I had an uncomfortable experience with the sales process here and think it's important for others…read moreto know what to expect. The pricing was not transparent; I was quoted $200/month over the phone, but in person, the price jumped to $270/month plus a $200 initiation fee. When I asked to try a class before committing, I was told that wasn't possible. The meeting focused heavily on "closing the deal" that day, using high-pressure tactics. Most concerningly, when I asked about the schedule for female instructors, the tone shifted and I was asked, "Why are you asking that?" It felt like a dismissive response to a reasonable question about a training environment. The salesperson also disparaged other local gyms, which felt unprofessional. In an activity where physical vulnerability and trust are key, this environment felt neither transparent nor supportive.

My teenage daughter and I were looking for a physical activity we could do together, and liked the…read moreself-defense benefit that Krav Maga could add. We had never taken a class, but I had read about CDK Krav Maga and we decided to give it a try. It was a great decision (especially as we have tried many different types of classes). We met with the owner DJ who took real time with us -- listening to our goals and explaining how Krav Maga builds confidence and practical self-defense skills, especially for women. We took a complementary class. Everyone made us feel so comfortable. The classes are instructional, not competitive, and people go at their own pace, which is something we also liked. The instructors are great. David worked with us initially and was knowledgeable and encouraging. DJ's wife Emma made the onboarding process so easy and welcoming. They were also incredibly flexible in helping us find a class schedule that worked for our busy lives. If you're interested in Krav Maga, CDK is a great place.

In the past I always struggled to motivate myself to regularly work out, but that completely…read morereversed when I started coming to N-Flux: I just wish I had more hours in the week for more N-Flux. First of all, the classes are challenging and engaging. The instructors do a great job pushing you just the right amount, so as you learn one thing, there is a new technique to improve. If you're like me and get bored at a regular gym, classes at N-Flux are great because you are building up to something and there is more to think about (although I'll admit my brain gets pretty slow by the end of an intense class, so I can't say *much* thinking happens at that point...). The second thing that makes me excited to get out as much as I can is that the community is incredible -- supportive, kind, funny, diverse, interesting. You definitely don't feel inadequate as someone new and inexperienced: more experienced students are always willing and eager to help out. The instructors work hard to cultivate an environment that is welcoming and supportive. So here I am, probably in the best shape of my life after just a few months, and it felt so easy! Well, not the classes, which are hard in the best kind of way, but I would take heading over to N-Flux any day over tv, social media, reorganizing, or browsing funny animal videos on the internet. If you want to learn martial arts, get in shape, and have fun doing it -- look no further, N-Flux is where it's at!

Yes,…read moreit's a gym, and the new facility in the bottom level of 1722 I Street will blow your mind with all the new equipment and toys (no more stripper poles, just tons of mats, gloves, pads and other goodies). But more importantly, this place is a community. N-Flux has the best instructors and classes you will find anywhere in DC if you're interested in taking Krav Maga, Jiu Jitsu, Boxing, and all sorts of other martial arts and combat sports. Chris and Colleen are the best instructors I've ever seen. They don't just want you to get skills, they teach concepts, conditioning, and character. Part of the training is how to be a good classmate, and experienced students help newer students and welcome new people. As a result, you're not just coming for a workout, you walk away welcomed and encouraged to be the best you can be -in everything. The classes are challenging in the best way, even their Yoga classes (and I hated yoga before I took N-Flux yoga with the amazing Scott and Maicie!). Chris and Colleen are tough and push you to be your best. Since starting, I've lost 25 pounds, gained 25 new friends, and according to my work colleagues, "am the happiest I've ever been." This place is way more than a gym and you won't know what you're missing until you come try it for yourself.
