You never know what to expect when trying a new workout. But from the moment you walk into Core X Fitness, you'll feel uplifted and motivated right away. Our workout is a 55 minute high intensity workout designed for all fitness levels. We allow you to set the pace and our Coaches will make sure you have a clear understanding of what the workout will consist of before you walk in.
Core X is a great fitness center for all levels. The coaches are all very personal and make you feel welcomed. They have very affordable rates. My husband and I enjoy both the workout classes as well as the personal training. I worked out at several gyms and several other fitness centers but wasn't comfortable with the trainers or the staff.

Great gym with amazing trainers. Helps you reach your goals. Very professional. Each trainer has something special about them. No matter what a persons fitness level currently is, there is always a place for them at Core X fitness. Self motivation is important when working out but luckily the trainers are very supportive and motivational during workouts. Bring water you will need it. If you forget your water that’s okay, they sell water there. Saturdays are the best with coach David. It’s all HIIT and I burn around 600-800 calories in just that group session alone.

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

I was enjoying this gym but I then found a different place that I started to go to and tried contacting this place to cancel my membership. It's been 4 MONTHS and they are still charging my account even after one of their employees have called me saying they would cancel my membership. If you're gonna go here be aware that they will continue to steal money from you long after you're gone. They won't pick up their number or respond to emails so you're stuck refuting the charges with your bank.

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

Was really looking forward to joining this gym but unfortunately I'm still waiting for that call back after the person I briefly spoke to said he'd call me back in 5 mins!

Will talk a lot about his divorce. Will cancel training if he doesn’t get a baby sitter for his kid. During covid-19 will have online service that he doesn’t follow through with. Will also open gym up early before safer at home orders are updated.

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.

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.

I am not sure if this place is not taking any more clients, but they do not seem eager for more. I have been trying to get ahold of them for four days now to clarify some questions and ask about the program. I have called twice a day, filled out a survey and have yet to hear back from them. They haven't even picked up the phone. I am sad because this gym was at the top of my list.

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!

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.

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!

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

My friends are members of Core X and today I became a member myself. I took my first class and wow...what a way to start. It only took 10 min for me to start sweating. We started off with a nice stretch and a mile run. I'm already feeling sore. Definitely looking forward to great results and making new motivating friends.

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. It took me about a month to finally make that call because as much as I wanted to start my weightloss journey I was EXTREMELY self conscious! I had convinced myself that any gym/trainer was gna judge me.... Fast forward to 1 year later and that call was the BEST decision i made! I am so glad to be part of the Core X team. I am no where close to where i want to be but I have come so far and its all thanks

I joined because I need a push and motivation. I've had a gym membership for years without results. Core X is a small group workout that pushes you to work out with no time to slack and check your cell phone. Coaches are professional , friendly and motivating. Coaches here are actually all in shape! Coach Yuli has an amazing body and is a great personal trainer! So all you ladies that are too shy to work out with a male....I highly recommend you get personal training with Yuli!

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. I tried Gyms and just felt lost overwhelmed I didn't know what to do to get results. At core X each day work outs are different and you get a full body results, and even better you get direction from the trainers. I go after Work their schedule is perfect for me. I do the group training for an hour and feel great after.
Although its challenging and some days I really need to push through it, I look forward to it specially after a stressful
