About Concrete Jungle

CrossFit Concrete Jungle was born in 2013 on Upper East Side and has been training athletes ever since. We believe that fitness changes lives.

Our goal is to change the way you look, feel, move and push your limits to be the best that you can be. Our philosophy and goal is to teach people to move better through practice; to use novelty and intensity to create an environment of constant progress; to be a place to learn and grow – to improve your body AND your mind, to get strong and fast, to increase your power output, endurance and stamina, to get more flexible, stable, and balanced, and to move with grace and agility. Being physically fit is inspiring, feels good, enriches your life, and adds both years to your life, and life to your years. For us, the bottom line is this: Fitness allows you to feel and live your best.

CrossFit is a lifestyle characterized by safe, effective exercise and sound nutrition. CrossFit can be used to accomplish any goal, from improved health to weight loss to better performance. The program works for everyone—people who are just starting out and people who have trained for years.


The magic is in the movements. Workouts are different every day. To be nerdy, CrossFit workout is constantly varied, functional movement, done at relatively high intensity. What that means in English is we do a bunch of different workouts, comprised of simple body-weight and free-weight movements, and we are pushing ourselves as hard as we can on that day. CrossFit workouts can be adapted for people at any age and level of fitness.


The sense of community at CrossFit is unique; The community always provides support and the importance of social support is that it gives motivation. It is also special because it is full of like-minded people who think it is acceptable to give an all-out effort and train as hard as you want. We can scream and grunt as we lift heavy weights, we can fall to the floor in a sweaty heap after using the AirDyne, we can cry with frustration, even laugh at disasters. This is a special environment filled with incredible people who think it’s ok to do what you want and will even try and help you achieve your goals.


Yes. Everyone can do CrossFit regardless of age, injuries and current fitness level. The program can be modified for each athlete to help him or her become fitter and healthier. Grandparents and Olympians—and everyone in between—can perform modified versions of the same workout.


No. CrossFit is the fitness program that will get you in shape assuming proper nutrition is maintained. No matter what your current fitness level is, you can start CrossFit. You can start CrossFit if you’ve never worked out, if you have injuries, or if you’re sick or overweight. CrossFit workouts are modified to help each person succeed, improve fitness and take daily steps toward goals. As you become fitter, your workouts will be adjusted to challenge you at your new level.

Is CrossFit dangerous?

Anything done incorrectly can be dangerous. By going through proper technique at every class you are constantly learning and improving. In a classes you are under the watchful eye of a coach whose sole purpose is to push you outside your comfort zone while maintaining a safe environment. CrossFit done correctly is not dangerous.


  • Have you ever wanted to lift weights and not know how to or where to start? Ever thought of having a "gym" family?'s the place where not only will you know what to do and improve but, you'll have great team of members supporting and chanting for you! I walked in these doors not knowing what I signed up too and I am so happy I took a chance and put my fears to the side and challenged my body both physically and mentally. I really love this place and I mean it. The coaches are experienced, supportive and encouraging. Serge is the reason why I am still a member! He makes it worthy and believes in you and that is the driving fuel you'll need.

  • Amazing team of coaches and athletes, great quality programming and access to a variety of training programs (CrossFit, Olympic weightlifting, Strength). Flexible hours and a very welcoming environment, I've been to many other gyms and have not seen this level of charisma and support from everyone. Highly recommended.

  • Favorite workout in all of NYC. I go through ClassPass as I like to vary my workouts but anytime you want a challenge, go here. Harder than Barry's and on par with tone house. Sean is a big reason why I love going. Amazing instructor. Great motivator and great diversity of workout time after time.
