This is my favorite workout class in all of New York. Whether you're a complete beginner or already have experience, Simmy meets you exactly where you are. The level of personal attention you get is rare — you feel seen, coached, and challenged every single time.

From day one, Simmy made me feel like I belonged. The classes are well-structured, the technique coaching is unmatched, and the community he's built keeps you coming back. Best trainer I've ever had for both conditioning and skill.

Simmy is friendly, encouraging, and incredibly dynamic as a coach. He explains everything clearly and makes you feel like a champion — no matter your level. I've never felt more motivated walking out of a class.

I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion.’
