About Us

Optimal Power Performance (OPP) started out as an experiment in 2015 for our founder’s personal baseball career. The experiment was to test different training methodologies and player development strategies on a surplus of athletes to see what strategies would the best. Our founder Aj Arroyo, ended up collecting the data of hundreds of athletes during this process. At the time, he had no intentions of creating a baseball training company. He was just trying to figure out what works in the shortest amount of time possible. After his playing career ended in 2017, he decided to start coaching athletes full time. In 2019 he opened up our first location in Tempe AZ. It was here where he realized he could do something big. His goal was to create the first baseball facility that prioritized baseball development over revenue. He knew what is like paying for services that didn’t live up to the hype. We are here to change the industry for the better with our athletes first approach.

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 educational courses. These courses educate coaches and athletes on the application of scientific based strength and conditioning material, pitching development methods and hitting development 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 most known for his work with baseball players. Aj specializes in special strength training, speed development, mobility training, hitting/throwing instruction; and athletic performance enhancement.

 Adam started with us in 2023 during the height of our initial move into our new facility. His background is unique, as a player who was riddled with injuries for most of his collegiate career, he was forced to find a better way. Obsessed with development and eager to get back on the field, Adam was in a constant search for ways to improve his physical abilities. As a strength coach with OPP, he strives to help players get better by providing what he didn’t have access to when we played. He aims to educate each athlete he works with on the importance of staying healthy and training correctly so they can stay on the field.

Chris battled through a series of elbow and shoulder injuries in professional baseball that ultimately hindered his playing career. Those set backs ended up fueling his new found love for coaching and guiding other players in their career.
