“J-Lo”
Jennifer Williamson
Coach · Nutrition & Wellness
Jennifer leads TOS Boxing’s whole-person approach to athlete wellness, supporting competitors, non-competitive athletes, and the families who help sustain them. As a PhD(c) in psychological science, Jennifer brings a research-based lens to coaching, wellness, nutrition, and behavior change. Her work focuses on helping athletes understand not only what their bodies need, but also how mindset, stress, discipline, and daily habits shape long-term performance.
Jennifer specializes in nutrition coaching for boxers moving through training, camp, and tournament preparation, helping competitors make weight safely and strategically. Her approach emphasizes education, consistency, and health rather than extreme restriction. She also works with non-competitive athletes who want to build strength, improve wellness, develop healthier routines, and feel more confident in their bodies.
At TOS, Jennifer is known for connecting the science of wellness with the lived reality of athletes and families. She understands that performance is never just physical. It is emotional, relational, and psychological. Her coaching helps athletes fuel properly, train intelligently, recover effectively, and build sustainable habits inside and outside the gym.
Her favorite boxer is her husband, DaVarryl “Touch of Sleep” Williamson, and, of course, that knockout punch.
