Fantastic Gym 💪🏻 New in town and checking out gyms and this one checks the boxes. Free weights, machines, clean, super staff, etc. Large weight room with several specialty fitness rooms as a bonus. This isn't a country club, but rather a solid gym and fitness facility. Justin was great and the membership options are reasonable and generous at the same time.

5/5 Stars – Fantastic Gym, Staff & Personal Training!
Florida Extreme Fitness Center is hands down one of the best gyms I’ve been to! From the moment you walk in, you feel welcomed—never out of place. The atmosphere is supportive, the staff is friendly, and the equipment - there is so much equipment, making every workout a great experience. I also love that the gym has different rooms for working out, so you can focus on what you need without feeling crowded.

I’ve been working with Angela for personal training, and she is absolutely amazing! Her workouts and weight training sessions are tough as nails but never boring. She pushes me to do my best while ensuring my form is on point, so I get the most out of every session. The progress I’ve made with her guidance has been incredible!

A huge shoutout to Roberto, the owner, who always has a great attitude and is available for any questions about the machines. His passion for the gym and its members really shows, making this a place you actually look forward to going to.

If you’re looking for a gym with an great atmosphere, all the equipment you could imagine, knowledgeable staff, classes, and expert personal training, FLEX is the place to be! Highly recommend!

Other than wishing for longer hours, great gym. The machines (old school and well-known bodybuilding variations) were great as well as the different rooms - calisthenics, weightlifting/powerlifting, general open space. Great find and for a $10 day pass, it can’t be beat!

For sure the best Gym in Jax. Staff are polite. Never to busy to get on the equipment you need. Equipment is always working unlike alot of Gyms with broken equipment. Also noticed the clients at this gym are serious. Not alot of people looking in the mirror taking selfies. Just people getting healthy and lifting. REALLY lifting.

Terrible gym with an even more terrible atmosphere; replete with roided-out, agressive, smelly "powerlifters" who cannot properly digest their protein powder. These ogre's run the gym. One of them was doing supersets with at least THREE machines AND using the most popular curl bar (40lbs). When I told him that was bad gym etiquette and proceeded to use the curl bar anyway he started stalking me around the gym. I told the manager and she 100% sided with him and saw no fault in what he was doing. She childish responded "well, you do supersets too!". I do do supersets with mutliple peices of equiptment, but if someone starts using the equipment that I'm not currently on, I understand that I have ZERO right to hog all that equipment and I let the other person use it no questions asked.

Best gym in Jax! I worked out here for nearly 2 years and can say without a doubt this is the best gym I have ever been to. The staff was always friendly and willing to help, and there is an abundance of great equipment to use for all kinds of personal fitness training methods.

Hands down best staff and gym. Everyone there (especially the employees) are extremely enthusiastic about bettering the mind and body. Don’t believe me? Go ask Roberto (the owner) about body recomping, fasting, hot/cold contrast exposure. Questions about how to keep your knees from caving in during squats? Ask Courtney (the personal trainer) which exercises will contribute to strengthening those muscles. Overall, everyone is friendly and supportive and sometimes there is a dog so that is a +.

Make sure you bring headphones! If you’re a music purist your ears will bleed, 80% of time they are playing terrible Hip hop, pop, Rock n roll EDM mashup remixes that aren’t even good. The other 20% they’re playing actual original music that I actually enjoy, not that tik tok bs

The equipment is decent, I wish they had an outdoor option but it seems like they’re working on it.
Bathroom is a little ancient too
But the gym is nice overall and the workers(not the manager) seems to be a bit awkward and give off a don’t talk to me vibe but that’s just my experience.

Best gym in Jax! Don’t waste your time and money at one of those big chain gyms that have basic equipment. Staff is friendly, knowledgeable and professional. Facility is clean and the equipment is always in working condition. Would highly recommend you cancel any membership you have at any other gym and join FLEX!

If you're looking for a gym that has plenty of squat racks, benches, Olympic platforms, and is almost never busy at night, you'll like this gym. Depending on who's working, the playlist on the stereo can be hit or miss, but bad music never stopped a gym from being good.

Hands down the best gym for strength training in town!!! I've been working out here for a little over a year and not once have I had to wait for a bench or a power rack. Most of FLEX's space is dedicated to free weights, cable machines and isolation machines and there is a lot of hardware that you won't find anywhere else in Jax. There's also a small stretch of astroturf and a yard for prowler sleds and tractor tires. The staff are professional, friendly and and very helpful. I only wish they had a sauna, but that's minor gripe compared to all else you get from this gym.

This place is the best commercial gym in Jacksonville FL. It has actual strength training equipment (monolith, belt squat, bumper plates, tires, sleds, and no shortage of squat racks), and room to actually use the toys and lift. Something other commercial gyms can't seem to understand, just because there is 8 Sq. Ft of empty floor space doesn't mean you have to stick yet another redundant machine in it that will rarely get used. But I digress. Yes, you can actual weightlift (Olympic) here and drop the bar because common sense, and bumpers. Something my old gym wouldn't let me do unless I could lower the bar softly (WITH BUMPERS!). trying to lower a max snatch is just asking for a tweak or tear. Because there is actual legit real strength equipment, the patrons are all pretty serious about their training and are more intelligent, courteous, and aware...which is almost impossible to come by in all the commercial (globo) gyms I've been in. The staff is cool AF too, which helps, because there are no stupid rules (usually caused by idiot patrons and most gyms).
