Chelsea Sodaro

Ironman World Champion

"Dr. AJ Gregg is a key member of my team. He helped me come back from a career threatening injury, and guided my strength program in preparation for the most important races of my career. My program with Dr. Gregg is so much more than injury prevention, though. Dr. Gregg has helped me become a stronger, more resilient athlete, despite all of the hours I spend swimming, biking and running in a straight line. He has brought so much joy and fun into my training too.  I look forward to our session every week and I always feel better in tune with my body after we work together. A piece of my world title belongs to Dr. Gregg, and I'm so excited to see what we achieve together in the future."


Your path to a stronger stride

With years of experience guiding professional groups and individuals this training system is proven to build up, keep healthy, and round out all the aspects to develop a strong and efficient stride. I have limited availability for coaching and am seeking clients who would like to work with me for a minimum of 6 months. It takes time to see big results.
