John Drew

John Drew

Coach | Crossfit Level 1

John began CrossFit in late 2010. After years of doing the same old workouts his wife told him about this new thing she was trying called “CrossFit”. I think his quote was “ya let’s go do some burpees and box jumps”. He has been hooked ever since. Before making Nashville his home, John owned a CrossFit box in Solon, Ohio for a few years. As an educator and business owner in the Diagnostic Imaging field, John has a passion for teaching and brings that to Shackle Island. His classes can always expect the unexpected with his crazy warm-ups. John has a passion for CrossFit and the positive effect it has on changing lives. He loves to share it with seasoned CrossFitters and newcomers alike. Come by and let us help change your life!

Josh Brinson

Josh Brinson

Coach | Crossfit Level 1

Josh started CrossFit in 2013. With a background as a US Navy Helicopter Rescue Swimmer, FireFighter, and a few other things, he is no stranger to mental and physical toughness. His biggest reasons for making CrossFit part of his daily lifestyle are his wife and his two very active boys! (And to look good at the beach, let’s be honest, that’s why we all workout). CrossFit allows him to be healthy and strong enough to do anything that his family or friends are doing at a moments notice, from jumping on the trampoline, to carrying the kids upstairs when they fall asleep on the couch, a weekend obstacle course race or skiiing/hiking trip, etc. He loves to talk Nutrition, Training and Life Lessons. More than anything, he loves showing people what it means to ‘Get Fit or Die’. That may sound a little hardcore but when you see him around the gym, ask him what that means.

“Let’s get after it!”
