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.

The football quarterback (QB) is a unique position in sport. To throw or pass the ball, the QB needs to incorporate nearly every muscle in the body in a very precise sequence to optimally release the ball with the right amount of power, spin, and precision. Specific movement patterns are suggested to optimize the performance of a QB.

This article proposes that all resistance training exercises can be classified as either “specific” or “general.” How to classify each exercise type and the unique benefits they offer is explained.
