Coach Justin Kiser
“It took me years to find the “magic sauce”… and guess what? It’s not magic, and it’s not a sauce. As a full-time professional working 8 to 5, I weighed in at 247 pounds with 39% body fat. I was frustrated with my lifestyle and unhealthy choices... Then in 2023, a friend convinced me to run a half marathon and everything changed. I became a runner.
I kept running, started making healthier choices and soon realized I was finally on the path to a long, strong, and healthy life. Today (as of June 2025) I am 192 pounds & 19.3% body fat and happier than I have ever been.
You don’t have to go through years of trial and error like I did. With consistency, smart lifestyle shifts, and accountability, your goals are absolutely within reach. Let’s get after them together and OUTWORK yesterday.”
