Aj Arroyo is the founder of Optimal Power Performance (OPP) located in Tempe, Arizona. Aj has helped athletes from youth sports to professionals, achieve their highest level of performance in a variety of sports. Aj is a Certified Strength and Conditioning Specialist (CSCS) through the National Strength and Conditioning Association. He is also a certified Functional Range Conditioning mobility specialist (FRCms) certified by Dr. Andreo Spina, the creator of FRC systems.

Under Aj’s guidance, OPP has grown from only providing strength training services strictly in Arizona to now providing education, nutrition and remote coaching all over the country. Guiding both athletes and coaches on their pursuit for optimal training methods. After testing these methods for years with several athletes and himself, Aj developed OPP Training Systems, which apply scientific based strength and conditioning methods derived from theoretical research and backed by real athletes’ results.

Aj is perhaps most known for his work with baseball players. After a tough college experience not getting the results he wanted and a short professional career in lower level Independent Baseball, Aj was consumed with figuring out how and why he didn’t reach his potential. Always searching for ways to improve either in the gym or on the field. This constant search sparked the rest of his career in working with athletes for all sports. Aj is trusted by athletes whom are affiliated in MLB, NBA, and the NFL specializing in strength and speed development, hitting and throwing instruction; and athletic performance enhancement.
