BlackFin CrossFit®: Opinions
Fantastic experience: Huge box, awesome people!
Fantastic experience: From the moment you walk through the bay doors at Blackfin, you're treated like family. There isn't a better group of coaches & members! The staff here is top notch! Marc, the owner, is knowledgeable, caring and supportive of each of his members. Don't hesitate to stop in and give BFCF a try, you won't regret it!
Fantastic experience: I came down from Long Island and did a drop in at Blackfin. I met Coach Tristen right away and he was extremely welcoming. Great people, great box and very much so looking forward to coming back again.
Fantastic experience: I have been welcomed and challenged at this gym. I'm 5 months in and loving this gym.
Fantastic experience: Start today! Don’t wait! We’ve had great results with the coaching and support we’ve had from Blackfin Nutrition! Definitely recommend!
Fantastic experience: Love It!!!!
Fantastic experience: Amazing workouts with a even better community of people. It'll be a sad day when I have to leave the area and say goodbye to this gem.
Fantastic experience: Blackfin Crossfit is a locally owned and operated amazing gym that has a nutrition program to allow for a complete one stop shop for your personal health and fitness! The coaches are talented and eager to help you advance in whatever your goals are. Blackfin Nutrition has one on one program that helped me get on track with my meal plans and the accountability I needed to stay focused to get the results I was looking for. Most recently we had a 6 week “fall into healthy habits challenge”, this type of challenge brings the group together on a shared program to help encourage each other for additional accountability all while being fun and a little bit competitive . If you are looking for a gym or nutrition guidance I would recommend Blackfin CrossFit & Nutrition!!!
Fantastic experience: If you haven’t looked into Our Nutrition program then you should … you will receive one on one coaching and programming designed specifically for you. You will gain a wealth of knowledge regarding what foods to eat and the right amounts … with this program, My nutrition coach, Lindsey has taught me how and what to eat regarding my specific goals along with fantastic coaches I HIGHLY recommend Blackfin !!
Fantastic experience: I can't say enough about this place, but more importantly about the people and the support you receive. I started coming to BlackFin about 7 months ago, but it feels much longer than that. I was welcomed and even made friends within the first month. After only utilizing the gym for workouts, I recently joined a nutrition challenge they were putting on. The coaches were so supportive and knowledgeable about nutrition and how to achieve your goals. We had weekly challenges and a lifeline to our coach if we had any questions. This is the last week of this challenge and I have to say it really set me up for success in the future. Sure I've lost about 10 lbs and some inches, but more importantly it's help me create good habits that are easy to follow. I've already surpassed gym goals that I never thought I would be able to do, all in 6 weeks! If you're looking for some amazing nutrition coaches, supportive wonderful people, and to sweat a lot look no further than BlackFin!
Fantastic experience: I recently decided to do more for my health and my fitness. I have never liked exercise but feel that it’s not too late to start. BlackFin is a community of people who definitely care about your nutrition and fitness. I am still in the “baby step” stage of my journey. But the coaches at BlackFin all are there to help every step of the way and the group of people who go to work out are always very supportive! I would recommend BlackFin to anyone who wants to start a workout and nutrition program.
Fantastic experience: I have not done any sort of exercising since I was messed up in the Marine Corps 30 years ago. I have a lot of medical problems that keep me from doing a lot of the stuff required. They tailored the exercises according to my disabilities! I worked up a sweat, got some cardio in, and got my adrenaline going! I feel great! I recommend this! I am sore but can't wait to go back! I had a blast!
Fantastic experience: Exelente service
Fantastic experience: old school CrossFit gym, no BS, just good old gains and military friendly. Thanks for having us and we'll come again next time :)
Fantastic experience: Stopped in for a class to see what it was all about. The community was great and very inviting!
Fantastic experience: My wife and I began our CrossFit journey here 7 years ago and it was one of the best decisions we’ve made. We found a great family of friends with whom we could get physically healthy. The accountability and encouragement, along with the professional coaching, have helped us to get in the best shape of our lives. The benefits will last ya a lifetime and serve us well as we age in the coming year. It’s never too late get started, and blackfin is the perfect place to do it!
Fantastic experience: The BEST CrossFit you will find in NE Florida. If you are serious about working out, getting in shape, getting stronger, and overall healthier, than this is the place for you!!!
Fantastic experience: There is not enough good things to say about this amazing community of people. Blackfin Crossfit is THE place to be for exercise and nutrition. All the coaches truly want you to the be the best version of yourself! Take advantage of the nutrition guidance with Coach Lindsey! She practices what she preaches and makes nutrition for Crossfit easy and straightforward. I have been a member of Blackfin for 6 years. My kids were raised here and it’s a part of our family. If you’re thinking about it, stop thinking and do it!!
