“I trust Coach Clif and I feel as If I had one of the best trainers while working with him at IU. Coach Clif has experience training many pro athletes and helping them become top performers at the combines. As a freshman, he helped me gain 15 pounds of lean muscle mass while increasing my vertical jump. The added muscle allowed me to play 35 minutes per game as a freshman in the B1G conference and helped me battle with older guys. Coach Clif also helped educate me on the importance of recovery by teaching me about sleep and nutrition. He also encouraged me to grow in mind, body, and spirit.” – Romeo Langford | Boston Celtics First Round Draft Pick
