Coach Bill Peterson

Coach Bill Peterson is the founder of RPM Pitching, a baseball coaching and instruction service focused on helping pitchers improve performance while protecting their arms. Drawing on more than 35,000 hours of personal biomechanics research with pitchers, Peterson teaches changes to pitching technique and the use of the arm and body that he says can reduce stress, help prevent injuries, and support greater throwing velocity. His services include individual instruction, small-group coaching, clinics, biomechanics consulting, and collaborative research on pitching injuries.

He works with pitchers at different levels, including college players, and says seven of his students have been selected in the MLB Draft and his players have gone on to compete for more than 40 colleges and universities. Peterson also shares educational material about pitching mechanics, arm injuries, weighted-ball training, and injury prevention through articles and videos.
