#17 - Justin Cotler On Coaching Athletes, Living Your Fitness Passion & GRID

In this episode we speak with Justin Cotler, GRID League Coach and owner of CrossFit Dynamix, all the way from New York City. He is also the head coach of the GRID Games Team DC Brawlers.

Into the show, Justin shares about himself and his professional singing career. From there, we get an idea as to how he transitioned into CrossFit, allowing him to channel his addictive and competitive personality into a fitness sport. He then introduces GRID and what it’s about.

Moving forward, our crew goes to ask Justin further about decision-making from a coach’s perspective and his thoughts on weightlifting.

From here we go to our classic Good, Bad and Science! And then Justin, Tommy and Doc continue on to discuss the latest in the music industry! 

We wrap up this episode with our 9 from 9  (missing Macca for now).  Great stuff guys. Enjoy listening to this podcast!
