This was my first real boxing lesson. I am very happy Shaka was my coach. He was very patient and clear in explaining techniques. He was able to teach me at my level while still teaching the rest of the class who were further ahead than me. Overall, I will absolutely be doing this again and hope to make it a part of my weekly routine.

Coach Shaka is an outstanding boxing coach. He is knowledgeable focused and truly invested in your growth. Every session is intense purposeful and pushes you to improve both physically and mentally. If you want real boxing skills better conditioning and a stronger mindset Coach Shaka is the one to train with. Highly recommend.

This gym is filled with wonderful coaches, persons working the front desk, and community at large. The space is gorgeous. The classes can be a mixture of boxing and HITT which is fantastic. Hands down one of the best fitness studios in the District.
