FIT3D Track your progress in 3D. Learn More

Boxers are among the world’s fittest professional athletes. We base our program on the same regimen professional boxers use, driving you to achieve your best possible results.

Boxing workouts are most effective once you know the moves. We start by teaching you the basic boxing footwork, punches, and movements, helping you feel progressively more confident and strong.

Learning to box requires both physical toughness and complete mental focus. Our training will condition your body and mind, making you stronger, more agile, and able to train harder and longer.

Our classes fit together like pieces in a puzzle, each time slot rotating weekly through our four signature formats. So no matter your schedule, you will experience every element of a pro boxer’s training regimen.

With the right training, anyone can experience the benefits of boxing. At NUBOXX you’ll find first-time boxers, professional fighters, and everyone in between. Wherever you are in your boxing and fitness journey, we’ll meet you there.

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.”
