Aj Arroyo is the founder of Optimal Power Performance (OPP) located in Tempe, Arizona. Aj has helped athletes from youth to professional sports achieve their highest level of performance. Aj obtains the Westside Barbell Special Strength Certification from Westside Barbell. As well as the CSCS (Certified Strength and Conditioning Specialist) through the National Strength and Conditioning Association. He is certified by Driveline Baseball with the Foundations of Pitching Certification. He is also a certified Functional Range Conditioning mobility specialist (FRCms) which is an advanced mobility system developed by Dr. Andreo Spina.

Under Aj’s guidance, OPP has grown from only providing strictly strength training services in Arizona to now providing education, nutrition, baseball specific skills training and remote coaching all over the country. Guiding both athletes and coaches on their pursuit for optimal training tactics. After testing these tactics for years with several athletes and himself, Aj developed ‘OPP Training Systems’ and ‘Conjugate 4 Athletes’ educational courses. These courses educate coaches on the application of scientific based strength and conditioning means, methods, and tactics that have been derived from theoretical research and backed by real athletes’ results.

After a tough college experience not getting the results he wanted and a short lived 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 himself either in the gym or on the field. This constant search sparked the rest of his career in coaching. Aj is perhaps most known for his work with baseball players, however the work he has done with many NBA players have earned him a seat at the table when it comes to training high level basketball players. Aj specializes in special strength training, speed development, mobility training, hitting/throwing instruction; and athletic performance enhancement.
