Decent gym, has most basic equipment + a heavy bag so that’s a plus. Only downsides in my opinion is some of the cables have more resistance than others and 20$ for a day pass is a bit high since the gym is smaller but no other gyms in the area so i get why the price would be more

I can’t say enough about this gym. Cara and Rob were amazing coaches. They made me feel like I was a part of the gym and not just a drop in. They were very attentive, encouraging, and kind.

Thank you so so much. Can’t wait to come back.

In town for the week and my son and I wanted to get some Gym days in to stay on track. This Gym has a little bit of everything and reasonable Day and Weekly rates. You can do all machines, all free weights, cardio and more. Highly recommend this location. Convenient and easy. Can't beat it.

Keys Strength was a great place to get a couple workouts in while on a weekend trip in the Marathon. The owners were easy to get ahold of and get us setup. They had all of the equipment needed for a great workout, the place was nicely laid out, and everyone was respectful. Will DEFINITELY be back. Thank you, Chris!

Found Keys Strength and Conditioning by searching for a Concept 2 Rowing machine on C2’s website to catch a workout while vacationing in the Florida Keys. I found this place very inviting (met Elizabeth, the owner on my last visit) and the C2 Erg in very good condition even with almost 9 million meters, which is a credit to the Owners and how clean & well maintained this facility is!

I would definitely recommend vacationers to drop in for a great place to get a workout, especially when the weather was cold and rainy. My only recommendation would be to add a second C2 Rower. See you next time all the best!

This is my 3rd season coming to Marathon and my 3rd season of calling Keys Strength my second home. I have nothing but wonderful things to say about this gym: the people, the space, the energy, if I could give them a million stars I would. I typically take CrossFit classes at home but have competed in the last 3 CrossFit Open's at Keys Strength. As an adaptive athlete, it isn't always easy to have the space and attention for the adaptive specific programming. Chris, Liz, and Cara ALWAYS go out of their way to make the Open not only inclusive for me, but coach me in a way that goes beyond "great job" they provide actual tips, problem solved, helped video, you name it. The members stayed after class on occasion to cheer me on and always made me feel part of the group.

This year I have been using the 24/7 gym a lot more and the space is well maintained, clean, welcoming, and has any type of equipment you could need. Audrey at the front desk is kind and always there for encouragement and a friendly face. The team at Keys Strength are all time.

I truly appreciate every staff member and am so grateful to have a space I can go to always feel strong and empowered! If you're in the area you need to stop in and check it out! Walk on a treadmill in the AC, try a class, make some friends, try new things, I promise you won't regret it!

I signed up for this gym two months ago, Absolutely Great environment. Staff members do a Great job of maintaining a clean gym, and addressing any concern of members with rapid response. Unlike other gyms I've been to, The staff will let you know in advance if there will be any sort of renovations done to the place so that you aren't surprised walking in the very next day. Overall the people that attend this gym are super friendly and help you get through sets if and when needed.

24/7 gym was decent, plenty of equipment and staff was friendly. Everything you would need for a good workout.

Dropped in for a functional fitness class but unfortunately was a little disappointed. The space was well kept and I liked the workout and warm up.

Arrive 4 minutes late because I had biked there and was unfamiliar with the area. The first thing the coach said was “you’re late” and then proceeded to not ask my name/experience level or introduce themself. The coach ask a few questions as the class went on but I’m not sure I would have been acknowledged if not for the fact it was a three person class.

I understand they probably get a high number of drop ins but experience itself was pretty uncomfortable. I would recommend sticking to the 24/7 side.

Justin is a master of his craft. Super patient instruction and pays attention to detail. Ryan runs a super amazing No Gi class that was addicting. Jason was a great instructor and has a bright future. Rob was super helpful on the mats and is a crafty black belt. Augie was super cool and the heart of the gym.

I have worked out at Keys Strength since I moved to Marathon. The classes are a great way to get started and push yourself in a friendly and motivating environment.

My favorite part is that all workouts can be scaled to your own level of physical fitness & ability! It’s not just a one size fits all workout!

I dropped in to Keys Strength while on vacation. It was easy to sign up for a class online using Mind Body. The class times were convenient. I went to the 7am Functional Fitness (just like CrossFit). I was welcomed by Chris, the owner and coach, upon my arrival. He gave me directions on what to do while waiting for the class to start, which is nice when dropping into a new gym, since they’re all different. I had a great workout both days I went. The class was a warm up, strength work, a conditioning workout, and a cool down/stretch. Keys Strength is great, but the best part was meeting Rich Froning!

Staff has the education, is knowledgeable, and friendly! They break down each exercise by example and walk you through the workout before you begin. I was down for a week and will definitely return each time i’m back! People and atmosphere were great!

