Absolutely, no prior boxing experience is necessary!

Our program mirrors a pro boxer's training regimen. Our classes are small (max 12 people). We are technique-focused and progress everyone individually.

Our unlimited members typically take 3-4 classes per week. During 90 Day Training Camp that may look more like 4-5 classes per week, but there is no requirement on how many classes you need to take. We recommend mixing up boxing and strength and conditioning classes each week. Our schedule rotates, so you will easily fall into the rotation!

Learn more about our signature program and class formats here.

We are located in the heart of 14th / U Street NW. More details on our studio space and the amenities available at each can be found here.

If you sign up during early registration, you'll be able to start taking classes January 1st! Before training camp officially starts on the 13th, you'll receive an email from us with details on the kick-off event and how to sign up for your initial 3D body scan.

A wonderful boxing gym for fighters of every level. The coaching staff is friendly and accessible, the facilities are clean and well-maintained. Fully recommend.”

I was hesitant to try another boxing gym because other ones in DC can be a bit too boppy, dancey, dark and techno for me. This place has that small gym feel where the people are there for more than getting skinny, they really appreciate the craft and want to get better.”
