I've been working out at Core X for many years now, and even though I don't live nearby, I always find myself coming back after trying gyms closer to home. There's just something special about this place. The gym is welcoming, well maintained, and the coaches genuinely care about every person who walks through the door. They create efficient, challenging workouts while making everyone feel supported, no matter their fitness level. I highly recommend stopping by and trying one of their workouts. Chances are, you'll get hooked just like I did! read more

I've been looking for a place like this! My friend and I used to work out together in the past, and I came across her story on IG where she had PT at CORE X. Immediately I was interested. She offered me a class and I came in a few days later for a free class but my husband signed me up for the entire year (2025). Got the annual special and it's worth every $ and your time. You're just in and out. No BS, no games, no wasting time. Just there to work, sweat and get results. read more

After driving past this gym for so long it was the first to come to mind when I wanted to get a personal trainer for my sons' birthday. I drove to the back part in parking lot and came across one of the instructors and told her what my plan was. She was so helpful and directed me the right way and told me to follow IG page and send a message and that same day in less than 2 hours I had a response :) David was great describing the packages and was very welcoming . He matched up my son with a great fit Moises. We both couldn't be happier. I don't regret it at all..definitely recommend Core X p read more

Isabel is an amazing coach! Always a great vibe at Core X. I highly recommend as you have many options for class hours.

I've worked out in all styles of gyms: big-box chain gyms, private gyms, Crossfit gyms, college/university gyms, even my own makeshift "crossfit" style gym at home during Covid, and no gym has wowed me like Core X has in my short time I've started with them. This happened to be right down the street from my new job, so I was happy to have found a place convenient for my schedule. I'm loving the workouts here so far--it's no fuss, no BS, just get your workout done and you're out. My kind of jam! The coaches that I've worked out with have all been great so far! I am still trying to figure out how to catch a 5am class before it fills up--still haven't been able to. :( As I approach my 50th year of life, I knew that I wanted to incorporate a lot more strength training in order to maintain good muscular structure and to help with flexibility and this gym is giving me the opportunity to improve myself every day. Thanks for this kind of program! It's exactly what I was looking for! read more

Core X Fitness - Gyms Near Me - Downey, California

If you are looking to get back in shape or if you are barely starting with your fitness journey, this is the place. I've tried different gyms (cross fit, transformation camps... but the environment wasn't it if you know what I mean; cocky attitude and all instead of encouraging one another) In this gym I feel extremely supported and motivated by the coaches and by the training group. Everyone is super nice plus you can tell you get results here because people be looking nice lol... don't know much about work outs but every time the coaches notice I'm kinda lost or even when I ask for help make me feel super welcome and supported. I am barely starting and couldn't be happier. Always looking forward to joining the training classes, the atmosphere is amazing here. read more

Too small, music is too repetitive and the place needs more cleaning While training, the trainer yells and I couldn't hear anything read more

This is a small group fitness gym that will really get you into shape with HIIT and strength training. I was a member for about a year and then I had to move away from the area, but I would highly recommend it to anyone that's serious about getting into shape, shaving the weight and looking tone. The instructors really push you to be better and are really down-to-earth people. Honestly, if you're like me and you need that extra motivation and could use the help of a coach pushing you through sets, this is the place to be. No one judges you and everyone is friendly. Special shoutout to the coaches, Eric and David, who are really fantastic trainers, but more than anything, awesome human beings. You won't regret it. read more

