The Claim

Following resistance exercise, muscle damage and inflammation markers (such as CK, IL-6, and TNF-α) are not consistently associated with muscle hypertrophy and may not be necessary for muscle growth.

In plain English

Just because your muscles hurt or swell after lifting weights doesn’t mean that’s what’s making them grow—you can still get stronger and bigger even if you don’t feel sore or inflamed.

What the research says

1 study

  1. Study: An Evidence-Based Narrative Review of Mechanisms of Resistance Exercise–Induced Human Skeletal Muscle Hypertrophy

    The study says muscles grow because of how they sense and respond to lifting weights, not because they get damaged or inflamed — so soreness and inflammation aren’t required for muscle growth.
