to understand me and my experience instead of just trying to sell me personal training like the commercial gyms have done in the past. He didn't guilt trip me. It felt like an actual collaboration. Since joining I have made more progress than I ever have on my own. He created a training program specifically tailored to myself and my goals. He would make adjustments mid-workout based on my performance. My experience with Ian has been nothing but great so far. He helped me push myself and overcome the fear that my previous back injury gave me. He does more than just tell you the workout, he helps you understand why you are doing this specific exercise and makes sure you are doing it correctly and safely. He helped me improve my strength, physique, and on top of that, my confidence. The community within this gym has been more than I ever expected. I am use to the regular commercial experience of people going in and out and nothing more. Fitness underground gave me a community that I did not realize I wanted. People were kind, supportive, and encouraging all around. They remembered who I was and can be seen supporting each other and hyping one another up. Everyone has been welcoming and became something that I looked forward to each time I showed up. I use to love it when the gym was empty, but now I show up when I know people will be there. The gym itself is kept clean, and organized, and provides you with more than enough equipment. There are a multitude of platforms to deadlift, racks to squat/bench, barbells to use, and dumbbells of weights that I cannot lift just yet. Everyone helps keep everything organized and clean. There is more than enough space to work out and nothing feels as though it is crowded. Whether your goal is bodybuilding, powerlifting, or simply just trying to improve yourself. This gym offers more than enough to help you achieve your goals. If you are looking for a gym that allows you to push yourself, has a welcoming, caring, and supportive community, equipment that allows you to test your limits and help reach your goals, or trainers that actually work with you then I can honestly recommend fitness underground.

Awesome gym!! I worked out with a personal trainer (Renato) at Fitness Underground three times a week for about six months and had a great experience. I'd never seriously lifted weights in the past and was nervous going in, but Ian, the gym owner, was very welcoming and did a great job matching me with a trainer that I'd work well with. I still consider myself to be a gym amateur (at least with respect to experience working out at other gyms), but Fitness Underground seems to have all the equipment you could need and then some. I felt like I was learning something new every session! Also it was easy to make new friends as everyone there, from the owner to the trainers to the other gym goers, was very friendly! I would usually go Tuesday, Thursday, and Saturday in the late afternoon, and the gym was never overwhelmingly crowded. Sunday mornings were especially calm (my preference). It's also always very clean and Ian invests a good amount into it as there seems to always be new machines and equipment! Finally, my man Renato deserves a shout out for his knowledge, guidance, support, and flexibility with my schedule throughout my training program at Fitness Underground! He immediately made me feel at ease upon our first session and pushed me on those days when I needed it. As for evidence of my progress, well, I have to keep buying new clothes thanks to muscle growth, so clearly Renato knows what he's doing! Overall, I highly recommend Fitness Underground if you are looking for a clean, friendly neighborhood gym to workout. I'd still be there if I hadn't moved out of the area!

Recently went to this gym and it exceeded all expectations. Had all the equipment you could think of and the staff were extremely friendly and knowledgeable. Would highly recommend to anyone looking to avoid the busy rush of public gyms!

Great gym with wonderful people. While this gym is very focused on the power lifting sport, anyone can benefit from it. The equipment is very high quality and the owner upgrades it regularly. You can access it at any time too with a key fob so there's never a concern with holidays or weekends.

I enrolled in this gym 3 months ago. My experience has been nothing short of amazing thanks to the help of my trainer Ryan I have accomplished things that I did not think I was capable of. The environment is extremely welcoming and friendly, all the equipment is very neat and well taken care of. I would also like to thank the owner Ian for letting be a part of such an amazing community.
