Identify & Fix Muscle Imbalances & Injury Risks

In this episode, I tackle muscle asymmetries and imbalances — when the differences between your two sides help you, when they hurt you, and what to actually do about them. I move past the popular "10% rule" and walk through my three I's framework: how to investigate asymmetries across morphology (muscle size and shape), quality (fat infiltration inside the muscle), and functionality (strength, power, and movement); how to interpret the data using context rather than blanket numbers; and how to intervene with a practical five-step correction program built around unilateral training and plyometrics. I cover testing tools from tape measures to MRI, the research on grip-strength asymmetry and aging, and why lower-body asymmetries warrant more attention than upper-body ones. This is for athletes, coaches, and anyone who moves and wants to reduce injury risk or perform at their best.
