Justin Kline is a CrossFit and endurance-focused athlete whose content blends hard training, obstacle-course grit, triathlon-style conditioning, and Ranger-inspired discipline.

I am an active dad always trying to be the best version of myself. I use my kids as motivation to be a better person. I use my fitness education to help others understand that fitness is for everyone. Skill level doesn’t matter. Just get started and you can be the best version of yourself. I also use my podcast to help spread positive motivation to anyone who might be struggling.

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics? It is the question brands ask us most, and it came up again when I joined Massimo Marinelli on the Berkida Ventures Podcast.
