Awesome professional crossfit box. You are always welcome for drop-in. The classes are held in German and English.

I emailed the box on March 22 to ask about. Drop in at 1000 on Saturday March 31. I was emailed back immediately saying yes come in and here are the prices. I was really excited! I took a Tram for 20 minutes and walked 10 minutes in the cold and rain only to find a locked gym. I waited until 1000 and a few people showed up and let me in but there were no coaches and the actual gym door was locked. I left at 1015 after waiting for someone to come. I have been a drop in at many boxes around the world and have never given anything less than a 5 star rating but I found this to be extremely unprofessional and an absolute waste of my time and money to get there and back. Please do not confirm a drop in on a date/time when this is poor information as I was traveling and had only limited time. Now I did not get to visit a box while in Berlin!

Best gym in Berlin. Open for two years, it offers Crossfit, Yoga, Pilates, Krav Maga, Boxing, and personal training. Also hosts special workshops from time to time. The community is friendly and tight-knit. Trainers are first rate. I love the fact that there are no mirrors! If you like back to basics training, this is for you.

Had a great workout - OpenGym session for 15 euros and full equipment available. Air conditioning (or simply room temperature) takes some getting used to, a bit too cold for me personally - competent contacts and contact via Instagram are no problem.

Awesome box for Crossfit! Complete and very well care. I have been received very gently by a very good Coach Phill. If you are visiting Berlin, I definitely recommend to “drop in “ at that box.

Very nice people, facility, and workout. I was greeted outside by someone leaving who helped me enter the facility. When I arrived downstairs, one of the coaches greeted me and showed me where I could drop my things and stretch. The workout was a team workout. It was challenging and fun to have a full class of people. Before and after the coaches stretched us out. Thank you, Scooby and team for making my time at your gym challenging and enjoyable. Hopefully I’ll be back for work again. Cheers! Tom from Boston.

This is one of the nicest boxes I’ve been to. Great training space, entire floor is matted, there are spiral stairs to go up and get a good view of the workouts and more than enough weights, bars, and equipment. The coaches did English and German and were very mobile and strong, can’t wait to visit again!

Its a great place, very well equipped, many classes, very nice people, cool WODs

Friendly people, zero attitude. If you want a gym where people aren't spending their time flexing their muscles and taking a bunch of selfies in front of a mirror, then this is the gym for you. The owner clearly puts a premium on creating a friendly atmosphere and making people feel welcome while they pursue their fitness goals. I have no qualms about recommending them; worth every penny.

Lovely CrossFit box with nice program and facilities.

I participated as a one time drop-in, so my review is mainly targeted to visitors. The box is located in the center of Berlin and is easy to reach by public transportation. Follow the signs to the back side of the building, ring doorbell and go down the stairs all the way to the bottom floor. The box is very spacious, which kind of compensates on the fact that being located three floors under the street level, the option of training outside is limited. There are lockers and showers, although I did not use them. I really enjoyed my drop-in visit, though I really can't know how this compares to regulars as I've met only one coach, one WOD and one group of crossfitters. To register, I sent an email and got a reply immediately. Some other boxes I visited in Berlin offered an online registration, which was slightly more convenient. However, I only paid when arriving to the box, which is an advantage in case I had to cancel in the last minute, as some other boxes don't allow this.

Member here for almost 4 years. First experience with crossfit here. Never looked back. Saw some other boxes in the meantime, Grenzgänger has best equipment. Some might want a dedicated open gym area, nevertheless you can do open gym during class time, too. Great coaches, dedicated classes for Gymnastics and Weightlifting. Grenzgänger leben länger! The owner put his heart blood in.

Nice gym and good training staff

Great people, great staff, nice box!

Arguably the best crossfit box in Berlin. Great space, cool coaches...

Simply the best!

Place is amazing and ultra CrossFit oriented. Staff could be nicer.

Nice crossfit place. Spacious and complete. Class is conducted in English and the coach is good. The place is near the S bahn and easy to find. Members are friendly, just as a typical crossfit place.

Great box, super nice trainer. It went very well with me, even though I was “only” there for a drop-in and still have little CrossFit experience. Price is steep at 25, - but still highly recommended!

Awesome and beautiful gym. Dropped in for the week from Boston and definitely was one of the best gyms I have been to. Huge, spacious, clean, and beautiful. Phil the head coach is awesome and all of the workouts were on point. I went to both the 6 am and 7 am classes during the week and they were filled and competitive. Thanks for having me in and running an awesome box!

The best box in Berlin! 🫶🏽 Incredibly competent and helpful trainers.

Great coaching and atmosphere.

I can highly recommend. Great box and great people!

Great box! Favo in Berlin! There's even entertainment in the dressing room 🎉

(Translated by Google) Great coaches! (Original) Tolle Trainer!

Is there anyway to get the entry code to the door, we have been missing classes because the door is locked and we haven't been given the code. Cheers

Great coach and community

Very good place to practice not only CrossFit. The trainers are 10/10 .

Perfect weather inside, amazing coaches

Great gym, great coaches!

Best CrossFit box in Berlin. Friendly staff and even athletes, wide space & all training equipment available.

Coach Katja for president 🙏🏻

Came from a drop in from the UK, was made to feel welcome and had a great session!

Best Crossfit studio in town! Great coaches and great equipment!

The trainers are professional and friendly at the same time, I’m new to CrossFit and I immediately fell in love with it. Amazing, challenging and fun box!

Very nice, big and clean Box!❤

Totally done from the workout. Pretty cool box underground ;) People and coaches are nice too,

A very large, high and well-equipped CrossFit box. The trainers are professional and yet very friendly. The community is very nice and open to new members. Due to the fact that the training location was a theater location, the box is not only an eye-catcher from the inside and at the same time still looks very authentic as a CrossFit box, but the training possibilities are enormous simply because of the high level of fastening options for gymnastics rings, climbing ropes and much more.
