StrongStrides works with all types of athletes who are performance driven.

This includes people at the recreational, masters, and elite level: anyone who wants more out of their body.

How Can You Help My Performance?

I assist athletes in achieving challenging goals by increasing understanding strengths and opportunities for growth in the body while teaching and implementing modern strategies to enhance performance and the joy of the sport experience.  My goals are your goals no matter what your objective.  Some people are trying to get back to sport life and freedom of movement. I am grateful to serve on on both ends where the margin of error is slim. 

I provide athletes with comprehensive fitness and daily routines.  Skills taught are body awareness, breathing, attentional control, visualization, energy activation and relaxation, core control, posture, alignment, technique.  Performance goals consist of freedom of movement, ease of movement, efficiency of movement, and strength of movement.  The foundation is training the core; and moving well.

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."
