Tom Williams’ journey to Head of Performance and Sport Science for Major League Soccer (MLS) powerhouse, the Los Angeles (LA) Galaxy, began at a crossroads: pursue traditional coaching or medical pathways. As a soccer “Swiss Army knife,” he embraced early sport science alongside coaching, building a career defined by collaboration and innovation. At the Galaxy, Williams is part of a web of support that uses rich data storytelling tailored to stakeholders and players, guiding decisions and infusing value in every encounter. This system drives their three key pillars: winning championships — including their recent record-breaking sixth MLS Cup — developing a robust academy pipeline, and leading innovation. In MLS’s “cultural melting pot,” Williams balances diverse backgrounds and short-term demands like fixture congestion while employing sustainable long-term strategies. With a unique full-time cognitive department and creative approaches like dodgeball warm-ups, he combines trust and ingenuity to elevate performance and presents a blueprint for those exploring emerging sport science.

Circuit training is quick and effective way to induce training adaptations that are similar to the demands that tactical officers face in their career.

This article addresses three main areas of resistance exercise that best prepares tactical personnel for load carriage.

Get to know Army Lieutenant Colonel Nick Barringer, Program Director for the United States Army-Baylor University Master’s in Nutrition. Barringer shares how he originally planned to become a strength and conditioning coach before a nutrition course inspired him to pursue dietetics. However, it was his Certified Strength and Conditioning Specialist® (CSCS®) credential that ultimately landed him his role as the first 75th Ranger Regiment (Army Rangers) Dietitian. He recounts drawing inspiration from the Navy SEALS to start the Ranger Athlete Warrior (RAW) program and seeing the Special Operations THOR3 program follow suit — laying the groundwork for the US Army Holistic Health and Fitness (H2F) system. Barringer and McMahon discuss the synergy between strength and conditioning coaches and dietitians, as well as cultural challenges and diverse training ages in tactical settings. The pair also stress the importance of sales and building relationships before discussing basic nutrition advice and pathways into tactical and dietetics careers.

The extent to which a special operator’s training schedule can be planned in advance is often limited due to their unpredictable operational demands. However, there may be opportunities to plan for specific training during certain periods.
