In this episode, Adam sits down with Dr. Jennifer Reiner-Marcello, a sports chiropractor with over 20 years of experience in professional baseball, collegiate athletics, and private performance rehab. Together, they dive deep into one of the most misunderstood topics in movement science—posture—and challenge the outdated notions of “good vs. bad” movement.

You’ll learn why posture is simply the body’s response to load, sport, and environment, and how performance professionals must stop forcing perfect alignment and start appreciating adaptive capacity. Dr. Marcello breaks down the concept of narrow vs. wide archetypes, explains how training affects rotational athletes differently, and offers real-world case studies from her work with MLB pitchers.

They discuss manual therapy, positional assessment, and movement retraining—tying them together across the rehab-performance continuum. You’ll hear candid takes on DNS, PRI, FMS, and SFMA and learn how Dr. Marcello integrates these models into her individualized programming strategies.
