Mike Polanen
Hi, I'm Mike Polanen — founder, owner and head coach of ARJ Gym. The name ARJ is derived from the first letters of my children's names: Abigail, Romee, and Justin. That sense of family isn't just personal, it's in the DNA of the entire gym.
From day one, my mission has been to create a place where everyone feels welcome. Whether you come for your fitness, self-confidence, mental resilience or a career in the ring — at ARJ, development is key. Mentally and physically. I believe that a trainer not only teaches techniques, but is also a role model. Sometimes I am a coach, sometimes a psychologist, sometimes a brother — but always with genuine attention to who is in front of me.
