Greg F. Anderson (born February 1966) is an American personal trainer, best known for his work with baseball player Barry Bonds, and links with BALCO. Biography Early life When Anderson was 10 years old, his father died after being shot during a gambling dispute. Anderson and Barry Bonds began a lifelong friendship when the two played middle-school baseball together in California. Bonds flourished as the team's star, while Anderson struggled to get playing time. In college, Anderson began an obsession with weight-lifting and spent long hours in the gym. He played college baseball at Fort Hays State University in Hays, Kansas with moderate success, but was advised by his coach to find a career outside of professional baseball.
