Testimonials

I started with Jess around July this year after coming back from a stress fracture. I knew right away she was the coach I needed even before we officially started working together, because she was checking in on me throughout my recovery, when we hardly knew each other! That level of care and compassion really stood out to me. Coming back into HYROX training, I wanted to do it right, i wanted to come back smarter and better but needed someone to help me and Jess has been everything I could’ve asked for and more in a coach. She brings so much knowledge, structure, and genuine love and care into her programming, and I’ve never trusted anyone more to guide me back into sport. She’s taught me how to trust my body again and fall back in love with the process and for that I’m eternally grateful! Jess understands the mindset, the drive, and the challenges that come with training and competing as she competes herself! This is what makes her approach so much more authentic and relatable. She’s not just a coach she’s become a close friend, and I’m so grateful she came into my life when she did!

I’ve been working with Jess for just over three months now, and honestly, it’s been a game changer. I used to just train as hard as I could every session, but now every workout has purpose and structure behind it. I’m training smarter, feeling fitter, and actually understanding my training on a whole new level. Jess genuinely cares and puts so much effort into helping you succeed. Her attention to detail, quick responses and the level of support she gives are unreal. The depth she goes into with training and race day strategy is next level. It’s no surprise she’s one of the best athletes in the world.

I can't speak highly enough of Jess as a Hyrox coach! Having competed in Hyrox for two and a half years, I've had my fair share of different coaches, but the experience with Jess has been completely different. Unlike the standard cookie-cutter approach, Jess took the time to have a lengthy intro session to understand my current fitness levels, goals, and time commitments. Considering I have a young family and a demanding work role, she crafted a program specifically tailored to my needs. Every week, there's a heap of variety in the workouts, keeping me engaged and striving for more. This has significantly helped me achieve some big personal bests and race wins! But it's not just the coaching that stands out; the community of athletes Jess has built is truly amazing. Everyone helps and supports each other, creating a motivating and encouraging environment. If anyone is thinking about upping their Hyrox game, I strongly recommend jumping on the Jess Pettrow's program. You'll see your times come down and your love for Hyrox go up!
