I signed up for Defend Yourself classes earlier this year. I'm more than halfway through my 10-week…read morecourse and I'm already sad that it's almost over. My class is made up of supportive, encouraging women and I've already found myself using some of the one-liners I've picked up from my instructor, Lauren Taylor. Things like, "your coping mechanisms are not your fault," for example, have been majorly helpful. We've spent weeks learning different defensive maneuvers and hitting targets (which is a major stress reliever) but the course also focuses a lot on assertiveness, from being able to say "no" at work to setting boundaries with harassers, family members and everyone in between. Personally, I've benefited from the lessons on deescalation tactics, learning to stay on MY message, rather than arguing, etc. It's a great course. I highly reccomend it.

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.

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.

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.

The school fosters respect, responsibility and camaraderie and my children have found lots of good friends in the school. I'm very particular about what school they go to since I have experience in taekwondo, and I highly recommend this school.

He also cursed at my son for asking for help with his headgear. He doesn't help you with advice unless he considers you developed (or if you pay for one on one coaching), and if he doesn't, he ignores you or chastises you when you ask for help.

Oh yeah, Saotome Sensei, has been training for 50 years and is one of the last surviving disciples of O-Sensei (Ueshiba) - the founder of Aikido. The dojo is run as a co-operative and your monthly dues allow you to take as many classes as you'd like. I've always liked how the most senior students and instructors are open and available to help the beginners and answer any and all questions about Aikido, etc. There are numerous classes every day and the regular class instructors are all ranked Sandan (3rd black belt) or higher. You can train before work or after. The biggest challenge is getting used to the basic moves and getting comfortable rolling. Once you start rolling with ease, you'll soon find that it's an excellent workout, in addition to a beautiful and spiritual martial art. They also have excellent instruction for children weekday afternoons and Saturday mornings.

My boyfriend was going to this gym and recommended it to me. With covid going on, I was scared of taking my brother to such activities. However, I was worried for nothing. This gym takes such great precautions with the pandemic. My brother loves coming here and looks forward to it every week. I personally never took a class here, but I would observe on the sidelines when taking my brother. I really recommend this gym and jiu-jitsu practice in general. I have much respect for this gym. The coach: He is a great teacher and especially with kids. He explains moves very well for kids to understand. He teaches discipline and yet still makes it fun for them. The coach offers private classes, which we have been doing until kid's classes open back up. My brother really enjoys his sessions with the coach and other members of the gym. My brother was awkward at first, but as classes went by, he became more comfortable. My brother would talk about his coach and what moves he taught him--shares stories about his new friends and uncles. Pandemic Precautions: Everyone wears masks during sessions. The coach would also sanitize in between sessions. There is hand sanitizer available. They are also temperature checks among arrival. Parking/Locations: The parking is limited in front of the gym. There are many spots to park though. There is additional parking at other Buisness's. Its located in a Neighborhood with lots of mini shops and studios. The gym: It is pretty spacious for private sessions, in regards to big classes. The gym max occupancy would seem to be about fifteen people. The is a bathroom available. Mats are laid out very spaciously. Classes are about an hour. Scheduling classes are very flexible. The gym is closed on Sundays.