I have attended the Core X group fitness classes for about two months now ( 3x weekdays, 9:15 class with coach Eric). I LOVE attending this gym! It's a solid hour of fast paced effective exercises to the tune of loud, fun and energizing music! I had not properly worked out for over 3 years and had a baby in that time. I was completely out of shape and 45 pounds over my normal weight. I started very slow. Could barely do a lunge with no weights the first two weeks. But I modified each workout and asked the instructor to help me keep form so that I was targeting the intended muscle. The coach never pressured me to strain myself, he could probably tell I was at my limits. But he was encouraging during the class. I pushed through the post workout heavy soreness of the first week and then started to feel great after every workout with manageable soreness. As the weeks have gone by, I've been increasing the weights I use constantly, as I see needed. AND I've seen honest steady improvement in my strength every single week!! All of the muscles in my body feel good at the end of the week. I have more energy throughout my day. I have even attended some Saturday morning classes when I have the time and energy and I don't dread it! I should also mention that I've lost a solid 6 pounds that is not water weight! Which is great because The major reason I wanted to work out was actually to feel better and have more energy while taking care of my toddler. So the weight loss, and the improved pleasant mood is an added bonus. My little sister, who used to prefer running as her method of exercise, started attending the classes with me about a month ago. She is hooked and is now attending more times a week than I do. The gym and equipment itself was very clean and abided by COVID sanitary guidelines. We wear face masks during the entire class. We sanitize each station after every set. And I noticed an employee sanitizes the whole room before and after each class. I don't normally write reviews but I felt compelled to do so in the event that someone else might be in my shoes and is looking for a gym that offers effective and fun classes. I was searching for a gym I thought I would enjoy for a while and I was so happy once I started attending this one and honestly enjoyed it. I am sad that I will not be able to attend for the next year, as I just found out I'm pregnant and have chosen to stick to low intensity workouts during my pregnancy for personal reasons. But I'm looking forward to returning once I'm am able to!! read more

Cant believe im going into 2 yrs being part of this AMAZING gym. You are truly my happy Place Core X !!!!!! Oh Core X! I remember last year browsing through yelp to find a gym that attracted me.

Best HIIT group training in town. You get your bang for the buck I see results after trying several training camps.

I was going here for a little bit over a year There are some coaches better than others some more personable than others as well. David who is a coach as well as one of the owners has a really standoffish attitude. Seems like he has his good days and bad days and his face shows it. Personally I avoided going for his classes. When I was going there were three coaches that were awesome Walter, Jorge, and Mallory. They were all positive and had good energy. I think one or two of them are no longer there. What upset me And why I stopped going was that they continued to charge me even after gyms were closed last year. Their communication was awful. The whole situation was handled well. read more

David and Eric are both awesome coaches. Core x offers group classes and personal training. The group classes are motivating and everyone is always friendly. If you want to get results, I highly recommend this place. read more

I joined Core X Fitness In February of 2017. I love this place ! The Coaches are knowledgeable willing to help you and challenge you to reach your goals.

Core X Fitness - First workout at Core X! Loved it! - Gyms Near Me - Downey, California

I'm 100% satisfied! Background story: About 6 months ago I quite crossfit due to injuries, and not being satisfied with my results. I dropped into multiple gyms and didn't feel comfortable no luck! My goal was to always lose weight, because it was tough on my knees. But was never able to meet that goal. Crossfit always maintained my weight. I joined Cord X Fitness a week ago and I am seeing AMAZING results! Today I got on a scale and realized I lost 5lb already! A pound a day. I couldn't believe it. I made sure to check multiple scales lol I am truly thankful! All the coaches are amazing. I've been to 6 am, 6pm, 7pm and 8pm. No bad class. I love the work outs- high intensity and cardio. Love it. If you are looking for a gym. This is a gem. read more

Def worth the 5 stars! Exactly what I was looking for since I'm not beginner level nor advanced. I'm in the middle looking to elevate my workouts and really grind for some goals. Clean gym, easy access, not crowded, and best of all- they make a true connection with you and go above and beyond for the personal training side. Classes will actually make you sweat and trainers actually engage with you. read more

I highly recommend Core X and my personal trainer Coach Eric. Coach Eric is great. He makes sure I am doing each exercise correctly and is always prepared with a variation of exercises each session. I lost a total of 25 lbs in less than 2 months working out with him. Coach Eric keeps me motivated. I am very happy with my progress so far and will continue to train with him.    Don't hesitate in joining this gym. I did a lot of research for the best gym in Downey before joining Core X and I'm so glad I joined! read more

So all you ladies that are too shy to work out with a male....I highly recommend you get personal training with Yuli! read more

I haven't joined but it looks like the place is fun. Though it does seem like a lot of money for only three 5pm classes. Which is the time I would go since I'd be going after work. And going all the way first is not an option. Too bad. I hoping to join here. Maybe if they add more classes one day and I haven't joined another. read more

Great bootcamp class, shopped around different ones and this one was exactly what I was looking for. A smaller studio and not overly crowded with lots of different times. I'm a happy customer! read more
