New Student Intro


Welcome to N-Flux! We’re excited to have you in the studio. This page is intended to introduce you to the N-Flux philosophy and provide you with any information you may need before your first class.

Fitness That Matters

At N-Flux we believe in fitness that matters - that fitness is about what you can do for yourself and in the service of others. We foster holistic fitness in our students through three types of classes - Krav Maga, sport fighting, and strength/conditioning. Each class type is divided into levels of proficiency. Krav students must take Krav Maga Foundations until they have tested into the intermediate level course. Krav Maga Foundations tests are offered four times a year. It typically takes a student at least 3 months to prepare for a Krav Foundations test. Students seeking to rank up in the sport fighting classes do so by invitation only. Our strength and conditioning classes are avaialble to students of all levels.

Where to Find us

1722 I St.png

We are located at 1722 I St NW next to 202 Strong. Take the stairs to the lower level, go through the double doors behind the staircase, and we’re the first door on the left. Please note there is another martial arts studio called Fight Strong right next to us.

What to Expect

We do not have a front desk person. So when you arrive, check in using the iPad on the desk in the big studio and hang out until the start of class.

Your first class can feel a little overwhelming - don’t worry, that’s normal. Things fall into place quickly as you keep coming back. If you need something, ask. We’re always here to help.

What to Bring

  • Comfortable, athletic clothing (shirts should have at least short sleeves for krav and Jiu-Jitsu classes)

  • Water bottle

  • A mouthguard is encouraged but not mandatory for introductory krav classes, it is mandatory for all jiu jitsu and upper level krav classes

  • Change of shirt and a towel if you are particularly sweaty as a courtesy to your partners


Out of respect for your training partners, we request the following:

  • Clean clothes must be worn for each class taken (students must change into clean clothes for EACH class)

  • Deodorant must be worn

  • Nails should be trimmed to avoid cuts

  • Particularly sweaty students should bring a towel and an extra shirt as a courtesy to their partners

  • Shoes MUST be worn in bathrooms

Policies and Procedures

  • Classes must be reserved online through Mindbody or the N-Flux app

  • Class cancellations must be given with at least 12 hours notice. If a reservation is canceled within 12 hours of the class start:

    • Students using class packs forfeit the credit

    • Students on unlimited contracts must pay a $15 late cancelation fee

  • If a late cancelation is due to an emergency, please email to have the fee waived

2 for $30 Trial

Our 2 for $30 trial allows new students to sample any two of our course offerings for $15 each.

If a student decides to purchase an unlimited contract of any length (one month, 6 months, or 12 months) before the end of their 2 for $30 trial, their trial fee will be applied to that contract.

Please don’t hesitate to reach out should you have any additional questions or concerns. You can reach us at or (202) 340-7790