Fantastic experience: I have been at Blackfin since 2017 and have loved every minute of it! Blackfin has an amazing family atmosphere where there's never a shortage of people cheering and pushing you on. I have gained so much by being a part of the Blackfin family, including important knowledge about my eating habits. Lindsey has helped tremendously throughout our nutrition challenge and has always been available to get advice from and to offer encouragement! Wouldn't even think about going anywhere else!
Fantastic experience: Blackfin Crossfit is a great place to start your fitness journey!! Marc and all the coaching staff, especially the members are like family; who always motivates, encourages and supports you to reach and succeed in your fitness goals.
Fantastic experience: Been with Blackfin for 3 years now and I can’t imagine being anywhere else! Not only is it an amazing crossfit gym & environment with the best community and coaches, but they have also implemented nutrition. Lindsey has done an amazing job getting people started and focusing on nutrition. It’s simple, motivating, and effective and I’ve never felt better!
Fantastic experience: Started at BlackFin about 8 months ago. In a few short weeks it felt like home. Can’t say enough about the people and supportive atmosphere. Both members and coaches are encouraging. The positive atmosphere that they have created makes me want to challenge myself every time I go. I recently started the nutrition program. Lindsey has been incredibly supportive & I’m learning some great healthy eating habits that are easy to incorporate into my daily schedule. Best yet, I’m seeing results and have more energy. Can’t say enough great things about BlackFin CrossFit!
Fantastic experience: I have been a member here going on 4 years. I love it here! They are always adding or improving programs to help us be better. Most recently I took part in the new Nutrition program. In just a few weeks, I have seen changes in my energy levels and on the scale. The best part is that the nutrition program has been pretty easy to follow and I didn't have to cut out any food groups, so it is something that is sustainable. You should check it out if you are looking to make a change.
Fantastic experience: My whole family loves this gym! Great coaches & programming.
Fantastic experience: This place is awesome and the owner is amazing. Can't say enough about how much fun and work you can have here!! Thank y'all so much!!
Fantastic experience: Community and family. These two words are what I think of when I think of Blackfin. Amazing coaches that will help build your skill and confidence. They will always challenge you and help you challenge yourself. Superior programming that you wont find anywhere else in clay county. It's so much more than just a crossfit gym. I promise you won't regret trying it out! #crossfit #crossfitgym #crossfitcommunity #crossfitmom
Fantastic experience: There are a lot of Crossfit boxes around this area but after trying a couple, Blackfin is where we’ve made our home & part of our daily routine! They give back so much to the community, first responders & military. All of the coaches are excellent in giving feedback, helping to modify and work with you at your pace. You become part of the family & it’s a great one!
Fantastic experience: Huge supporter of troops and Veterans ! Family owned amazing support to all who join!!

Fantastic experience: Great CrossFit gym awesome owners highly recommend to anybody experienced or new to CrossFit
Fantastic experience: Amazing!!!
Fantastic experience: I started coming here a little over a month ago through the On Ramp class. I love it because it's smaller classes and I wasn't overwhelmed trying to strain myself or compete with anyone. Going into regular classes I was nervous but everyone is so nice and the trainers are awesome and supportive ! I can't wait to see my results !
Fantastic experience: The best Crossfit gym in the area. Excellent coaching, with a friendly atmosphere. Great way to truly get in shape.
Fantastic experience: My second family, my home away from home. The moment I walked into Blackfin, I felt comfortable, not intimidated. This group is by far the best! I've tried other forms of fitness, but Crossfit and Blackfin is where I've pushed myself beyond my comfort zone, and where I've seen the most changes in my endurance, ability and strength. Drop in and give it a try, you won't be sorry. #mastersathlete #silverbackstrong #almostfifty :-)
Fantastic experience: I was in Orange Park for business and wanted to squeeze in a workout. After reading Blackfin's reviews, I picked it over a couple others. It was just what I was similar to my box in San Diego, welcoming, encouraging coaches and members, and easy to schedule a workout. When I travel, I don't like having to sign up for a specific hour, confining me to that block of time. Stuff happens especially when you're on vacation or business and pre -scheduling your workout is too restrictive. Blackfin seems like a great place to start your CrossFit journey no matter what your age or fitness level and a perfect place to drop in if you're visiting the area. I'll definitely be back and will make it my CrossFit home when we move back permanently. Kris from San Diego
Fantastic experience: Look no further, this box has it all! Great programming, multiple class times, barbell and olympic lifting classes, CrossFit Kids, great coaches, camaraderie, passion all wrapped up in one! The coaches are passionate in what they do and love to see their members achieve their goals and see them succeed in all that life throws at them . When we were being relocated to the Jacksonville area, we based where we were going to live on where our next CrossFit box is. We searched the area and BlackFin had everything we wanted in a CrossFit box. While house hunting, I did a drop-in and instantly knew this was the place we wanted to be! Come in for a drop-in or just come in and watch and chat with all of us. Trust me, you won't be disappointed!
