Personal Trainer & Youth Baseball Instructor
Hello there! My name is Blu Ryleigh Anderson! I currently play baseball in thee Badger Amateur Baseball Association right in my small hometown of Wittenberg, Wisconsin. I have played and been around the game my whole life and have always had a sincere passion for participating in the sport in any way possible! I have played in the B.A.B.A since I was 15 and been on my hometown team the Wittenberg Pilots for my whole baseball career! I played as a catcher my whole life until I got older and started to progress as a player and grow as an individual. I currently play right field for the Pilots but can start virtually anywhere else my team needs me to play or where I can help and benefit the team most.
As well as playing baseball, I began to develop a love and passion for football. After high school I jumped straight into the world of Semi-Pro football playing my first 3 years right here in Wausau for the very successful Central Wisconsin Spartans. When the Spartans ended their team, I took my talents to Appleton to play for the Wisconsin Ravens where I currently play as the starting middle linebacker. These past two years have been my most successful ever as I made the league’s all-star team in back to back seasons.
Along the way I developed a passion for fitness and working out. Sports and fitness go hand in hand so after high school I started to volunteer with students at my old high school training them and working out with classes of multiple students. I still currently do this as well as coach football at the high school and mentor students at the middle school in Wittenberg. In the spring of 2017 I started online schooling through the International Sports Science Association or ISSA to become a personal trainer! I am currently still enrolled in classes and looking to finish and close it out by the end of 2018. I look forward to meeting and working with folks and kids from all walks of life! God Bless!