I was here vacationing in Key Colony Beach and so happy I found Keys Strength and Conditioning in Marathon. Just a 5 minute drive.

Chris has a great facility there. Thank you to Chris, Jen, and Cara for being so welcoming. They breakdown the workout, explain exercises in detail, and run some serious classes.

Great place to workout! See you next year.

My husband and I dropped in this past weekend when we were in Marathon. We went twice and had Chris as a coach and Jennifer as a coach. They were both AWESOME. The programming was great, their instruction was great, the facility was great. And they recommended so many locals spots for us to visit. Highly recommend coming here!

My family was so lucky to find an authentic hiit class gym while we were on vacation in Key Colony Beach.
Liz and Chris run a first class operation! My sons are 21 & 24 and we all got an incredible workout! We highly recommend going here!

Liz, Chris and staff were very welcoming and made us feel at home while we continued our training! The gym has a lot of the equipment you’d expect out of a functional/CrossFit oriented gyms, with all the necessities for just about any person looking to get a sweat going and improve their fitness. I definitely recommend this gym for the out of town visitor for a drop in or anyone that is looking for a place to call home (gym). Plus during our short time there, we also go to see their staff provide great motivation, encourage their clients and provide great educational sessions from proper warm-ups to advanced modalities and pre-injury identification!

Dropped in to Keys Strength and Conditioning for class while vacationing. Totally got my butt kicked in a 30 minute Tabata work out of 40 seconds working 20 seconds resting. The Assault bike and Concept skier upped the intensity level for sure. Chris gave good instruction and encouraged all along the way. I would highly recommend KSC if you want to be challenged!

This place is awesome! My family and I are staying in Marathon for the first time , and my boyfriend and I desperately needed a gym to drop in to. We came here and the owners were SO nice and so great to talk to! The gym was spacious and clean, and they let us do our own thing! If you’re on vacay or if you’re looking for a place in the area to workout, definitely come check them out!!

I had a fabulous time last week working out at Keys Strength and Conditioning! Their class times were perfect and the gym members were incredibly welcoming. The owners were fantastic and very accommodating. The classes offer many opportunities to ramp up the workout or adjust for fitness levels. I really appreciated the easy drop in/weekly program. I only wish I lived close enough to become a member!

I reached out to Keys Strength and Conditioning because I was going to be visiting Marathon for a week and I was unwilling to take a week off from training. The owners, Chris and Liz, were very accommodating to all of my needs as a weightlifter. I was able to snatch, clean, jerk, squat and do accessory work. They had even had blocks for Tkn snatches! I highly recommend this gym if you are serious about training and want a spot to get it in before conquering your day! I would even recommend it for powelifters- squat bench and deadlift in peace. Don’t worry about dropping weighs. This is one of the cleanest gyms I’ve ever been to. Definitely drop in if you are in the area. You will not be disappointed!

This place exceeded my expectations; I was attracted to it because I saw on line pictures showing equipment that would be used in Cross fit which is the kind of workouts I do back home; however, they are not designated as a cross fit gym. They design their own high intensity workouts that incorporate many functional movements like cross fit but in an environment that is not intimidating. Loved these workouts!

I am a crossfitter for the last two years. I really liked this place. My daughter who is an Oly lifter and I went here during our vacation. Prices are reasonable and staff is great. It is not a classic crossfit gym. Their workouts are long and more cardio. I really liked the change of pace, it pointed out my shortcomings.

The trainers/coaches are very passionate about fitness; and even though I’m in a group, every session feels like I have my own personal trainer, by my side, encouraging me and helping me push myself with every rep, round, and exercise. And it doesn’t matter your age, weight, or fitness level: you work at your level, and the coaches customize the exercises for your capabilities or limitations. I’ve never been so committed to exercise before; never felt that drive to go back again and again until I started at Keys Strength & Conditioning. And I owe it to the staff - Thank you, Chris, Liz, Jordan and Megan - I wouldn’t be doing this without you!

My daughter and I have been attending Keys Strength and Conditioning for approx. two years and we are happy to say that Keys Strength is the best gym in the Florida Keys! The facility offers great equipment in a bright and airy room that is constantly improving for the benefit and comfort of its members. There is plenty of floor space for stretching and core work. Their daily workouts are challenging, but incredible fun. You definitely see results if you are constant and determined to improve your health. The staff is TOP NOTCH! They are encouraging, friendly and always helpful. No one ever makes you feel self conscious and you are constantly making new friends. The owners are wonderful people that do a lot for our community and our youth. As the mother of a teenager involved in High School weightlifting, I can’t say enough about their commitment to improving the health and the lives of our youth so they can thrive in the sports they participate in. Keys Strength is easy to get to, offers plenty of parking, and several class options at reasonable prices. Keys Strength is truly a great asset to our small island.
