- I started freerunning when I was 16. It just felt like an evolution of what I always wanted to do as a child: be creative, climb on things. It let me apply an adult mentality to that playfulness. Then I was introduced to veganism. And from there, I found out that the biggest percentage of pollution on the planet comes from animal agriculture. Once I discovered that, it became my calling. I think we all have something to contribute; we just have to look at the bigger picture and ask, “With what we’ve been given, what message can we promote that helps the greater good?”

- When I became vegan I stopped training for myself and started training with a purpose greater than my own. Veganism for me is about mindfulness. I do this to liberate animals. … Before I went vegan I had tendonitis, and I would get joint aches and ligament strains, and my knees would be sore. All that went away as soon as I switched to a wholefood plant-based diet. It’s anti-inflammatory, and your digestive system gets a break. … I didn’t understand what it meant to be an athlete. I was big, muscularly, but I was swollen; it wasn’t ‘healthy big’. Now I’m leaner, sharper, quicker, and my mind’s sharper too.
