Fitness Underground

Best gym in socal

The cleanest and friendliest gym I have ever been to.

Excellent gym with the best, no nonsense equipment. The gym goers here are strong and inspiring.

This gym has a nice variety of equipment. The members are friendly! During peak times it can get a little crowded.

I have been training at Fitness Underground for about a year and a half. I originally started training with Ian, the owner, to get in shape for my wedding. Ian is not the first trainer I have used but his approach to working out has truly changed my life. The first couple of months were hard, not only because I was not used to working out to that extent, but also because getting up and working out before work is difficult. Still, that hard work changed me, and I do not see myself not having a trainer like Ian ever again. Working out twice a week with Ian truly gave me the best results I have ever had. Now I have a 9-month year old baby and can only train with him once a week. I look forward to that training session every week and any chance I get, I try to squeeze another session in. I drive 30 minutes in the opposite direction to get there every week and I have no regrets. If you are looking for a gym that’s open 24/7, has legit equipment for deadlifts, squats, powerlifting in general, I promise you, Underground Fitness is where you need to be. It is of course clean, well maintained and has healthy food/snacks readily available but what is most important to me is the time, energy, and effort Ian puts into every session. I whole heartedly where the apparel and genuinely see Ian as a friend. Don’t believe me? Come on Thursday mornings so I can prove you wrong.

I found Fitness Underground through its Yelp reviews a few years ago. I was looking for an alternative to CrossFit and wanted to focus on gaining strength, so a powerlifting gym seemed like a good fit. I found this gym and have never looked back. The gym is always super clean and has a wide variety of equipment that can suit anyone's needs. I was worried about working out by myself because of intimidation, especially since I am in my mid-40s and was going to be around a lot of younger folks. But seriously, no one cares. Everyone is there to get better and help each other out. No egos. I've been doing personal training with Ian and continue to see my max lift numbers go up, which is exactly what I want. If you are looking for someplace new, grab a day pass and check this place out!

I have been personal training with Marisa for a while and I have to say it’s been the best experience ever! She motivates you, she supports you, she even provides you food menu for your journey to get successful results. She customizes your workouts based on your personal fitness level and goals. I have seen great results with her!!!!!The gym is super clean and well kept!

Great vibe, forward thinking owners, clean gym open 24 hours a day. Personal training has changed my life for the better! …

This gym is awesome! Ian, the owner, is helpful, knowledgeable and willing to lend a hand if you have a question or need guidance. His personal training programs really help you to reach your goals, no matter where you are in your fitness …
