Great place, I highly recommend this gym. Being overweight and unfit I knew I needed to change my lifestyle or get ready for the grave. I did a lot of research before I joined this gym. I choose Flex Fitness because Tony Nammari had the greatest reviews as a personal trainer and he has a totally equipped gym. I am so happy I have signed up. I see improvements already and its only been 6 days. Flex Gym rocks Apex Marble! More...

Didn't have the chance to actually start working out here due to unforeseen circumstance, but the vibe and feel of this place felt warm. Comfortable and very friendly. Really looking into an online training program being as though I now live in North OC! More...

I'm 44 this year. Since I was a kid, I've always been 'fit', when I went to college I decided to get into an actual gym and start training. I moved from weighing 141lbs to 185lbs. During my mid 20's and early 30's I had reached upward of 214lbs. Then I got married and my time I had for the gym got cut from 2 hours a day, 6 days a week to 45 minutes per day 4 times a week. THEN... when my wife and I had our wonderful son, working out was kind of... well let's just say my LA Fitness membership was getting paid, but not getting used. Our son is 2 (this weekend!), and about 8 months ago... feeling my mid section getting doughy, and gaining weight in the wrong places, and just flat out seeing all evidence that at one time I was pretty fit, going down the toilet. I was even feeling 'aged' carrying around my son. I know... I was turning into a slug. LOL. I tried getting back into the gym, things weren't the same. I was motivated, but honestly I had no accountability to push myself. And then I missed a day, 2 days, 3,4, and 2 weeks went by. Get back into the gym for a day or two, out for 6. Things didn't change. Something HAD to change. I realized if I wanted to change tomorrow, I couldn't keep doing what I had been doing... clearly it wasn't working. As I was sitting at the dentist office with my son, an ad for a fitness center showed up in my Yelp. Ha! A sign. I did a further search for person trainers, and that same place showed up as one of the higher ranked places on Yelp. I was excited and felt motivated... I was going to do something that I never thought I would do before... get a personal trainer (10 years ago, my ego would have kicked my own butt for considering this)! I called this place up, left a message for them right then and there. All that excitement was forgotten, because I didn't get a call back till Wednesday the following week! At that point I was more annoyed on how long it took for them to return a sales call from someone that was clearly motivated (and my message showed it). Plus, the person that called me back just didn't seem genuine and was too 'over-the-top' in sales mode, and failed to show interest in my goals. I decided to call the next place in Yelp called 'FlexFitness'. Wahoo! Got a live person who scheduled me in for an appointment with the owner of the Gym that day. Score!When I sat down with "Tony" (owner of Flex Fitness), my first thought was OK, this place is cool. He took the time to hammer me with a number of questions to get to know my past, present day and future goals. He dug into my eating habits. OK... now with my novel of a intro out of the way. Let me share with you a few fun facts. When I signed up, Tony took all my measurements including a body fat test. Which I was at a 19.1%. Next... week number one was hell. No joke, ever day I wanted to quit. My trainers "Alvin" and "Tony" (how cool... I had not 1 but 2 trainers!) had me pushing more weight than I did back in college days! I would come home and be exhausted and sore, VERY sore. Each day was a test of 'How bad do I want it'. I wanted to get back fit, I wanted to have the energy to play with my son and not be exhausted. So I stuck with it. 4 days a week, 1 hour a day with Alvin or Tony, and then 1 day working out on my own. Don't think you'll have the time to look at your cell phone, leave it in your car. For one hour, you'll get pushed most likely harder than you ever have. So the good stuff. Today 6 weeks after my start, not only do I feel stronger, look stronger, and eating healthier. Tony took my body fat test and measurements again. I was at a 13.8% a drop of 5.3%!! With all the rest of my numbers looking solid. The largest gain was my torso had a 2" gain. Yeah, these guys are getting an enthusiastic two thumbs up from me.To close, what makes this gym unique, is the family like environment. The trainers will push you, and make sure you get what you expected out of this gym. Lastly, the equipment in this place is like none I've seen before. More...

This is a "real" gym. Professionalism as soon as you walk through the door. All the trainers are extremely knowledgeable and will take the time to answer any questions, without a "cookie cutter" answer. I highly recommend this gym to anyone. Easy to get to off I-5 and Lake Forest. Not far from other usable amenities. Clean facility. Good music. Very nice equipment. Not much more you can ask for from a training facility. More...

I am so glad that I found Flex Fitness! Everyone there is so professional and friendly. I like the range of equipment and their location is really easy to get to off of the 5 or 405 Freeway.
