About Our Gym

Hello, my name is Gamal Chasten and I am the owner of Marin Boxing.  I have been a fitness professional for over 30 years. I am certified by NASM, TRX and USA Boxing.

My introduction into fitness was by way of martial arts training. I began training in Chinese Kung-Fu styles so I could be more like one of my heroes, Bruce Lee. My first hero was the great Muhammad Ali.

Now, with heroes like that I had to do more than train if I wanted to be like them, which lead me to doing some amateur boxing and martial arts tournaments.

I received my first personal training certification in 1995, with AFAA, and I have been helping clients meet their fitness goals ever since. My specialty as a trainer is as a boxing coach and sports specific training. I am also versed in working with our senior community.
