VSI Unlimited, formerly VSI Training, is a world-class human performance organization that helps people achieve more through athletic training, fitness, and health advocacy. Founded by Kerry Johnson in 2006, VSI began as a skills-based basketball training program. Over the next 12 years, it expanded to include football training, speed and agility training, and personal fitness training. In the summer of 2018, VSI Training transitioned to VSI Unlimited with a commitment to help the Huntsville community thrive in physical, mental, educational, and emotional health. We are committed to not only helping to develop great athletes but inspiring great people with unlimited potential.
