The best gym in Charleston!

I started at KOR4 Mount Pleasant in September, and after just a few weeks, I can already feel and see the difference. I usually hit the 5 a.m. FORCE and FLEX classes and just started the 7:30 a.m. FIRE sessions. Each one pushes me in the best way possible.

Huge shout out to Hayden and Frank, who are incredible coaches; motivating, knowledgeable, and always keeping the energy high even before sunrise. They know how to challenge you while helping you focused on form and progress.

For the past two years, I’ve rotated between Hylo, The Works, and F45 through ClassPass, but now my routine is almost entirely at KOR4, and for good reason. The programming here is intentional and effective. Every class blends strength, conditioning, and recovery in a way that delivers results. I’m improving my strength, muscle definition, and endurance with every session, and I leave each class feeling stronger and exhausted in the best ways.

The community and energy here are unmatched. Everyone shows up ready to work, but there’s also this supportive, encouraging vibe that makes you want to come back day after day. Great coaching, smart programming, and positive atmosphere!

If you’re looking for real results, incredible instructors, and a place that keeps you motivated, this is it.

🏆New PR for the 10k, and I gotta give credit where it is due! 👾KOR4 became my church back in April, & I’ve been doing 3 workouts a week ever since. It’s everything a washed up athlete needs! I call it my church because the coaches are out here doing God’s work! 😉 I mean, for the first time in 10 years I am injury free! 🙏🏼 I am stronger. I am faster. It’s super fun y’all! The lighting is moody 😈 and a bit dark. The speakers make your bones tremble! Look at the walls and see for yourself. They got HYROX flags from members/coaches who have placed! 👊🏽💥

I usually train with Cat and Frank, and they are incredible. They don’t just motivate you—they take the time to correct your form, challenge you to hit new levels, and drive you toward your goals.

Whether you’re just starting out or already a seasoned athlete, this gym is the perfect place to advance your conditioning. The energy, the coaching, and the results speak for themselves. Highly recommend Kor4 to anyone serious about leveling up their fitness! 💪🔥

Intense but for all levels of fitness, you can modify any exercise to fit your needs. Staff and trainers are all friendly, supportive and challenge you to push yourself.

Never thought I was a group fitness person or a wake up and workout before work person🤣 BUT I happily stand corrected! I have always been in the gym and sports, but for a while I lost my motivation. I started my classes back in January just to do something different because I had a free month! And oh my gosh!!! I fell in love!!! Now I go three times a week and it has helped me find my love again. I’ve toned up so much, lost some weight, gained muscle and feel great!!! 💪

This place is for everyone and has such a great variety. My favorite is the fire classes as the heat helps me detox from my job and keep old injuries at bay. I originally found this place when I had put in about 25 extra pounds from a medication I had to take and could not get those pounds off no matter what I did. After going here for a year this place helped me get into even better shape for my wedding and that was two years ago. In addition, 4 years later and I’m still challenged every time I go to class. And I will even wake up for an early class if my day is crazy with work and I’m NOT a morning person, but I love it that much! I could go on and on but google only lets us put so much 😊 if you’re considering, JUST TRY IT. You won’t lol back and you’ll be glad you did!!!

KOR4 has completely changed my life. I’ve never been part of a community like this—where every coach, every staff member, and every person alongside you truly wants to see you win. They’ve pushed me harder than I ever thought I could go, but always with encouragement, belief, and heart.

In the last six months, I’ve reached a level of fitness I didn’t even know was possible for me—and I came in already in decent shape. KOR4 shattered the ceiling I thought I had. I now find myself training for competitions like Hyrox and Spartan—something I never would have even dreamed of before. That still blows my mind.

There’s still so much further I want to go, and I know—with this place behind me—I’ll get there. If you’re looking for a gym that builds your body, your mindset, and your confidence, this is it. I couldn’t recommend it more.

If you live in the MP area, don't walk, RUN to Kor4 to sign up. This style of class is not your everyday fitness classes. This format is life changing. Personally going from never working out to everyday classes has been a gamechanger in my life and in my fitness and nutrition journey over the last 3 years. Thank you Kor4 Fam for being a community that pushes me to be better today than I was yesterday!!

I’ve been working out at kor4, 3 times a week, for almost a year. I’ve never done a repeat workout, and never get bored. The coaches are knowledgeable, encouraging and high energy. There’s a wide variety of ability and body types at the gym and coaches are happy to help you modify exercises if necessary. Highly recommend!

The facility is TOP TIER, and the whole environment is truly an elite experience. 10/10 recommend to anyone in Charleston who is looking to take their fitness routine to the next level! 💪🏼

I joined Kor4 several months ago and love it! You never get bored because the workouts change everyday and there's several different classes you can take. You won't regret trying a class out!

I just started at KOR4 3 weeks ago and I am completely hooked! These are some of the most challenging workouts I have ever done. Every day is completely different so you never know what you’re in for until you see the board. Blake has been an incredible coach and has been so encouraging! I have a rotator cuff tear that had me skeptical about being able to do the workouts…since I started at KOR4 my shoulder has gotten much stronger and the pain has subsided. I can’t say enough good things-can’t wait for the studio to open!!!

Wow, just wow! This gym is amazing and by far the best workout I’ve had in Charleston. I was very hesitant to leave my previous gym, but after I tried out one class at KOR4 I was hooked and made the switch. Great coaches, great atmosphere, great community!

Kor4 is the best investment you can make for yourself. The classes are incredibly challenging and ever changing (never a dull moment) but there’s something for everyone whether it’s Force, Flex or Fire. The coaches are patient but still hold you accountable. The community is unmatched—a place that truly feels like home. And Blake’s playlists are not to be missed ;)

This is the best gym I’ve found since moving to Charleston. It’s a community of people that really want everyone to succeed. The trainers know everyone’s name and push you to lift heavier and run/row/ski/bike faster, while other members are cheering you one (especially during the gym challenges). You never know what the daily challenge will be until that day so every day and every workout is different, especially with the 4 different types of workout classes. If you haven’t tried Kor4 yet, you need to!

Best gym and people! They hold you accountable, notice when you aren’t there, push you when you need that extra motivation and remind you there is always room for growth! Never thought I would be one to be comfortable at a “rig” but day 1 they made me feel like I could do it and here I am watching the weight go up and up and the scale go down! 💯

Kor4 is the most challenging group fitness in the area. That being said it is welcoming to those of all fitness levels from the very beginner to the seasoned athlete. You will quickly bond with the amazing coaches who will push you to your limit while bringing unparalleled energy. Fitness friends become fitness family at Kor4 and everyone works together to help each other meet his or her goals.

Amazing team here at Kor4!! All the coaches are so kind and really take the time to get to know you. They are very knowledgeable and will help each individual client’s needs. I highly recommend trying out a class. All it takes is one and you will be hooked!! I was certainly intimidated before my first class but the coaches and front desk staff really alleviate any fears and make you feel right at home. 10/10 recommend.
